Prevalence of Benign Breast Disease and Risk of Malignancy in Benign Breast Diseases

Abstract

Introduction: Woman breast is a dynamic structure undergoes proliferative changes during reproductive period and changes of involution occur in perimenopausal period. Benign breast disease is most common problem in woman. Majority of them require treatment in their life time. Benign breast disease constitutes a heterogeneous group of lesions; include developmental abnormalities, inflammatory lesions and neoplasms. Benign lesions are likely to turn malignant, it is a major concerned to patient as well as clinician, aim of a clinician is to rule out breast cancer since, most benign lesions occur in cancer age group and some of them mimic as carcinoma. Material and methods: Present study is a retrospective/prospective study, carried out in the department of MediCiti Institute of Medical Sciences. We had come a crossed 100 benign breast neoplasms out of 145 breast cases admitted during the said period. Out of which 70 cases were fibro adenomas, followed by 20 fibrocystic diseases and 8 phyllodes tumour and one adenomyoepithelioma and one plasma cell mastitis. Fibro adenoma was most common benign tumour in our study followed by fibrocystic disease and phyllodes tumour of the breast. Out of 20 cases of fibrocystic disease, one was reported as carcinoma and out of 8 phyllodes tumour 2 were reported as malignant. Among variants of fibro adenomas, two giant fibro adenomas, one juvenile fibro adenoma, and one lactating adenoma we had come a crossed. USG breast was initial aid of diagnosis followed by mammogram. FNAC was initial confirmatory diagnostic aid followed by excision biopsy. Treatment: All the lesions were surgically excised. Local excision was done in all fibro adenoma. Wide local excision was done in small sized phyllodes tumour and simple mastectomy was done in large recurrent phyllodes and adenomyoepithelioma. Wide local excision to segmentectomy was done in case of fibrocystic disease of the breast.
