Most skin cancers are treated in the physician s office using local anesthetic. Warts are contagious. They usually appear three to eight weeks after exposure to the virus. Some people, having developed an immunity, do not catch the disease, but in other instances, one will find numerous cases in which there are several people in the family with warts. Contagion occurs by direct contact.
Some people develop an immunity after contracting warts resulting in spontaneous healing.
This is caused by the natural body defense system, but does not occur in all people. All professional treatment is aimed at destroying the virus. Several types of treatment are used for this, such as excision, acids and freezing. The kind of treatment employed depends on the size, location and abundance of the warts. With any of these methods, several treatments may be required.
