Breast Cancer Screening Awareness,Knowledge, and Practice among Arab Women in the United Arab Emirates: A Cross-Sectional Survey

Background

Breast cancer screening can reduce morbidity and mortality and improve the survival rate for this malignancy. Low participation in screening programs has been attributable to many factors including lack of knowledge. The aim of this study was to assess breast cancer screening knowledge, attitudes and practices among women of screening age (≥40 years old) in the city of Al Ain, United Arab Emirates (UAE).

Methods

A cross-sectional survey was conducted in 2013 using the Breast Cancer Awareness Measure (CAM). Four out of twelve cultural and religious community centers in Al Ain city were randomly selected. Two hundred and forty seven women were interviewed. Chi Square test and regression analysis were used to analyze the data.

Results

Despite the increase in the uptake of screening modalities in our study group, a lack of knowledge about breast cancer screening is still evident. Almost half (44.8%) of women who never had a Clinical Breast Exam (CBE) and 44.1% of women who never had a mammography expressed a lack of knowledge about the existence of these screening techniques. Nearly one third of the participants interpreted the presence of a breast lump incorrectly and, moreover, expressed fewer worries about the nature of the lump than would normally be expected.

Conclusions

The National screening program needs to be improved and directed towards more efficient and targeted utilization of resources. Healthcare professionals play a major role in alerting women to the importance of periodic screening.     

Risk of breast cancer in women with history of benign disease of the breast.

A consecutive series of 791 women who had attended diagnostic breast clinics during 1967-70 and been found to be free of malignant disease were later traced to determine their subsequent incidence of breast cancer. Of the 770 (97%) successfully traced, 22 had developed breast cancer. Based on data from the Welsh Cancer Registry only eight cases of breast cancer had been expected, so that the excess risk for the group was 2.7. The increased risk occurred in all age groups and in women deemed "essentially normal" as well as in those who had had a pathological abnormality. The risk was increased when epithelial hyperplasia was present. No excess mortality from breast cancer was apparent, but follow up was short. More breast symptoms were experienced and more biopsies performed than expected in this group of women. Women with a past history of benign breast disease have a slightly increased risk of breast cancer. Selective screening of these women, however, may be uneconomic and a cause of groundless anxiety.     

Attendance at a breast screening clinic: a problem of administration or attitudes.

In a study of why a sample of women, aged 45-64 and registered with a group practice in Edinburgh, attended or did not attend the Edinburgh Breast Screening Clinic demographic, aetiological, social, and perceptual characteristics of attenders and non-attenders were compared. Similar proportions of attenders and non-attenders knew the chance of a breast lump being cancer and were aware of the benefits of early diagnosis and treatment. The study, however, suggests that non-attenders saw the screening clinic as a place of risk while the attenders saw screening in a positive light: 79% of non-attenders as compared with 36% of attenders said that they were afraid of cancer being found, and most women attended either to reassure themselves that they had not got breast cancer or to receive early treatment if they had. Furthermore, 72% of non-attenders as compared with 13% of attenders were anxious that their lives would be disrupted if cancer were found at the screening clinic. There may well be an important irreducible element to non-attendance due to attitudinal factors; the ethical implications of attempting to eliminate this require careful consideration.     

Age as a factor in breast cancer knowledge,attitudes and screening behaviour.

