Swelling under the left arm
i have swelling under my left arm it`s only a little painful when you push on it sometimes. i had it for about 2 months now.i go for a mammagram aug . last years mammagram read normal. what could this be.i`m 46
Hard to know for sure, and I certainly think that this should be evaluated. It could be a lymph node. Lymph node enlargement can occur after an infection or trauma to the arm. It could also be a sign of cancer.
