Final answer:
Skin cancer is a disease in which skin cells grow out of control due to excessive exposure to UV light. The most common forms of skin cancer are basal cell carcinoma and squamous cell carcinoma, which occur on sun-exposed areas of the body. Melanoma is a less common but more dangerous form of skin cancer that can develop anywhere in the body.
Step-by-step explanation:
Skin cancer is a disease in which skin cells grow out of control. It is primarily caused by excessive exposure to UV light, which damages DNA. The most common form of skin cancer is called basal cell carcinoma and it usually occurs on areas of the skin that are frequently exposed to UV light, such as the face and neck. Another form of skin cancer is called squamous cell carcinoma which can also develop on sun-exposed areas of the body. Additionally, melanoma is a less common but more dangerous form of skin cancer that can develop anywhere on the body, even in areas not exposed to UV light.
