I'm 17. I've been directly exposed to the sun lately (about 3 days in a row). I just noticed the lump this morning, and being a hypochondriac, I'm worried. Could it be skin cancer caused by being in the sun directly?

Well you go to your doctor's office and have the lump diagnosed, cause we don't do it here for a lot of obvious reasons. Skin cancer is normally exposed, bloody skin and itchy, or a wart that is red around the outside and sore. So go figure, go to your doctor.

It's either a pimple or a cyst. You can be sure it's not skin cancer.

The best thing to do is to go and see your Doctor who will give you a correct diagnoses.Otherwise you will still worry no matter what anyone tells you... only your Doctor will know for sure.