OBJECTIVE: To determine whether there are age-related differences in knowledge, attitudes and behaviour with respect to breast cancer and whether the differences reflect the age-specific Canadian recommendations on breast cancer screening. DESIGN: Telephone survey. SETTING: Two cities and five towns and their surrounding areas in Alberta. PARTICIPANTS: The age-specific, randomly selected sample comprised 1284 women aged 40 to 75 years who did not have breast cancer. Of the 1741 eligible women who were contacted, 1350 (78%) agreed to participate; 66 were excluded because of age ineligibility or a history of breast cancer. MAIN OUTCOME MEASURE: Frequency of knowledge, attitudes and behaviour with respect to breast cancer, by age group. RESULTS: Knowledge of breast cancer risk factors was generally low and decreased with age. Few women were aware of the Canadian recommendations on breast self-examination, physical examination of the breasts by a health care practitioner and mammographic screening. Older women believed they were less susceptible to breast cancer than younger women and were less likely to have positive attitudes toward screening. Self-examination was performed 9 to 15 times per year by 424 women (33%), and 810 (63%) had been examined by a health care professional in the past year. Although 664 (52%) had undergone mammography, the proportion decreased with age after age 59. The main barriers to mammography were lack of physician referral and the woman''s belief that the procedure is unnecessary if she is healthy. CONCLUSIONS: Education is needed to increase breast cancer knowledge, promote the Canadian recommendations for early detection of breast cancer and decrease negative beliefs about the disease. Changes in the behaviour of women and physicians are needed to increase the use of breast self-examination, clinical breast examination by a health care professional and mammographic screening. Reaching women in the upper range (60 to 69 years) of the target group for mammographic screening should be a focus in promoting early detection of breast cancer.     

Is mammography indicated for women with defective BRCA genes? Implications of recent scientific advances for the diagnosis, treatment, and prevention of hereditary breast cancer

About 5% of breast cancer patients have inherited their disease because of a mutation in genes encoding either the BRCA-1 or BRCA-2 proteins. Inheriting one of these mutations confers a 50% to 87% risk of breast cancer. Many physicians faced with such a patient would, at a minimum, suggest increased and earlier screening for breast cancer by routine mammography.[1] Normally, regular mammographic screening combined with appropriate and prompt treatment can reduce mortality from breast cancer by 30% in women aged 50-59 years and by about 14%-18% in women aged 40-49. There are no controlled clinical trials for screening young women who have multiple first-degree relatives developing breast cancer before age 45, or those known to carry BRCA-1 or BRCA-2 mutations. In fact, recent advances point out that BRCA-1 and BRCA-2 gene products are needed to repair radiation damage to DNA.[4,5] Based on this finding, I propose that women with defective BRCA genes are likely to have an inordinate sensitivity to radiation, and this raises a question about the advisability of routinely screening these women by frequent mammography.     

Evaluation of the cervical cytology screening programme in an inner city health district.

District health authorities have been instructed to operate a cervical cytology call and recall screening programme using the age-sex registers held by family practitioner committees. A detailed evaluation of implementation in an inner London district showed that 477 out of 687 (69%) invitation letters sent to women by the family practitioner committee were either inaccurate or inappropriate: almost half of the recorded addresses were incorrect and a further fifth of the women were not eligible for a test. Overall, 90 women had a smear, which is only 13% of the total but 43% of those found to be eligible. The findings did not differ significantly with age. The findings have major implications not only for the effectiveness of call and recall for screening for cervical cancer but also for the future development of screening for breast cancer in such areas.     

