Fluorouracil
"I'm a 57 year old former sun worshipper. I'm 2 1/2 weeks into 4 weeks of treating squamous cell and basal cell carcinoma on my legs, and actinic keratosis on my face, applying fluorouracil twice per day. I'm covering the spots on my legs with micropore tape. After the fluoroucil has been on my face for 45 minutes, I cover my face with Aquaphor to ease the crusting and dryness.  I'm anxious to see the end result.
