The common wart is caused by HPV virus infection, laser treatment and cryotherapy are common means of treating the common wart, each has its own advantages and disadvantages, there is no clear distinction between the good and the bad.
1. laser treatment: laser treatment is to burn the warts off by means of a laser light. The laser light spot is smaller, the treatment is more accurate, and the laser has the function of electrocoagulation, but also can play a role in stopping the bleeding. The laser can also be used to stop bleeding. However, the laser is more painful and prone to recurrence.
2. Freezing treatment: Freezing treatment is to use a cotton swab dipped in liquid nitrogen, using the low temperature of liquid nitrogen to damage the warts. The liquid nitrogen freezing is less painful and less likely to leave a scar. However, liquid nitrogen freezing area is relatively large, low precision, may cause some damage to the surrounding normal tissue.
It is recommended that patients do a good job of protection after treatment, try to choose loose and breathable clothing, minimize friction, to prevent the triggering of infection.
