Background: Disease pattern varies in different parts of the world due to differences in interactions of prevalent environmental and other factors. The aim of this study was to evaluate the pattern of admissions and incidence of breast cancer at the Rivers State University Teaching Hospital from January 2024 to December 2024.

Materials and Methods: A retrospective observational study was done among admitted breast cancer patients using admission registers and records from the cancer registry, and data obtained was formed into tables and analysed using the Microsoft Excel Spreadsheet.

Results: There were 120 newly diagnosed cases of breast cancer in the year 2024, out of which 116 were female breast cancer. Patients aged 40 – 59 years were mostly affected (n=65, 54.1%), followed by 60-79 years (n=27, 22.5%), and 20-39 years (n=24, 20%). Out of the 500 female surgical ward admissions, 77 (15.4%) were due to breast cancer. Stage IV breast cancer disease comprised 42 (54.5%) of all breast cancer admissions, followed by stage III disease (n=34, 44.2%). Female breast cancer incidence was 209.5 per 100,000 adult population and the institutional incidence of breast cancer therefore was 144.09 per 100,000 adult population. Out of the 120 new cases of breast cancer seen, 33 patients (27.5%) died, and breast cancer mortality was 39.6 per 100,000 adult population in year 2024.

Conclusion: Rising number of breast cancer cases was observed. Breast cancer accounted for more than a sixth of female surgical ward bed occupancy, and metastatic breast cancer was the most common. Action is needed from relevant governmental and non-governmental agencies to stem the rising tide.
