I am a 21 year old female with several unexplained, hard, painless lumps. When I noticed the first one, I thought it was just a cyst, but now I have 2 in one armpit, 1 in the other armpit, and 3 on my mons pubis. Does this sound serious enough to see a doctor, and, the obvious question, how likely is cancer (family history for several types of cancers).
