A couple of fews ago I developed what I thought was a bruise on my left hand between my thumb and index finger. It's gotten darker though, and now appears to be two symmetrical flat moles. Then about five days ago, I noticed that I had developed a large round mole on the ring finger of my right hand. I've been wearing a ring on that finger for over a decade so I don't think that could be the result of sun damage. The mole seems to be largeish and seems to have appeared rather quickly. Now I'm also developing some more spots on my right hand, that look like sun spots, except that I'm only 24, use suntan lotion and live a healthy lifestyle. I've been worrying myself sick over these as I've been waiting to get a dermatologist appointment. Any reassurance would be appreciated. Thank you!