Diagnosis delay in Libyan female breast cancer

ABSTRACT: BACKGROUND: To study the diagnosis delay and its impact on stage of disease among women with breast cancer on Libya METHODS: 200 women, aged 22 to 75 years with breast cancer diagnosed during 2008--2009 were interviewed about the period from the first symptoms to the final histological diagnosis of breast cancer. This period (diagnosis time) was categorized into 3 periods: <3 months, 3--6 months, and >6 months. If diagnosis time was longer than 3 months, the diagnosis was considered delayed (diagnosis delay). Consultation time was the time taken to visit the general practitioner after the first symptoms. Retrospective preclinical and clinical data were collected on a form (questionnaire) during an interview with each patient and from medical records. RESULTS: The median of diagnosis time was 7.5 months. Only 30.0% of patients were diagnosed within 3 months after symptoms. 14% of patients were diagnosed within 3--6 months and 56% within a period longer than 6 months. A number of factors predicted diagnosis delay: Symptoms were not considered serious in 27% of patients. Alternative therapy (therapy not associated with cancer) was applied in 13.0% of the patients. Fear and shame prevented the visit to the doctor in 10% and 4.5% of patients, respectively. Inappropriate reassurance that the lump was benign was an important reason for prolongation of the diagnosis time. Diagnosis delay was associated with initial breast symptom(s) that did not include a lump (p < 0.0001), with women who did not report monthly self examination (p < 0.0001), with old age (p = 0.004), with illiteracy (p = 0.009), with history of benign fibrocystic disease (p = 0.029) and with women who had used oral contraceptive pills longer than 5 years (p = 0.043). At the time of diagnosis, the clinical stage distribution was as follows: 9.0% stage I, 25.5% stage II, 54.0% stage III and 11.5% stage IV.Diagnosis delay was associated with bigger tumour size (p <0.0001), with positive lymph nodes (N2, N3; p < 0.0001), with high incidence of late clinical stages (p < 0.0001), and with metastatic disease (p < 0.0001). CONCLUSIONS: Diagnosis delay is very serious problem in Libya. Diagnosis delay was associated with complex interactions between several factors and with advanced stages. There is a need for improving breast cancer awareness and training of general practitioners to reduce breast cancer mortality by promoting early detection. The treatment guidelines should pay more attention to the early phases of breast cancer. Especially, guidelines for good practices in managing detectable of tumors are necessary.     

Early diagnosis of breast cancer: experience in a consultant breast clinic.

Of 2839 women referred to a consultant breast clinic for clinical, mammographic and thermographic examination, 480 underwent biopsy and 126 were found to have cancer. Ten percent of the tumours were occult and were classified as very early biologic disease; they were identified by routine mammography in women whose breasts were clinically normal. Biopsy of solid mass lesions non-suspicious on mammography identified 20% of the cancers; half these lesions, classified as early biologic disease, were discovered by doctors at routine annual clinical breast examination, though the earliest cancers were detected by women who were confident and competent in monthly self-examination of the breasts. Biopsy of solid mass lesions suspicious on mammography identified 70% of the cancers; these were classified as late biologic disease. Skin or nipple dimpling or retraction was evident in two thirds of the patients; their lesions seemed to be later biologically than the lesions of the patients without clinical signs, and 75% had discovered the lesions themselves accidentally.     

Screening and self examination for breast cancer.

Breast cancer is the major form of cancer in women, with nearly 30,000 new cases and over 15,000 deaths in the United Kingdom each year. Breast screening by mammography has been shown in randomised trials to reduce mortality from breast cancer in women aged 50 and over. An NHS breast screening programme has been in operation in the United Kingdom since 1988. Its aim is to reduce mortality from breast cancer by 25% in the population of women invited to be screened. The uptake of mammography among the eligible population may be the single most important determinant if the programme is to be effective. Primary care teams have an important part to play in encouraging women to attend for screening and in providing information, advice, and reassurance at all stages of the screening process. To date, routine breast self examination has not been shown to be an effective method of screening for breast cancer and should not therefore be promoted as a primary screening procedure. There is, however, a case to be made for women to become more "breast aware."     

Screening for cancer.

Screening has proved effective for only two cancer sites, the breast and the cervix uteri. Only for these, therefore, should screening be a part of routine clinical practice. The degree to which screening is effective depends on whether appropriate groups are screened. For cancer of the breast, current evidence justifies mammographic screening every two years only from the age of 50, continuing at least to the age of 70. The place of breast self-examination and physical examination of the breasts is under investigation, but these procedures should probably be used in all women after the age of 40. For cancer of the cervix, nearly maximal efficacy is obtained by screening sexually active women every three years from the age of 25 to 60. Older women who have not been screened regularly should be screened. Other screening techniques to detect cancers, such as the rectal examination, sigmoidoscopy, and fecal occult blood tests for colorectal cancer, are still experimental. Organizational and other difficulties will prevent screening programs from making a major contribution to reducing overall cancer mortality by the year 2000. If organizational problems can be overcome, however, screening may control invasive cancer of the cervix and make a major contribution in reducing breast cancer mortality in the future.     

