Knot under right arm
I have a small knot under my Right arm that has been there for about two weeks.Ive had alot of Benign cysts under my left arm before.Never had none under the other arm before. I know this is not a cyst because its not sore at all.What do you think .Should i be concerned?
You should certainly get this checked out. It may be nothing, but breast tissue does extend under the arm and lymph nodes are present under the arm. Cancer can occur in this site.
