I noticed that there are 2 lumps on both sides of my breast. one is big and one is little, however they are movable. When my doctor found out about it, she said that she feels comfort about the fact that they are movable. She also said by me being very young, it may be something else than cancer....( possibly fibroids). I don’t have a history of breast cancer in my family either. does anyone know what this possibly can be or have ever experienced it.
