I educate all patients on proper sun protection, as we know that cumulative lifetime sun exposure increases the risk of skin cancers. I recommend wearing a broad spectrum sunscreen, (ideally mineral based) with an SPF > 30 every day, and reapplying it every 2-3 hours, in addition to seeking shade and wearing protective clothing.
A thorough examination of the skin is performed at least annually to diagnose abnormal lesions and prevent evolution into skin cancer. Atypical moles and suspicious lesions are removed and submitted to a lab for microscopic evaluation. If required, further treatment is performed.
