I found a breast lump (semi squishy, size of grape, movable) in my right breast about a month ago. I have implants that have been in for 17 years (half silicone half saline) and I am 40. I also breastfeed my son who is 18 mths. I went to my doctor and he said it did not feel like any cancerous mass he has felt before, but made me appt for Mammogram (1st), U/S, CA125. The lump when pushed can be moved slightly. I also have slight pain in breast and underarm. I have not noticed any lymph node changes, just pain. I would not be so alarmed by this normally, but my grandmother passed away from breast cancer and also had cervical cancer. My mother has ovarian cancer and died at age 46. Could this possibly be cancerous? My shoulder blade hurts as well.
