Fibrocystic change?: Any breast lump or thickening mass of tissue on the breast could be breast-cancer. You need to be seen in person for an exam and possibly imaging. You should be seen right away. One in eight women in the USA get breast-cancer so don't take any chances. There are other things such as fibrocystic change. Best wishes!
