TREATMENTS Attacking cancers
Several therapies are currently used to treat precancerous lesions and early-stage skin cancers.
Normally, actinic keratoses (precancerous growths) and superficial basal cell cancers can be frozen off with liquid nitrogen, though the treatment can cause several weeks of redness and irritation.
Repeated applications of several creams, such as Carac, Efudex and Solaraze, can remove keratoses patches, too.
Retinoid acids, such as the acne medication Retin-A and Aldara, a topical lotion to combat genital warts, may also be used to eliminate keratoses lesions. These creams work by causing the abnormal cells on the top layer of skin to die off.
