kin cancer is the abnormal growth of skin cells, often caused by overexposure to ultraviolet (UV) rays from the sun or tanning beds. The three main types are basal cell carcinoma, squamous cell carcinoma, and melanoma, with melanoma being the most dangerous. Early signs include unusual moles, skin lesions, or changes in texture or color. To protect yourself, apply broad-spectrum sunscreen, wear protective clothing, and avoid prolonged sun exposure. Regular skin checks and prompt medical attention can significantly improve outcomes. Stay informed and take proactive steps to safeguard your skin.