Need for open access non-screening mammography in a hospital with a specialist breast clinic service.

OBJECTIVE--Assessment of open access non-screening mammography in a hospital with a breast clinic. DESIGN--Retrospective analysis of patients sent for first mammogram to our open access service by general practitioners and breast clinic in the year April 1989 to March 1990. SETTING--District general hospital serving 200,000 people before the introduction of breast screening. SUBJECTS--361 symptomatic women referred directly by general practitioners and 226 women referred by the breast clinic for first, non-screening mammograms. MAIN OUTCOME MEASURES--Radiographic reports on all patients. Final diagnosis in patients reported as having possible or probable neoplasm. RESULTS--Of the women referred directly by general practitioners one (0.2%) was reported as showing probable malignancy (later histologically confirmed) and 15 (4%) as showing possible malignancy (on follow up none had proved malignancy). Of the women referred by the breast clinic 38 (17%) were reported as showing probable malignancy (all had confirmed carcinomas) and 35 (15%) as showing possible malignancy (19 (54%) had proved malignancy). 18 of the proved malignancies were in women under 50 years old, 26 were in women over 64 years, and 14 were in women of screening age. 54 (93%) of the 58 patients with proved breast cancer and an abnormal mammogram had a discrete breast lump. CONCLUSIONS--General practitioners accurately divided women into low and high risk groups, resulting in few abnormalities being detected in patients referred directly for mammography. This suggests that an open access non-screening mammography service for general practitioners is unnecessary in an area with a specialist breast clinic. The large proportion of cancers in women outside of screening age emphasises the need for such clinics.     

Increased risk of breast cancer in women with false-positive test: The role of misclassification

IntroductionStudies have shown that women with a false-positive result from mammography screening have an excess risk for breast cancer compared with women who only have negative results. We aimed to assess the excess risk of cancer after a false-positive result excluding cases of misclassification, i.e. women who were actually false-negatives instead of false-positives.MethodWe used data from the Copenhagen Mammography Screening Programme, Denmark. The study population was the 295 women, out of 4743 recalled women from a total of 58,003 participants, with a false-positive test during the screening period 1991–2005 and who later developed breast cancer. Cancers that developed in the same location as the finding that initially caused the recall was studied in-depth in order to establish whether there had been misclassification.ResultsSeventy-two cases were found to be misclassified. When the women with misclassified tests had been excluded, there was an excess risk of breast cancer of 27% (RR = 1.27, 95% confidence interval (CI), 1.11–1.46) among the women with a false-positive test compared to women with only negative tests. Women with a false-positive test determined at assessment had an excess risk of 27%, while false-positives determined at surgery had an excess risk of 30%.ConclusionsThe results indicate that the increased risk is not explained only by misclassification. The excess risk remains for false-positives determined at assessment as well as at surgery, which favours some biological susceptibility. Further research into the true excess risk of false positives is warranted.     

Multiple fluoroscopy of the chest: carcinogenicity for the female breast and implications for breast cancer screening programs.

The risk of radiation carcinogenesis has been established for breast tissue from experience with total body irradiation and multiple fluoroscopy of the chest with the patient prone. The doubling dose has been estimated to lie between 20 and 50 rads. Before undertaking radiologic screening programs for breast cancer, therefore, it is necessary to determine whether exposures below this range are safe. Of 792 women who had had tuberculosis and were followed for a minimum of 20 years, 451 had had multiple fluoroscopy while supine; 341 had not had fluoroscopy. The first group received a total radiation dose to the breast averaging 17 rads (141.5 fluoroscopies); the incidence of breast cancer in this group was not increased. Had fluoroscopy been performed with the patient prone the total radiation dose would have averaged 308 rads. The difference is thought to explain the increased incidence of breast cancer attributable to fluoroscopy given with the patient prone. Mid-breast exposure with mammography or xeroradiography varies between 3 and 6 rads. Repetitive screening would, therefore, appear safe provided total exposure did not exceed 20 rads. With this restriction there would appear to be no reason to curtail screening of women for breast cancer.     

