How does the melanin in your skin help prevent cancer?

Melanin does not prevent cancer, it protects against the harmful effects of ultraviolet (UV) radiation from the sun. Melanin is a pigment that gives skin its color, and it acts as a natural sunscreen by absorbing UV rays. While melanin can help reduce the risk of skin cancer, it does not completely prevent it. Overexposure to UV radiation can still lead to skin cancer, even in individuals with high levels of melanin. Therefore, it is important to practice sun safety measures such as using sunscreen, wearing protective clothing, and seeking shade during peak sun hours to minimize the risk of skin cancer.
