People of some professions suffer more often from cancer
A group of researchers from the University of Ottawa представилf scientific work, where you state that firefighters are the most susceptible to cancer.
It’s all in the carcinogens that occur when burning plastics and building materials. Also harmful dioxin, which is formed generally in any burning. According to Jennifer Keir, team leader, it is proved that when a man puts out the fire, the body is able to accumulate a large number of the same carcinogens that penetrate the skin. Gradually they can be washed out of the cells, however, DNA has already been damaged and it is not going away ever. There is a need to develop methods that help to carry out a complete purification of the body and protecting it from substances such a plan.
Jennifer Keir said that scientists had long suspected: to extinguish the fire very dangerous not only because of direct threats of death such specialists through smoke, heat and fire when they save people, but also because of the likelihood of cancer development. In 2007, experts of the International Agency for research on cancer have put forward the theory that the fire may get this disease. Later it was partially confirmed by medical services of the United States, which watched the health of those who were engaged in the fighting, however, the direct causal link established, in fact, was not. Keir and her team managed to fill these gaps in the availability of a large number of canadian firefighters-volunteers who have agreed to participate in the experiments and pass a number of tests showing their state before the call for the next mission and return with him.
After collection and monitoring of hundreds of samples, the experts have paid great attention to their chemical composition, trying to understand if I can get the carcinogens in the smoke of the fire in the body of those who are fighting with fire, and if so, how it happens. However, experts at the same time collecting data for comparison, and among those who work in the office, not having the habit of Smoking. It turned out that the carcinogens in the urine and on the surface of the skin the fire was concentrated more than twice after they were called, which, respectively, the cells stronger and more mutated over the following days. It is curious that this substance was in the body of fighters with the fire not in the air and through absorption into the skin and mucous membranes. Such conclusions were made due to the fact that the urine of canadian firefighters did not contain proteins CC16 and PGF2A, which could indicate that damaged the lungs. Why is this happening? Scientists expressed the assumption that, first and foremost, the respiratory system is protected is usually a good idea, but the means to cover the whole body rarely used. In addition, in connection with high temperatures is the opening of pores on the skin, and they are more permeable to molecules of carcinogens and also have a greater tendency to absorption of different volatile molecules from the air. Both the first and the second, according to the experts, may explain why harmful chemicals are in the body of the fire in such large numbers.
What other profession can lead to cancer? According to the study of Australian scientists, often of a malignant tumor can occur in those who work a lot in the sun, too nervous and spends little sleep. Accordingly, in their opinion, most of the “risk zone” has touched farmers, builders, drivers and sellers on the markets.
According to researchers from the University of California, no less dangerous to operate and the pilot of the aircraft – due to ultraviolet radiation. The fact that the windshield it absolutely does not protect, but rather only enhances. Accordingly, if you sit in the cockpit an hour, it will be as if you spend twenty minutes in the tanning bed. Lead in extreme cases this may to melanoma. There is a danger of flight attendants – due to the fact that the effect of cosmic radiation, more on top. Five years ago the National Institute of occupational safety of the United States were among the 11 thousand flight attendants and it appeared that they might die from cancer much more often than others.
For astronauts, respectively, the same cosmic radiation. They get more radiation in a few times, than those that do not rise to orbit. The doctor, the scope of which includes x-rays, also have the risk of getting cancer. May affect the blood, mammary and thyroid glands, the skin. It is desirable to regularly upgrade your equipment, and if not, then at least check their own health. At risk are also those who inspect the Luggage – also because of the proximity to the x-ray apparatus. In addition to them, cancer can miners and nuclear industry workers.
There are a number of other professions in relation to different circumstances which are hazardous. The most “classical” example of soldiers serving in “hot spot”. Also this list includes all that relates to law enforcement. There are a lot of professions that can just cause problems with lungs cancer and not only him. For example, it is dangerous to work on a construction site, a factory worker, an employee of the bar or night club and so on. In fact, almost every profession can be called in varying degrees, leading to some injury or illness, all in compliance with health standards and care. If you adhere to all the rules and complied with your boss, you can work anyone, in fact – will remain alive and well.
