Lymph Nodes in Bicep area of arm?

Hi:

I have what appears to be a couple of little lumps in the bicep area of my left arm. I had HER2 breast cancer in my right breast with one node positve in 1/04 had a mastectomy and removal of 13 nodes. My surgeon said it is probably just fatty tumours but I am worried. Have any of you noticed small firm lumps in your bicep area on one arm and not the other?

Hi Barbara- My left arm had little bumps but that is the side that I had my mastectomy. After massage therapy for lymphedema they went away.Take Care- Cathy
