Browsing: Skin Cancer

Skin cancer is the most common form of cancer globally, primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. It occurs when mutations arise in the DNA of skin cells, leading to uncontrolled cell growth. The three main types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Basal cell and squamous cell carcinomas, collectively known as non-melanoma skin cancers, are highly treatable and usually not life-threatening. Melanoma, although less common, is the most aggressive type and can be deadly if not detected early. Symptoms vary depending on the type but can include new growths, changes in existing moles, sores that do not heal, and patches of skin that bleed or become scaly. Prevention strategies include limiting sun exposure, using sunscreen, and wearing protective clothing. Early detection through regular skin checks plays a critical role in effectively treating skin cancer, particularly melanoma.
