I am 33 years old and have a moderate amound of breast cancer on my mother's side. My general surgeon and I have found a mass in my right breast. He said that it was very asymmetric to the left breast, and that it was of concern to him. We did a core biopsy, and it came back negative for cancer. I have also had a mammogram and an ultrasound done, the results were no abnormal findings. My question is how can I have a palpable mass that both the surgeon and I can feel and it not show up on mammogram or ultrasound? What type of tissue can that be? Also, what is it about asymmetry that is spooking my doc so much? I take it that is a bad thing? Next week, I am having an MRI as a last resort to try to keep me out of surgery for excisional biopsy. I had a fibroid tumor removed in March, and do not want to have it again.
Sorry to sound so green, I am just so uneducated, I thought you nice people may be able to shed some light on my situation.
Thank you for any response
