Skin cancer is the most common form of cancer in the United States, and it is important to understand the different types of skin cancer and how to recognize them. Skin cancer is caused by exposure to ultraviolet (UV) radiation from the sun or tanning beds. The three main types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma.
Basal cell carcinoma is the most common type of skin cancer. It usually appears as a small, flesh-colored or pink bump on the skin. It can also look like a red patch or a sore that doesn’t heal. Basal cell carcinoma is usually found on areas of the skin that are exposed to the sun, such as the face, neck, and hands. It is rarely life-threatening, but it can cause disfigurement if not treated.
Squamous cell carcinoma is the second most common type of skin cancer. It usually appears as a firm, red nodule or a flat lesion with a scaly, crusted surface. It is most often found on areas of the skin that are exposed to the sun, such as the face, ears, neck, lips, and backs of the hands. Squamous cell carcinoma can be more aggressive than basal cell carcinoma and can spread to other parts of the body if not treated.
Melanoma is the most serious type of skin cancer. It usually appears as a dark, irregularly shaped mole or a spot on the skin that is different from the surrounding area. Melanoma can spread to other parts of the body if not treated, and it can be life-threatening.
It is important to be aware of the signs and symptoms of skin cancer and to see a doctor if you notice any changes in your skin. Your doctor can perform a skin exam to check for any suspicious moles or lesions. If skin cancer is detected, your doctor will recommend treatment, which may include surgery, radiation, or chemotherapy.
By understanding the different types of skin cancer and how to recognize them, you can take steps to protect yourself from the sun and reduce your risk of developing skin cancer.
