what are the odds that a lump (2) in the breast (left side) which is solid, doesn't move, and contains calcium deposits, cysts, and fatty tissue is malignant? I just turned 31 this month. It doesn't usually hurt only past month during menstruation. One of the months formed later than the other by the way. Also glands in neck front and back swell a lot lately. The glands on the left side of neck have not completely gone down.
