What is the connection between HPV and cancer?

Human papillomavirus, or HPV, is actually a group of viruses that number more than 100. Some types cause warts that normally affect hands and legs, while others cause genital warts or mouth and neck infections. There is a link between HPV and cancer, because some HPV types, known as high -risk, may lead to cells to change and become abnormal, increasing the risk of becoming cancer. High risk HPV infections are a form of sexually transmitted diseases and are transmitted from one person to the other by direct skin contact. HPV infection may increase the risk of cervical cancer development, as well as mouth and neck cancer, penis, vagina, vulva and rectum.

Although HPV and cancer are connected, many people are infected with HPV and most of them do not become cancer. Instead, the infection disappears on its own. HPV types that cause verruky and genital warts are described as lowcell changes in the same way as high -risk HPV. HPV types 16 and 18 are most often associated with cancer and are expected to cause approximately 70 percent of all uterine cancer. While high -risk HPV infection increases the chance of developing cancer, risks can also be increased by smoking or factors that reduce body immunity, such as AIDS.

The main type of cancer associated with HPV, cervical cancer can be prevented to some extent by regular testing for cervical screening or paints. These tests detect changes in cervical cells that may be caused by HPV infection. When abnormal cells are discovered, an investigation known as colposcopy can be carried out where the cervix is ​​perceived closer. Sometimes the tissue sample is considered to be deeply abnormal cells extend into the lining of the cervix. If necessary, an abnormal area can then be chIrurgically removed using a heated wire loop.

Research between HPV and cancer has led to the discovery of how HPV causes precancerous changes in cells. Although these changes cannot yet be prevented, the development of HPV vaccine can help people prevent people from getting infected in the first place. There is currently a vaccine for adolescent girls that protects against infection with HPV types 16 and 18, and hopes that it will lead to fewer cases of cervical cancer. Future studies of the relationship between HPV and cancer can lead to vaccines that can treat those who are already infected with HPV.
