Plantar warts may grow back after laser treatment because the laser may not have completely destroyed the warts at once, and the residual virus may grow back into warts.
Plantar warts are benign proliferative lesions of the skin and mucous membranes caused by human papilloma virus infection. Laser therapy is a common treatment for this condition, utilizing the energy of the laser to destroy the warts. However, because the warts may not be destroyed in their entirety at one time, some of the virus may remain, leading to a reoccurrence of the warts, which may require multiple treatments.
The treatment of plantar warts also includes cryotherapy, medication and surgery, which should be chosen according to the specific condition.
It is important to keep the area clean after the laser procedure to prevent secondary infections.
