Basal cell carcinoma, squamous cell carcinoma, and melanoma are all common types of skin tumors.

Basal cell carcinoma is the most common type of skin cancer, accounting for about 80% of all cases.

Melanoma is the most serious type of skin cancer, as it can spread to other parts of the body and be fatal if not treated early.

Exposure to ultraviolet (UV) radiation, genetics, and a weakened immune system can all contribute to the development of skin cancer.

A new or changing mole, a sore that doesn't heal, and a scaly or crusty patch of skin can all be signs and symptoms of skin cancer.

The treatment for skin cancer depends on the type and stage of the cancer, but may include surgery, radiation therapy, chemotherapy, or a combination of these treatments.

Limiting exposure to ultraviolet (UV) radiation, wearing sunscreen, and avoiding tanning beds can all help to prevent skin cancer.
