Breast Carcinoma in a Nulliparous Woman: A Case Report

Breast carcinoma is a heterogeneous malignancy with multifactorial etiology involving genetic, hormonal, environmental, and reproductive factors. Nulliparity is a recognized risk factor due to prolonged exposure to unopposed endogenous estrogens. This case report presents a 42-year-old nulliparous female diagnosed with right-sided breast carcinoma, who presented with a palpable breast mass and ipsilateral axillary lymphadenopathy. Clinical examination and imaging revealed a well-defined, mobile lesion in the upper inner quadrant of the right breast, classified as BIRADS III. Given the tumor size and nodal involvement, a Modified Radical Mastectomy (MRM) was performed under general anesthesia. Histopathological and receptor status evaluation will guide further management, including adjuvant therapies. This case underscores the importance of recognizing nulliparity as a significant risk factor and highlights the need for individualized, multidisciplinary management strategies in breast cancer.
