Doctors have many options for treating warts, depending on size, number, location, duration, prior treatments, and patient sex and age, dermatologist Dr. Frank Bures writes. Treatments range from chemicals to burning to freezing, and newer treatments include pulsed dye lasers that cauterize the blood vessels in warts and photodynamic therapy. No treatment works all the time, Bures writes, but most -- including doing nothing -- work 65% to 75% of the time.
