Breast lump constitutes a significant population affecting all ages and ethnic groups. They are a cause of concern to patient and hence are reported early in OPD. BBD is a complex of reactive/inflammatory lesions, proliferative and fibroepithelial lesions some of which mimic malignancy clinically or mammographically and poses diagnostic dilemmas to both clinicians and pathologists. FNAC, Histopathology and other ancillary techniques are essential for exact pathogenesis. This study was carried out with the aim to study Incidence of Benign and Non neoplastic breast diseases out of total breast lumps presenting in OPD, 2.Frequency of individual benign breast disease 3. Distribution with age and sex. This is an observational type of study conducted in department of pathology, SMS medical college, Jaipur over period of one year (1st January 2016 to 31st December 2016). Out of total 469 cases received for histopathology, 326(69.50%) were found to be benign lesions. Commonest benign lesion was fibroadenoma 160 cases (52.45%) in females and gynaecomastia 39 cases (11.96%)in males followed by and granulomatous lesion, 23 cases ( 0.8%) and fibrocystic change 20 (0.6%). BBD accounts for 70 to 80 % in Indian population as seen in different studies. In our study, benign breast diseases comprised greater proportion (69.50%) than malignant disorders. Since, the prognosis and treatment of benign and malignant lesions are wide apart, and some proliferative benign lesions tend to convert into malignancy, so it is necessary to identify these lesions at the earliest and initiate appropriate treatment surgery or medical.
