long time lump in breast suddenly changes...worried
Hi i wonder if anyone could help me here. Ive had a very small beebee size knot right under the skin in the side of my left breast for about five years now. I was told once its.just a sweat gland and nothing to worry about. Jusy in the past several days it has more than tripled in size and is now very red and sore. Now the size of a marble and also ive been having extremely bad pain in tje shoulder of the same side. Does this sound to be of serious nature?
