Aim: To study anaemia in newly diagnosed breast and gynaecological malignancies in pre and post menopausal females. Material and methods: We conducted a prospective, cross sectional and observational study of anaemia in new ly diagnosed breast and gynaecological malignancies in pre and post menopausal females. Association between categorical variables was calculated using Chi Square or Fischer Exact test. Association between continuous vari ables was calculated using Student T test. Results: Among 55 female patients taken up for the study, 24 were premenopausal and 31 had reached menopau se. The prevalence of anaemia in breast (51.6%) and gynaecological (45.1%) malignancies were significantly hi gher in postmenopausal females. Bleeding was most commonly found in gynaecological malignancy females, w hile it was significantly absent in breast carcinoma females. Microcytic anaemia (Iron deficiency or blood loss) was the commonest type in the study subjects (50.9%) followed by normocytic (Anaemia of chronic disease) an aemia (23.6%). Conclusion: 31 among 55 female patients taken up for the study had reached menopause. The prevalence of ana emia in breast and gynaecological malignancies were significantly higher in postmenopausal females and bleedi ng was most commonly found in gynaecological malignancy. Microcytic anaemia was the commonest type in th e study subjects followed by normocytic anaemia
