I have had a mole on my left side for as long as I can remember. It got checked several years ago when I was a preteen (I'm 21 now), but has grown since then. In September, I noticed a small dark mole had popped up by it and checking my other moles, I found a new large mole on my right side as well. The original mole on the left side has a dark spot in it and the mole on my right side has a dark sized circle on the end of it as well. It almost looks like a new normal round mole grew in it. Two nights ago I woke up and the mole on my left side was bleeding and bumped up. It has been hurting kind of like a burn does and scabbed over since then. I don't go to tanning beds and haven't had a tan in probably 3 years. I only have had a sunburn once in my life when I was 14 on my nose. I find it kind of weird that it is a place that is almost always out of the sun that would get any sort of warning signs of cancer? I was just wondering if this was something to be worried about. Thank you.
