I had a small growth that grew fairly quick and was kind of crusty. It didn't look good so the dermatologist removed it and sent it to the lab. That removal healed up real nice but the doctor cut the area open and took samples to check for cancer below the surface. Good news, no cancer but the gash took 5 stitches to sew up. Sucks but better than letting it go and having serious cancer later. Too much sunburn when I was a kid.
