Skin cancer is a type of cancer that affects the skin cells, typically as a result of exposure to ultraviolet (UV) radiation from the sun or tanning beds. Skin cancer is the most common type of cancer in the United States and is usually preventable.
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell carcinoma and squamous cell carcinoma are the most common types and are usually less aggressive, while melanoma is less common but more dangerous as it can spread to other parts of the body.
Risk factors for skin cancer include fair skin, a history of sunburns, a family history of skin cancer, and exposure to UV radiation from the sun or tanning beds.
The symptoms of skin cancer can vary, but typically include a new or changing mole, a sore that does not heal, and an itchy or painful area on the skin.
Diagnosis of skin cancer usually involves a skin biopsy, in which a sample of the affected skin is removed and examined under a microscope.
Treatment for skin cancer depends on the type and stage of the cancer, but may include surgery, radiation therapy, and chemotherapy.
Prevention of skin cancer involves protecting the skin from UV radiation by wearing protective clothing, using sunscreen with a high SPF, and avoiding tanning beds. Additionally, it is important to perform regular self-exams to check for any new or changing moles, and to see a dermatologist if you notice any unusual skin changes. Early detection and treatment of skin cancer can greatly improve the chances of a successful outcome.
