Skin cancer is a type of cancer that develops in the skin cells. It usually occurs due to excessive 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. Early detection is crucial, as melanoma can be more aggressive and spread to other parts of the body. Symptoms of skin cancer may include new growths, changes in existing moles, or sores that do not heal. Regular skin checks and using sunscreen can help reduce the risk of developing skin cancer. If you notice any unusual changes, it’s important to consult a healthcare professional.
