Skin cancer is a disease that involves the growth of abnormal cells in the skin tissues. It is the most common type of cancer in the United States. Skin cancer occurs when skin cells are damaged by ultraviolet (UV) radiation from the sun or tanning beds, which can cause mutations in the DNA of skin cells. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
-
Basal cell carcinoma: This is the most common type of skin cancer, accounting for about 80% of all cases. It usually appears as a small, shiny bump or a red, scaly patch on the skin.
-
Squamous cell carcinoma: This type of skin cancer is less common than basal cell carcinoma, but it can be more aggressive. It often appears as a firm, red nodule or a flat lesion with a scaly, crusty surface.
-
Melanoma: This is the most dangerous type of skin cancer, accounting for only about 1% of all cases but causing the majority of skin cancer deaths. It often appears as a dark, irregularly shaped mole or lesion on the skin.
The most common warning sign of skin cancer is a change on the skin, such as a new growth or a change in an existing mole or lesion. Other symptoms may include itching, bleeding, or pain in the affected area. It is important to check your skin regularly for any changes and to see a doctor if you notice anything suspicious.
Prevention of skin cancer involves limiting exposure to UV radiation from the sun or tanning beds, wearing protective clothing and sunscreen, and avoiding outdoor activities during peak sun hours. Early detection and treatment of skin cancer can increase the chances of successful treatment and cure.
