This being the second time this has happened i have become concerned. I noticed two raised pieces of skin about the size of bbs on the very upper part of my left thigh on the inside. I am 21, lift weights but other than that i am not very active. I am concerned that it might be some kind of skin cancer but hopefully i am just exaggerating. they don't hurt, even when isqueeze them, arent like zts or blackheads and are right next to each other, iwould appreciate any kind of help. thanks
