Background: Breast masses cause more anxiety for the patients. This study was undertaken to know the spectrum of benign breast lesions with their age of occurrence. Benign breast lesions are more common than the malignant ones. Timely and accurate diagnosis with treatment will alleviate anxiety to the patient. Methods: This study was carried out in a tertiary hospital of north Karnataka region for a period of five years with one and a half years of prospective study. All histopatholgically proved benign breast lesions and inflammatory lesions were included in this study. Results: Of the 600 cases of breast lesion in five years study, slightly less than three fourths of the cases were benign lesions. Of these fibroadenomas formed nearly three fourths of the cases and the remaining were fibrocystic disease, inflammatory and miscellaneous lesions. Conclusions: This study emphasizes that benign breast lesions are heterogeneous group of lesions including inflammatory lesions, neoplasms, non proliferative lesions, proliferative lesion without atypia and prolifertive lesions with atypia. Some of these lesions are a risk of cancer, such patients need a follow up with sonomammography.
