Scientists from the Perm National Research Polytechnic University (Russia) have identified the most common sources of carcinogens in everyday life, the press service of this scientific institution informed Gazete.Ru.

Carcinogens are substances that can cause or contribute to cancer. They are chemical (some substances contained in cigarette smoke, asbestos, benzene), physical (ionizing radiation and some other phenomena), or biological (certain viruses, including the human papillomavirus).

Today, more than 500 carcinogenic compounds are known to science, and people face some of them every day.

According to the Perm National Research Polytechnic University scientists, nitrates and nitrites have been recognized as carcinogenic substances found everywhere. They are included in nitrogen fertilizers, as well as in the content of many foods—including meat.

Nitrates and nitrites—in high concentrations—cause cancer and have a toxic effect on the body. To protect health, researchers recommend eating less processed meat and including fresh vegetables and fruits in your diet to get antioxidants. The latter prevent acid stress, one of the possible causes of cancer.

In addition, city dwellers constantly interact with polycyclic aromatic hydrocarbons and their derivatives, which are formed as a result of burning of fuel and household waste and smoking.

Some residues of burning organic materials are extremely toxic and carcinogenic. In addition, most of them are "flying," which poses a special risk for all those around them, noted the Perm National Research Polytechnic University. Experts advise the residents of those regions to have air-conditioning systems at home.

In addition, known carcinogens are ultraviolet rays from the sun and such pathogens as the bacterial pathogen of gastritis Helicobacter pylori and the hepatitis B virus. You can protect yourself from them with the help of SPF cream, maintaining hygiene, and vaccination.
