More importantly than the size is the location and how much tissue it has invaded. As I had mentioned if it is in an area with a lot of cartilage such as an ear or nose it can be tricky. But there is a procedure called mohs surgery which is very effective if it goes deeper or invades a lot of surrounding tissue. Most skin cancers (SCC & BCC) are removed without incident, heal and never cause a problem but follow up is important once skin cancers are diagnosed as you have a greater propensity to develop other skin cancers, plus healing of the area is important.
