Skin cancers: Cancer is due to genetic changes in previously normal cells. It usually requires several sequential genetic changes to occur before the cell develops the capacity to invade or metastasize. Some people with the same baseline genetic disposition may develop the same cancer, but it usually requires other stimuli to occur. Long answer to say, probably not. Most skin tumors have external promoters.
