What is Skin Cancer

Skin cancer is a type of cancer that develops in the skin cells. It occurs when the skin cells undergo abnormal growth and multiply uncontrollably. The main cause of skin cancer is exposure to ultraviolet (UV) radiation from the sun or tanning beds. There are three main types of skin cancer: 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, shiny bump or a pink growth on the skin. It rarely spreads to other parts of the body.

Squamous cell carcinoma is the second most common type. It often appears as a red, scaly patch or a sore that doesn't heal. It can spread to other areas if left untreated.

Melanoma is the most dangerous type of skin cancer. It can develop from existing moles or appear as a new, unusual growth. Melanoma can spread to other organs and is responsible for the majority of skin cancer deaths.

Early detection and treatment are crucial for successful outcomes. Regular self-examinations and professional skin checks can help identify any suspicious changes in the skin. Protecting the skin from UV radiation by using sunscreen, wearing protective clothing, and seeking shade can significantly reduce the risk of developing skin cancer.
