There are many different types of warts. Warts can be classified into three main groups, squamous cell, adenocarcinoma and non-adenocarcinoma warts. Squamous cell warts are usually benign and don't require treatment. Adenocarcinoma and non-adenocarcinoma warts have a very high chance of spreading and can affect many parts of the body and pose a huge threat to patients.
Adenocarcinoma (Cataracts) Squamous cell cancer is the most common type of wart, and it is most common in people with light skin and lighter than dark skin. It usually doesn't spread, but can cause problems later in life. It is also caused by sunlight exposure. Non-adenocarcinoma (N.A.) Warts usually don't spread. But in rare cases, non-adenocarcinoma warts can cause serious problems. It is caused by exposure to radiation, chemicals and the sun. Non-adenocarcinoma warts often come back, usually in one year, after a break. It is usually the size of a dime. Non-adenocarcinoma warts are painful, inflamed, and itchy. In addition, there are other problems that can result. The warts often come back again in a different way. There are some warts that can grow very large and stay in the same spot, for years. Other warts can spread and disappear when the warts are not looked after.
