Non-melanoma skin cancers are the most common types of skin cancer, primarily including basal cell carcinoma and squamous cell carcinoma. These cancers usually develop in the outer layer of the skin and are often caused by excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds. They tend to grow slowly and are less likely to spread to other parts of the body compared to melanoma. Early detection and treatment are crucial for non-melanoma skin cancers, as they can often be effectively managed with surgical removal or other therapies. Regular skin checks and protective measures, such as using sunscreen and wearing protective clothing, can help reduce the risk of developing these cancers.
