Incidence trends and patterns of breast cancer in Sri Lanka: an analysis of the national cancer database

A gradual decline in the incidence of breast cancer is documented in developed countries especially over last two decades, while in developing countries the incidence continues to rise. We conducted this study to examine trends in incidence of breast cancer in a developing country, Sri Lanka.
