Warts and verrucas are benign lumps on the skin caused by the human papillomavirus (HPV) which usually they appear on hands and feet. Warts and verrucas will eventually disappear with time and there is no need to treat them.
You can have warts and verrucas at any age, but they are most common in young adults. Warts and verrucas are benign lumps on the skin and will eventually disappear as the body produces an antibody against the virus. They may take longer to resolve in adults, sometimes years. However, disturbances in the immune system and some medications can slow down or even stop the healing.
