Preventing basal cell and squamous cell skin cancers largely involves minimizing exposure to harmful UV radiation. This includes wearing protective clothing, seeking shade during peak sun hours, and applying sunscreen with a high SPF regularly. Additionally, avoiding tanning beds and sunlamps can significantly reduce the risk of developing these types of skin cancer. Routine skin examinations by a healthcare professional are also essential for early detection and intervention. By adopting these preventive measures, individuals can mitigate their risk of developing basal cell and squamous cell skin cancers and maintain skin health.
