Hi everyone. I've found a tiny, hard lump in the lymph nodes in my armpit - very hard to believe it might be cancer, as it is actually tiny. What is worrying me slightly, is that it is on the same side as I had a lumpectomy years ago and then around 10 years ago, I had a mastectomy after 3 separate cancers were found in the same breast.I have no idea what a swollen underarm lymph node feels like, except when I have a cold or whatever, and can feel large round lumps on either side of my haw. This tiny hard nodule is completely different. Any ideas?
