I just had a sterotactic biopsy 7 days ago on my right breast and, although I had little or no pain in my breast thereafter, I am now having a lot of pain in my lymph nodes on that side. Two days ago I was called by my primary care doctor and told that the lump in my breast is cancer. I've had no contact from the radiologist and I have to wait for a week for a surgical consult for a lumpectomy. Tomorrow I am going to call my regular physician and see about getting in to see him. If he enlightens me regarding the pain under my arm, I willl post to you again.
Lymph nodes can become enlarged for several reasons; one being an infection somewhere in the body. You might ck. with your Dr. or whomever did your biopsy about the swollen node. Regards ...
