Purpose: Breast cancer accounts for over 30% diagnosis and 15% deaths in advanced clime like US. In Nigeria, female breast cancer is adjudged as major cause of mortality and mobility with incidence rate ranging from 36.3% to 50.2% per 100,000 live births. There is no record of study on women breast cancer in Owo Local Government Area of Ondo State. This research aims to determine trends in breast cancer by age and tumor pattern.
Methodology: A descriptive, cross-sectional design was employed. A total of 310 breast biopsies were received, processed and analyzed between 2014 and 2018. Two of the breast biopsies were from male patients and diagnosed gynecomastia. Since the study focused on female breast lesions, 308 of the breast biopsies were considered and treated in the study.
Findings: The findings of the study will be used to determine the onset of age at which women are to access mammography. It will also be used to create awareness of burden of breast carcinoma in the study area. All cases of benign breast tumors accounted for 59.7% of all breast biopsies received followed by 31.2% of Malignant breast tumors, other breast lesions encountered accounted for 9.1%. the peak age brackets for all cases of benign breast diseases was 20-29 while 40-49 for invasive ductal carcinoma. The pre-malignant lesion of atypical hyperplasia was 2.59%.
Unique contributions to theory, practice and policy: Based on the incidences and age distributions, upsurge of benign breast diseases was observed within age bracket ’20-29’ while breast cancer was within 40-49. As a matter of policy, women of age bracket 20-29 should avail themselves of the opportunity of regular breast screening for early detection of lesions that may result into benign breast diseases. Immunohistochemical procedures should be added to the range of testings to allow for molecular characterization of breast cancer.
