Histopathological profile of breast cancer at a tertiary hospital in Malawi: A retrospective cross-sectional study.

Breast cancer is one of the major public health problem in developing countries. In Malawi, cancer of the breast among females is among the top four accounting for 4.9%. The study determined the histopathologic profile of breast cancer in Northern Malawi from July 2013 to June 2018. A record based retrospective cross-sectional study was conducted at Mzuzu Central Hospital. We reviewed 202 histopathological results of breast specimens during the study period. Data was analyzed using STATA version 14.0. Out of 202 clinically diagnosed breast lesions/tumours, 102 (50.5%) were histopathologically confirmed cancerous in nature, and 100 (49.5%) were non-cancerous. Ductal carcinoma was the leading histologic presentation with 68 cases representing 66.7%. Participants in the age group of 70-89 years were 13 times more likely to develop breast cancer (OR 12.66; P-value = 0.001; 95% CI 2.79 - 57.46), compared to those in the age group 10-29 years. The magnitude of breast cancer in Mzuzu Central Hospital, Northern Malawi is alarming (50.5%). Policy makers should emphasise on awareness campaigns for early and routine breast screening, early diagnosis and early treatment.