Invasive Breast Cancer After Initiation of Testosterone Replacement Therapy in A Man—A Warning To Endocrinologists

ObjectiveTo alert fellow endocrinologists of a rare side effect of testosterone therapy, for which men with hypogonadism must receive appropriate counseling and monitoring.MethodsWe present clinical features, laboratory data, and histopathologic findings in a man with hypogonadism who received testosterone replacement therapy.ResultsA 61-year-old man was referred to an endocrinologist after presenting to his general practitioner with erectile dysfunction and low libido. He had no history of hypothalamic, pituitary, or testicular disorders. There were no other illnesses or medications to account for low testosterone levels. Physical examination was unremarkable. There was no family history of malignant disease. Biochemical investigations confirmed the presence of primary hypogonadism, for which no cause (including Klinefelter syndrome) was identified. Testosterone therapy was initiated to improve sexual function and preserve bone density. Five weeks later, the patient returned to his general practitioner, complaining of a gradually enlarging lump in his right breast. When biopsy showed breast cancer, testosterone therapy was discontinued. Right mastectomy and axillary node clearance were performed. Further histologic examination revealed estrogen receptor-positive, invasive carcinoma, without nodal involvement. The patient remains on tamoxifen therapy and is undergoing follow-up in the breast clinic. After 6 months of treatment, estradiol levels were undetectable, and testosterone levels remained low.ConclusionAlthough breast cancer has been described in men with hypogonadism receiving long-term testosterone replacement therapy, to our knowledge this is the first report of breast cancer becoming clinically manifest after a short duration (5 weeks) of testosterone treatment. This case should remind clinicians that men receiving testosterone therapy should be warned of the risk of not only prostate cancer but also breast cancer. Patient self-monitoring and breast examinations by the attending physician are recommended. (Endocr Pract. 2008;14: 201-203)     

Clinical Breast Examination As the Recommended Breast Cancer Screening Modality in a Rural Community in Malaysia; What Are the Factors That Could Enhance Its Uptake?

Breast cancer is the most common cause of deaths and the most frequently diagnosed cancer among women worldwide. This study aimed to determine the prevalence of breast cancer screening, specifically on clinical breast examination, and the predictors of its uptake among women in Malaysia. A cross-sectional study was carried out in five selected districts whereby women aged between 20 to 64 years old, from a total of 1000 households were interviewed. A total of 1192 women responded to the survey of which 53.3% reported had ever done clinical breast examination. Significant associations with clinical breast examination were noted for income and distance from the hospital. These factors should be considered in developing interventions aimed at promoting clinical breast examination. In particular, healthcare providers should be proactive in raising awareness about clinical breast examination among women in Malaysia.     

Breast self-examination: importance of technique in early diagnosis.

Shortly after diagnosis of breast cancer 416 patients were interviewed about their use of screening procedures and the method of tumour detection. Although 72% reported that they performed breast self-examination (BSE), only 12% actually inspected and palpated their breasts monthly. BSE was not significantly associated with tumour size or involvement of the lymph nodes; however, thorough inspection was associated with smaller tumours, and careful palpation with the absence of palpable nodes. Of those who no longer or never had examined their breasts 40% reported having annual breast examinations by their physician and had significantly smaller tumours than did the others. Most of the women (86%) reported having detected their own tumours, and BSE did not significantly increase the likelihood of self-detection. The frequency of use of screening procedures was similar in a sample of women without breast cancer.     

Effectiveness of the public health policy for breast cancer screening in Finland: population based cohort study.

