Basal cells typically may appear as a pimple-like bump that may bleed and scab. Squamous cell carcinomas may be a flaky red or pink raised area, which also may bleed. Neither one will go away by itself. If left untreated, both may be locally destructive and can occasionally spread. Melanoma is the most serious form of skin cancer.
Advanced melanoma can spread throughout the body and, unfortunately, is often fatal.
It may begin in a mole, or as a brand new area. It typically has an asymmetric shape, an irregular edge or border, dark or black color, and a diameter greater than six millimeters. A yearly complete skin examination by your dermatologist is recommended. Self-skin exams can also be performed in between dermatologist visits. Should any new or concerning areas appear, have them examined by your dermatologist.
