Basal Cell Carcinoma
Basal cell carcinoma—the most common form of skin cancer—begins in the basal cells, the bottom layer of the epidermis.
Melanoma, or malignant melanoma, is a serious skin cancer that occurs when the DNA in certain skin cells becomes damaged.
Squamous Cell Carcinoma
Squamous cell carcinoma starts in the middle and outer layers of the skin, and while usually not life-threatening, it can be very aggressive.
