Three Treatments Slow Skin Cancer
Posted: August 29, 2006Acid skin peel, laser resurfacing, and a chemotherapy cream all remove precancerous skin growths and slow -- but patients prefer the peel.
Precancerous growths, small areas of discrete roughness to the skin, come from too much sun, note VA researcher Basil M. Hantash, MD, PhD, and colleagues. Particularly when a person has a lot of them, they tend to become squamous cell carcinomas:.
Doctors often burn off these growths, called actinic keratoses, with liquid nitrogen. But there's evidence other ways of removing them work at least as well.
Also, the other techniques appear to do another very important thing: They slow the development of cancer.
Hantash, of Palo Alto, Calif., and colleagues compared three of these techniques in 24 men. The patients had an average age of 73; all but three had previously had skin cancers removed. Five similar patients served as an untreated comparison group.
