Abstract
BACKGROUND: Breast cancer is the most common occurring cancer in women worldwide. To guide current breast cancer screening program, the level of knowledge about breast cancer should be evaluated. This study aims to ascertain the level of breast cancer knowledge including risk factors, signs and symptoms, and early detection methods, especially mammography screening.Entities:
