How are you? Breast pain can also be caused by hormonal changes, inflammation or infection. The risk for breast cancer increases with personal or family history of breast cancer, early menarche, previous chest radiation or hormone therapy, among others, ( http://www.cancer.org/Cancer/BreastCancer/DetailedGuide/breast-cancer-risk-factors ). If the pain persists, it is best that you have this checked by your doctor for proper evaluation. Take care and do keep us posted.
