OBJECTIVE: To identify the main sources of information on breast cancer used by women; to determine whether there is an association between the use of specific sources and the education level or income of these women; to determine how women evaluate their own knowledge about breast cancer (self-evaluation); to determine whether this self-evaluation has affected the habit of doing breast self-examination. MATERIALS AND METHODS: Five hundred and thirty-one women, aged 20 years or older, were randomly interviewed in a private hospital in Goiânia, GO, Brazil. RESULTS: Television was pointed out as the main source of information on breast cancer (26.5%) regardless of education level or income, followed by magazines (16.8%), talking to other people (16.2%), physicians (15.8%), newspapers (12.2%), radio (8.4%) and internet (3.9%). A chi-square test indicated association between the four most used sources of information on breast cancer and the education level and family income. CONCLUSION: Interviewed women pointed out television as their main source of information on breast cancer. Eighty-three percent of the women deemed to have average or good knowledge about breast cancer. Women who considered themselves as having good knowledge about breast cancer were more prone to perform breast self-examination at appropriate intervals.

The Breast Imaging Reporting and Data System (BI-RADS™) of the American College of Radiology is a system designed to standardize mammography reports, to reduce breast imaging misinterpretations and to facilitate monitoring of the outcome. OBJECTIVE: To identify the compliance of women and physicians with BI-RADS recommendations in Goiânia, GO, Brazil. MATERIALS AND METHODS: 3,000 women submitted to mammography examinations in a private clinic in Goiânia (January to December, 2002) were evaluated. The mammograms were reported according to BI-RADS classification. Women classified as categories 0, 3, 4 and 5 were followed up by telephone. RESULTS: Women who refused to follow the recommendation: category 0 (11.5%), 3 (13.8%), 4 (28%), 5 (0%). Physician failure to advise the patient to follow the recommendation: category 0 (18.2%), 3 (17%), 4 (20%). Women who complied with BI-RADS recommendation: category 0 (1.8%), 3 (5.7%), 4 (40%), 5 (100%). Contact lost during the follow-up: category 0 (68.5%), 3 (39%), 4 (12%). CONCLUSION: The level of compliance with BI-RADS recommendations was low in categories 0 and 3, and moderate in category 4. About 30% of women classified as category 0 did not undergo additional imaging evaluations either because of their refusal or lack of adequate physician advice.

OBJECTIVE: To identify the characteristics of physicians in the State of Goiás, Brazil, regarding patient management, beliefs, opinions and knowledge about breast cancer. MATERIALS END METHODS: A total of 592 questionnaires were mailed to gynecologists, mastologists and geriatricians. The survey covered the following main aspects: 1 - socio-demographic characteristics (sex, age, year of graduation, private or public practice); 2 - ability to recognize breast cancer risk factors; 3 - implementation of educational activities for the patients; 4 - perception of obstacles to breast cancer screening; 5 - generic questions. RESULTS: The total number of answered questionnaires was 105 (21.2%); 70.5% were male physicians; mean age was 43.9 years (26-70 years); 73.5% had 20 years or less of graduation; 88.6% were gynecologists, 4.8% gynecologists/mastologists, 3.8% mastologists and 2.8% geriatricians; 62.5% were practicing in private and public clinics. Only 13.3% of the physicians recognized the five breast cancer risk factors presented. Approximately 95% of the physicians attended continuing medical education courses in the last two years previous to the survey. CONCLUSION: Breast cancer screening guidelines seemed to be misleading for most physicians. The answers regarding educational activities were sometimes contradictory. The beliefs and opinions regarding breast cancer screening were strongly positive. Insufficient number of equipments and the high cost of the tests were pointed out as obstacles to breast cancer screening.

The Breast Imaging Reporting and Data System (BI-RADS™) from the American College of Radiology is a system designed to standardize mammographic reporting, reduce confounding factors in breast imaging interpretation, and to simplify the management of the final result. OBJECTIVE: To identify how the system is being used, providing information to help the Brazilian College of Radiology to develop strategies to improve its use. MATERIALS AND METHODS: Data were collected in the City of Goiânia, GO, Brazil. Each woman submitted to the examination in the service between January and June, 2003 was asked to provide previous reports and films. Examinations performed between 1/7/2001 and 30/6/2003 were included in the analysis. RESULTS: A total of 104 previous reports done by 40 radiologists from 33 different services were collected for analysis; 77% (n = 80) used the BI-RADS™. From these, only 15% (n = 12) were concise, none followed the recommendations suggested by the system, 98.75% (n = 79) were not in conformity with the lexicon terminology and in 65% (n = 51) there was no reference to pertinent recommendations. CONCLUSION: Although largely used, BI-RADS™ was not recognized as a system designed to standardize the reports and it was used almost exclusively to a final categorization of the exams.

We studied the profile of 2,000 women who were submitted to mammography studies at a public hospital and at a private clinic in the city of Goiânia, GO, Brazil. Data were collected through interviews. The mean age of the women was 49 years. Most women resided in the city, 11.5% had not breastfed whereas two thirds had breastfed for more than 6 months. Hormone-replacement therapy was used by over 20% of the women, of which one fifth had never been submitted to a mammography study. Family history of breast cancer was reported in 13.3% of the women examined at the public hospital and in 7.5% of the women examined at the private clinic. Of these, 28.67% and 33.33%, respectively, had never been submitted to a mammography study before. Screening for cancer was the main cause that motivated the exam. A great number of the interviewed women had not been submitted to a mammography study due to the lack of a medical request, or simply because they considered it unnecessary at the time of request.
