you will not likely find any medical provider who will do that. making a determination about a skin lesion (cancer or not) is more that just the visual appearance. it is the location size elevation etc. and a careful medical history. since you don't know what it is i would not suggest any home removal techniques. get an expert. your regular medical provider or a dermatologist to make this very important decision.
is there an online doctor that would look at my birthmark on my leg to see if i can get it removed? . i want to remove it with a cream or oil but i don't know if it's possible.
