I'm so scared about what the doctor will tell me!!! Please help me here?

Sweetheart, with all the cancer scares, I can understand where you're coming from, but this doesn't look like cancer. My dad had skin cancer and it was worse looking than that. I know everyone is different but you said yourself that it got smaller. That's a good sign. When a mold, or birthmark, or wart changes in ways like they get crusty, change color, size (usually bigger), or become raised, then you have some concern. This is flat, small. My youngest daughter is a hypochondriac too. She's 35 and she realizes that she over reacts. It's OK to be scared. The Dr will put your mind at ease and I hope I did too. Good luck and God bless.
