The optimal protection against SCC is three-fold: UV avoidance, UV protection, and examination by your dermatologist. Limit sun exposure all year, not just during the summer. Never use tanning beds or sun lamps. When you are exposed to the sun, be sure to use high-SPF (30 or greater) sunscreen, reapplying every two hours.
Also, don’t underestimate the importance of a broad-brimmed hat to keep sunlight off your face and neck. Finally, schedule regular skin checks with your dermatologist and immediately let them know about any new or changing moles or lesions. SCC is highly treatable when discovered early.
