Medical dermatology
Actinic Keratosis (Pre-Cancer)
Treatment of rough, scaly pre-cancerous spots from sun damage — cryotherapy, topical field therapy, or photodynamic therapy to prevent progression to skin cancer.
Field treatment vs. spot treatment
Individual AKs can be frozen with cryotherapy. When you have many AKs on the face, scalp, or arms, field therapy treats the entire sun-damaged area to prevent new cancers.
Prevention
Daily SPF, sun-protective clothing, and regular skin exams — especially critical in Miami.
