Relationship Between Infection and Cancer

For many years researchers have done studies on cancer including how they develop in the body and the effects the cancer has throughout the body when it spreads. We know that cancer is developed when cell growth goes out of control but recent studies have shown there may be a link between infection and cancer. Certain virus infections have had evidence of being linked with specific types of cancer which can change or complicate the treatment process after diagnosis.

Several examples of infections and cancers being linked include these common illnesses: human papillomaviruses (HPV's) being associated with cervical cancer, Helicobacter pylori being associated with gastric cancer, and salmonella typhi being associated with gallbladder cancer. There are also infections linked to colon cancer and lung cancer but how are infections related to cancers?

The process of how cancer develops is complicated but there are certain forms of bacteria that is associated with cancer formation that differs from viruses and infections. In some cases bacterial infections may lead to cancer especially if the infection is recurring. Bacteria may cause cancer in a variety of ways including chronic infections which disrupt regular cells causing inflammation and promoting cancerous growth.

Bacteria can damage DNA and cause DNA to mutate which alters control of the gene meaning it may not die when it should during the cell mutation process. The immune system is often weakened and suppressed and it is an important aspect in helping the body fight cancer. Bacteria can affect the way the immune system recognizes and fights bacteria and sometimes causes the immune system to stop recognizing toxins it should be fighting.

For the most part many people won't get cancer after an infection but it helps to take necessary precautions if you do get an infection and to keep from getting infections in the future. Keep in mind that everyone is different and people may be more susceptible to cancer than others. Your background and genes may contribute to your risk of cancer or infection and for some this may include where you live and the population.

Chronic infections may pose a risk for cancer development but with treatment of the infection your chances are greatly reduced. Preventing infection all together is even better and this can include simple measures that can be done regularly such as adopting good hygiene habits and cooking foods thoroughly. It may help to learn who is more likely to get infections such as groups that are considered high risk and look into eliminating infection risk overall.

Also keep in mind that if you get a certain infection and you have successfully treated it doesn't mean the risk isn't there for cancer. As mentioned infections don't always lead to cancer development but if you develop an infection take the necessary steps to keep it under control and get medical attention as soon as possible. Understanding cancer risks can help you live a positive lifestyle reducing chances of infection and cancer.
