Many people don’t know that some cancers are closely related to bacterial and viral infections. After being infected with the virus, not only causes the patient to suffer, but will also lurk in the body for a long time, causing mutations in the cell genes and increasing the risk of cancer. " Nature-Genetics " research shows that 20% to 40% of human cancers are caused by bacteria and viruses, which is due to long-term infection, which leads to an increased chance of cancer. In particular, the following four viruses can promote the development of cancer.
Which viruses may induce cancer?
, Hepatitis B virus
According to the data, hepatitis B is one of the causes of liver cancer . It only takes 3 steps to develop from chronic hepatitis B to liver cancer, and it develops from hepatitis B to cirrhosis , and then to the liver cancer stage. Chronic hepatitis B is a liver disease caused by hepatitis B virus infection. The hepatitis B virus is particularly stable and difficult to be inactivated. Whether it is high temperature, low temperature, or alcohol and ultraviolet rays, it cannot kill the hepatitis B virus. The main transmission routes of hepatitis B virus include blood, behavior with partners, and maternal and infant.
Early vaccination of hepatitis B vaccine is an effective method to prevent hepatitis B, especially those with immunity deficiency, newborns and family members of hepatitis B patients. Regularly go to the hospital for 5 hepatitis B and liver function tests to help you find out if you are infected with hepatitis B virus.
, HPV virus
High-risk persistent HPV infection is the main factor in inducing cervical cancer . HPV virus is mainly transmitted through behavioral behavior with partners. In addition to inducing cervical cancer, it may also cause oral cancer, anal cancer, vulva cancer and . So far, more than 200 HPV subtypes have been discovered, most of which are low-risk HPVs, which are easily eliminated by the powerful immune system.
Thankfully, there is HPV vaccine on the market now. The nine-valent vaccine is suitable for women aged 16 to 26, the quadrivalent vaccine is suitable for women aged 20 to 45, and the bivalent vaccine is suitable for women aged 9 to 45. Even after vaccination, you should not be too careless. You also need to undergo TCT and HPV screening for regularly. At the same time, you should be clean and not have multiple partners; pay attention to hygiene during menstruation and puerperal periods; if contact bleeding or irregular bleeding occurs, you should seek medical treatment immediately.
3, Helicobacter pylori
Helicobacter pylori grows in the gastric mucosa, continuously stimulating the gastric mucosa, inducing gastric ulcer and chronic gastritis, increasing the risk of gastric cancer . The symptoms are not very significant after infection with Helicobacter pylori. Most patients have developed chronic gastritis or gastric ulcers when visiting the hospital, mainly manifested as upper abdominal discomfort, abdominal pain, belching, , acid reflux and indigestion.
You should pay attention to dietary hygiene, make separate meals, use public spoons and chopsticks to reduce the number of times you eat outside; cook the food you eat thoroughly and stay away from spicy, irritating and raw and cold foods; after infection with Helicobacter pylori, you should completely cure it through quadruple therapy.
4, EB virus
Studies have shown that EB virus infected people have a high risk of nasopharyngeal carcinoma , and most patients with nasopharyngeal carcinoma contain antibodies to this type of virus in the serum; EB virus can also increase the risk of gastric adenocarcinoma and lymphoma . After infection with EB virus, it mainly manifests as headache, fever, cough, small papules with light redness on the face, and rash on the mouth. This type of virus often spreads in the form of saliva, so you should pay attention to oral hygiene and separate meals when eating.
Message from the doctors
does not necessarily cause cancer after being infected with the virus. Take HPV virus as an example. Many low-risk HPV viruses can be eliminated by the immune system, so they cannot be overtreated. The most important thing is to do a good job of life conditioning, correct bad behavioral habits in a timely manner, actively control the activity of the virus, and go to the hospital for relevant examinations regularly to facilitate early detection of abnormalities and early treatment.
