Do you have melanoma?

is melanoma curable. i remember back when i was in 8th grade i had a mole the size of the top of a pencil eraser on my wrist. the doctor removed and told me it was melanoma but htat he had removed the cancer cells. now i have a what looks like a freckle on my lower abdomin but it is getting a tad bit bigger each maybe every 3 months. it started of tiny, now it looks like a beauty mark. this is what happened with the mole on my wrist. does melanoma mean i have skin cancer? is this cancer curable?
