What is Skin Cancer (BCC/SCC/Melanoma)?

Skin cancer is the abnormal growth of skin cells, most commonly caused by ultraviolet radiation. Basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) are the most common types, typically slow-growing and highly treatable when caught early. Melanoma is less common but more aggressive, with a higher risk of spreading if not treated promptly. Early detection significantly improves outcomes for all types.
