I have had a suspicious looking mole on my chest for almost 3 years that I thought was just a regular brown mole and thought nothing of it. I realize now, it was most likely from tanning and at some time grew there.. Recently it began pealing skin and looked bubbly around the edges. Just went to the Dermatologist today- was very concerned as the Dr. said it looks like a skin cancer, assuming basal cell carcinoma and did a biopsy and cut it off. I have to wait 2 weeks for a final answer and what kind of cancer??. I've been scared right now thinking #1 because it was left go for 3 years, does that mean cancer could of spread? or I will never get rid of the cancerous cells. #2 Can this mole come back again in the same region? #3 I was always told once someone has a cancer or a growth and a Dr. cuts into it, once it hits the air, it can spread. Is this true? When I was told skin cancer, my mind started racing. I know it sounds ridiculous. I had many questions to ask the Dr. but, she was very busy from room to room. #4- of all the regular Dr. visits at my primary dr. and blood work I've had, all panels and cbc profile have come back normal. If someone has a skin cancer- does it not show in blood work? Thank you!
