We have been so stressed by coronavirus that whenever we hear the word “virus,” we likely first think about it. This virus caused a global pandemic and has been the sole reason behind so many tragic deaths. Before this virus entered our liver, we would probably associate a virus with catching cold. But research shows that certain viruses can also lead to cancer. For the uninformed, the hepatitis B virus alone leads to an estimated 360,000 cases of liver cancer globally each year.

Whenever you hear “HPV,” the first thing striking your mind would be some sexually transmitted disease that would cause genital warts and cancerous cells in the cervix, anus or oral cavity. You might also be well aware about the HPV vaccine that was developed for preventing the growing number of HPV-related cancer cases. According to a recent research, it is estimated that nearly 700,000 cancers a year worldwide are attributable to the HPV virus.

How does a Virus Cause Cancer?

We all know that viruses enter cells and do irreversible damage or modify these cells making the cells prone to cancer. The experts of skin cancer treatment Coquille believe that viruses can cause cells to proliferate abnormally, deploying mechanisms that are capable of circumventing or manipulating the immune system, helping the abnormal cells forfeit destruction.

A healthy person’s immune system acts as a surveillance system seeking out abnormal cells, killing the cells before they become cancerous. For example, a healthy immune system is capable of clearing HPVs so that you don’t have any symptoms. The experts of Skin Cancer Treatment Myrtle Point believe that if a person’s immune system fails to cleanse the body, then the virus will reside in the epithelial cells, which is nothing but the line that surfaces of your body. The experts of Skin Cancer Treatment Coquille believe that these viruses act as co-carcinogens and generating clusters of cancerous cells in the cervix, in the mouth and even on the skin called lesions.

It’s important to keep in mind that while HPV is transmitted sexually, it doesn’t just spread during sexual intercourse. HPV is only transmitted through the minute breaks in the upper layer of the skin. The only reason of it spreading during sexual intercourse is that it can lead to genital warts because the rubbing that happens during sexual intercourse causes breaks in the skin there. The fact that HPV lives in the top layers of skin, it can also be transferred outside the bedroom. So now it’s clear that the only reason you might have had a lesion on your hand is because you had a little cut there, and the virus was able to seed there.
