I JUST noticed a small growth on the outside of my upper left arm. It feels like it's about the size of a small marble. I had a mammogram in July that was negative. I see my OBGYN every 6 months for a breast exam because of a benign breast cyst about 5 years ago. The growth doesn't hurt. I only noticed it as I rubbed my arm. Any idea what this could be?

I think that it would be best if you consulted your OBGYN in person rather than speculating as to what it could be on this site. I know that you will have much more peace of mind if you do that.

I have a big dark spot on my arm it by my elbow it the size of a fifty cent , it get real dry