OBJECTIVE: To evaluate the effectiveness of screening for breast cancer as a public health policy. DESIGN: Follow up in 1987-92 of Finnish women invited to join the screening programme in 1987-9 and of the control women (balanced by age and matched by municipality of residence), who were not invited to the service screening. SETTING: Finland. SUBJECTS: Of the Finnish women born in 1927-39, 89893 women invited for screening and 68862 controls were followed; 1584 breast cancers were diagnosed. MAIN OUTCOME MEASURES: Rate ratio of deaths from breast cancer among the women invited for screening to deaths among those not invited. RESULTS: There were 385 deaths from breast cancer, of which 127 were among the 1584 incident cases in 1987-92. The rate ratio of death was 0.76 (95% confidence interval 0.53 to 1.09). The effect was larger and significant (0.56; 0.33 to 0.95) among women aged under 56 years at entry. 20 cancers were prevented (one death prevented per 10000 screens). CONCLUSIONS: A breast screening programme can achieve a similar effect on mortality as achieved by the trials for breast cancer screening. However, it may be difficult to justify a screening programme as a public health policy on the basis of the mortality reduction only. Whether to run a screening programme as a public health policy also depends on its effects on the quality of life of the target population and what the resources would be used for if screening was not done. Given all the different dimensions in the effect, mammography based breast screening is probably justifiable as a public health policy.     

Time-related improvement of survival in resectable gastric cancer: the role of Japanese-style gastrectomy with D2 lymphadenectomy and adjuvant chemotherapy

Background

Late presentation of patients at advanced stages when little or no benefit can be derived from any form of therapy is the hallmark of breast cancer in Nigerian women. Recent global cancer statistics indicate rising global incidence of breast cancer and the increase is occurring at a faster rate in populations of the developing countries that hitherto enjoyed low incidence of the disease. Worried by this prevailing situation and with recent data suggesting that health behavior may be influenced by level of awareness about breast cancer, a cross-sectional study was designed to assess the knowledge, attitude and practices of community-dwelling women in Nigeria towards breast cancer.

Methods

One thousand community-dwelling women from a semi-urban neighborhood in Nigeria were recruited for the study in January and February 2000 using interviewer-administered questionnaires designed to elicit sociodemographic information and knowledge, attitude and practices of these women towards breast cancer. Data analysis was carried out using Statistical Analysis Software (SAS) version 8.2.

Results

Study participants had poor knowledge of breast cancer. Mean knowledge score was 42.3% and only 214 participants (21.4%) knew that breast cancer presents commonly as a painless breast lump. Practice of breast self examination (BSE) was low; only 432 participants (43.2%) admitted to carrying out the procedure in the past year. Only 91 study participants (9.1%) had clinical breast examination (CBE) in the past year. Women with higher level of education (X² = 80.66, p < 0.0001) and those employed in professional jobs (X² = 47.11, p < 0.0001) were significantly more knowledgeable about breast cancer. Participants with higher level of education were 3.6 times more likely to practice BSE (Odds ratio [OR] = 3.56, 95% Confidence interval [CI] 2.58–4.92).

Conclusion

The results of this study suggest that community-dwelling women in Nigeria have poor knowledge of breast cancer and minority practice BSE and CBE. In addition, education appears to be the major determinant of level of knowledge and health behavior among the study participants. We recommend the establishment and sustenance of institutional framework and policy guidelines that will enhance adequate and urgent dissemination of information about breast cancer to all women in Nigeria.     

Screening for squamous cervical cancer: duration of low risk after negative results of cervical cytology and its implication for screening policies. IARC Working Group on evaluation of cervical cancer screening programmes.

A collaborative study of screening programmes in eight countries was performed to estimate the risks of cervical cancer associated with different screening policies. Most of the data came from centrally organised screening programmes. Relative protection was higher in women who had had two or more negative results of screening tests than in those who had had only one negative smear, particularly in the first five years after the last test. There was little difference in the protection afforded by screening every year compared with every three years, but screening only once every five or 10 years offered appreciably less protection. The age of the women did not affect the sensitivity of the test or the sojourn time of the disease (the length of the detectable preclinical phase during which abnormal cytology could be picked up if a smear were taken); invasive cancer in women under 25 was rare. Centrally organised screening programmes were more effective than uncoordinated screening. Screening programmes should be aimed principally at women aged 35-60 but should start some years before the age of 35, and the intervals between screening should be three years or less.
