Skin

cancer Skin cancer is the most common form of cancer in humans, and is caused when skin cells are damaged by overexposure to ultraviolet (UV) radiation, usually from the sun. UV radiation can also come from tanning beds and other sources. Skin cancer can be deadly if not treated, and early diagnosis is key to successful treatment. There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal and squamous cell carcinomas are generally considered to be less dangerous, while melanoma can be more serious and even deadly if not diagnosed and treated quickly. Treatment for skin cancer may involve topical medication, radiation therapy, or surgery. Prevention is key, and reducing exposure to UV radiation with sunscreen, clothing, and protective eyewear can help reduce your risk.
