Warts are tumors or growths that occur on the skin because of the keratin component growing too fast. This is brought about by the Human Papilloma Virus, otherwise commonly known as HPV, which is contained in them.
Are warts dangerous? Well, most warts are not dangerous. This is not to say that they are harmless. Other types of warts can be described as potentially dangerous.
In this category are genital warts. They are very well known to be highly contagious and may sometimes lead to cancer. The type of HPV virus that is contained in them attacks the mucosal tissue lining, sometimes leading to cancer. Two examples of cancers that may be brought about this way are cervical and anal cancers.
Warts are also dangerous in that they are very contagious. If your skin comes into contact with warts that are on another person, there are very high chances that you may develop them too. Also, warts are transmittable from one body part to another. If you for example scratched your warts using your finger nails, they are also going to develop on the finger tips.
Warts are also dangerous in that they contain the Human Papilloma Virus, which is not curable. They can disappear by themselves but the virus remains in the body. This largely goes to explain why most of the warts when removed, still grow back.
Warts are also very hard to remove. There are a many complex methods that are used in their removal but none of them is a hundred percent effective. This means that none can guarantee that they are not going to grow back.
Some warts are painful. A good example of such is the verruca that grows on the sole of the feet. The pain comes about when the body exerts its pressure on the feet. It is this pressure that often makes them also grow back, immediately they are removed.
Some warts are so big that when they are removed by surgery, leave large permanent scars. Others are minute and spread over a large body area, making even their removal very difficult.
Once you notice that you have warts, it is important to see a doctor immediately. He or she would be in the best position to analyze them and advise you adequately on the potential dangers they pose as well as on how to treat them.
