Mammography Role in Screening of Breast Cancer
OBJECTIVE: This study was done to determine role of mammography in screening of breast cancer.
STUDY DURATION AND DESIGN: This study was done in a period of six months from July 2017 to December 2017.
PLACE OF STUDY: This study was done in radiology department of Bahawal Victoria Hospital Bahawalpur, Pakistan. A tertiary hospital located in the center of city.
PATIENTS AND METHODS: There were 935 houses selected from the city of Bahawalpur randomly within the radius of 10 kilometer. These all homes were visited and one female from each house was invited for mammography in Victoria Hospital Bahawalpur radiology department. Out of 935 houses 900 sent their females for the test and 35 refused for this. Total 900 women were undergone the procedure. Their data was documented such as age, number of children, family history of malignancy or breast cancer, education level and marital status etc. In which patients malignancy was suspected they were undergone FNAC to confirm the diagnosis. Which patients showed benign conditions they were referred to relevant specialty for the treatment. Informed Consent was taken from these ladies for including their data in the study. Age range of these patients was 35-55 years with mean age of 40.5 years. Results were calculated in the form of frequencies and numbers and expressed via tables and charts. Data was composed on Microsoft office version 2017.
RESULTS: There were 900 female which were undergone mammography. Out of them 710 had normal findings and, 82 showed fibrocystic changes, 10 females had fibroadenoma, 31 had palpable lymph nodes, in 4 cases dysplasia and ductal ectasia was found. Out of 900 females only 27 showed malignancy. In these 27 females FNAC was performed and sample was sent for histopathology to confirm malignancy. There were 110 females with age 35-40 years, 171 with 41-45 years, 114 with 46-50 years, 206 with 51-55 years and 109 females were having age of more than 55 years. It was seen that most of the females were with age 40-50 years. Mostly malignancy was common in those females which were having age above 45 years. In young age malignancy is uncommon. In these females fibrocystic changes were common. Some of them showed just lymph nodes enlargement and no other changes were found. Out of 27 cases with suspicion of malignancy on mammography 21 confirmed carcinoma breast on histopathology. Positive predictive value was 74%.
CONCLUSION: Mammography is a very useful screening test for breast cancer with significant high positive predictive value. It is cheap test and easily performed. This technique can be used on mass population to determine prevalence of breast cancer.
