Skin Cancer Scare

So today I'm going to the doctors to be checked for skin cancer. Recently I've been getting these blackish bumps in random places on my body like my stomach and legs. They seem to be a small form of skin cancer, but I wont know for sure until after I see the doctor. My mom thinks its from fake tanning, which I only do before dances. The scary thing is that it runs in my family, so I'm a little nervous. I even googled the symptoms and treatments because I'm so scared. Hopefully everything goes okay.
