Human Papilloma Virus is linked to the Head and Neck Cancer
The most common cancer known to be caused by Human Papilloma Virus, or HPV, is the cervical cancer. Recently, the head and neck cancers caused by this virus are becoming more common than cervical cancers. This virus is known to be transmitted through sexual contact. For about 100 different strains are present in your body like the skin, genitals and mouth. Through the years, this virus has been studied to trace its route and treat it. So far, identification of the strains are the farthest that research has discovered.
How virus attacks cells
Unlike bacteria which can exist and proliferate on its own viruses on the other hand need host cells to thrive. This is why they are parasitic in nature. There are no viruses that are not harmful. In comparison to bacteria, you can still find good bacteria which gives benefit to the body and to the environment. With viruses, they are all the same, parasites.
Generally, virus work this way:
- It attaches to a host cell. Any type of cell will do.
- It inserts its DNA to the host cell. At first, the host cell acts like a normal cell. It just sits there until the proliferation of the virus begins.
- New kinds of enzymes are produced because of the virus is the one controlling the cell activity.
- New generation of virus is produced. When the certain number is reached, the cell membrane disrupts and the viruses attach to other normal cells. The invasion to other cells works like a cycle.
The virus can blind the normal cell because of the protein coating it contains. The protein looks the same as the protein of the normal cells. This is their route of attachment.
Gum inflammation, head and neck cancer- Are they linked?
Mini Tezal, a doctor in oral dentistry wanted to establish a theory that says HPV that causes persistent inflamed gums is the one responsible for the head and neck cancer. According to him, he found HPV strain 16 or HPV-16 in the head and neck tumors. He got the data from 50 cancer patients out of 124 that he surveyed. He was interested in this topic because there is an increase occurrence of esopharyngeal cancers despite of the decrease in tobacco use among the Americans. He wanted to uncover the culprit behind the spread of the sickness. And, the first step he formulated is to look into the mouth which is the portal of all that gets inside your body.
Researchers at John Hopkins Hospital say that 80% of the oropharyngeal cancers are due to infection from this HPV virus and it has nothing to do with the individuals who smoke or don’t smoke.
Is there any tests for oral HPV?
There are no tests at this time for pre-cancerous changes occurring in the head and neck region from HPV viral infections, like there are tests done by the gynecologist for women to detect pre-cancer due to HPV virus. Scientists are still working on this.
