BACKGROUND: Breast cancer accounts for 14% of all cancers in Indian women, that can occur at any age. Cancer survival becomes more difcult in higher stages of tumour, hence in order to improve the survival of affected persons, early diagnosis of breast cancer is critical. METHODS: Retrospective study of 48 mastectomy specimens with relevant clinical details and respective H&E stained slides were reviewed. CONCLUSION: This review showed that occurrence of Invasive Breast Carcinoma(IBC) peaks in the age group of 41-50years (35.4% ) with right and left breast being affected equally in the ratio of R:L – 1 : 1. Most of the IBC (91.6%) were of No Special Type (NST), with 75% of tumours were of Histological Grade II. 58.3% of tumours were of tumour stage T along with lymph node involvement in equal number of cases.
