In most cases, stomach cancer is caused by bacteria. The reason cervical canceras well as some other types of cancers of the genital organs and oral cavity are viruses. And some chronic viral infections can lead to liver cancer.
In a new report from the American Association for Cancer Research (American Association for Cancer Research) it is saidwhich accounts for such infections about 13% of all cancer cases in the world.
However, not everything is so bad. Scientists have identified 4 common infections that can potentially cause cancer and know how to prevent the development of cancer. According to Michael Pignone, professor of medicine at the Duke School of Medicine, “we are close to turning what used to be some common cancers into rare diseases.” writes The New York Times.
Human papillomavirus (HPV)
This virus sexually transmitted. In most people who have caught HPV, the infection goes away on its own, researchers note. But approximately 10% of women develop a persistent infection in the cervix with a high risk of cancer.
Most people who are sexually active are infected with the human papillomavirus at least once in their lives. Using condoms can protect against the virus, however the best protection is vaccination.
In the Center for Public Health recommend vaccinate children with two doses at the age of 9-14 years, more before the beginning of sexual life. Boys are also vaccinated, because they can be carriers of the virus.
To patients with human immunodeficiency virus (HIV) must be entered 3 doses vaccines regardless of the manufacturer.
“The HPV vaccine is not recommended for all adults over the age of 26, as it may not be as effective at this age. However, after consulting a doctor, adults between the ages of 27 and 45 can also be vaccinated.” – they add in the CGZ.
Hepatitis B and C
According to medical oncologist from Texas (USA) Dr. Sunyoung Lee, viruses hepatitis can cause liver cancer – they cause permanent inflammation that leads to scarring and cirrhosis. In some cases, hepatitis B changes healthy liver cells.
In the Ministry of Health they tellthat hepatitis B maybe in several ways, such as:
- from infected mother to child;
- from an infected child to a healthy one during the first 5 years of life;
- during unprotected sexual contact;
- with saliva, for example, through a kiss;
- together with various body fluids: menstrual blood, vaginal secretions or semen;
- through reuse of syringes and needles.
In return hepatitis C virus is transferred through blood Doctors can detect both infections with blood tests.
One of the effective ways prevention of hepatitis B there is vaccination. Vaccination prevents infection, as well as the development of chronic consequences in 96% of cases. Baby should receive 3 doses of vaccine.
Vaccines against hepatitis C now does not exist but the best way to prevent the risk of infection is do not use shared needles.
Helicobacter pylori (H. pylori)
This bacterial infection is very common – about half of the world’s population are its carriers. But only 1-3% of them develop cancer. Scientists have not yet found out why and how this happens.
Bacteria are found in saliva, dental plaque and feces. According to Dr. Nina Salama, senior vice president for education at the Fred Hutch Cancer Center (USA), infection usually occurs in childhood through close family contact or crowded living quarters, and most cases are asymptomatic.
The infection causes chronic inflammation of the stomach lining, which promotes cancer, Salama says. In addition, bacteria “bring” toxic proteins into cells that can cause mutations. The strain of bacteria and a person’s genetics may also play a role.
Best a way to prevent the spread of H. pylori in the family is to avoid sharing dishes, glasses and toothbrushes whenever possible. Washing your hands thoroughly with soap for at least 20 seconds before preparing food and after using the toilet will kill it.
