Can A Wart Cause Skin Cancer?

Human papillomavirus, or HPV, is well known to cause warts in people. A new study found that some types of HPV, may increase the risk of nonmelanoma skin cancers. A review of blood sample records in Norway and Sweden shows that people infected with a certain group of HPVs that make their home in skin cells were 30 percent more likely to develop squamous cell carcinoma, a type of skin cancer, over a 30-year period than those not infected with this group of viruses.
