Data from 200,000 people
Yang’s Team evaluated data from about 200,000 volunteers in long-term studies from North America and the United States to determine whether there are correlations between the Stress at work and types of cancer.
More colon cancer and cancer of the oesophagus
The scientists were able to find. In the case of two forms of cancer, there was a correlation: colorectal carcinoma and tumors in the esophagus. Striking is often revealed in people who were exposed to a lot of Stress, and also lung cancer. This was also taking into account known risks: Smoking or unhealthy life style. Obesity can trigger depression, but also promotes cancer.
Cancer-causing agents, clarified some of the
Cancer is one of the industrial countries, not only to the frequent diseases, but also to those who cause the most death. Despite intensive research, the trigger is only partially known.
What are the known causes?
We know that Smoking, alcohol, and various toxins promote cancer. Environmental influences, diet and lifestyle play just as much as genetic systems.
Gene mutations
The science knows more than 400 genes, which can lead in the case of a Mutation, to an uncontrolled growth of cells. This unkontollierte cell growth we call cancer. In the case of five or more of these mutations at the same time, can form tumors. The cause for each of these mutations is different.
Stress have already been discussed as a trigger
Stress as a possible trigger for cancer, scientists have been discussing for longer. Stress brings about hormones in a mess, and some suspect that an increased level of the stress hormone Cortisol cells change biochemically, what promotes the formation of tumors. Other medical professionals believe that stress reactions weaken the immune system and chronic disorders of the biochemical substance can trigger a change, which, in turn, could allow cancers to arise.
Methodological Problems
Research on Stress and cancer has so far had the Problem that acute Stress probably changes in the cells caused not on the tumor formation in the human body, the decades take.
Gut in America, and esophagus in Europe
In America, the increase of cancer cases elevated work stress in intestinal tumors, in Europe, in the case of carcinomas of the esophagus showed up, so Yang.
What happens?
According to Yang, the biochemical mechanism between work stress and cancer is still unclear. So there are various biological processes that lead to the Stress of cancer can. Now you have to find out what it is.
There is evidence of other forms of cancer?
Yang’s study also revealed that there are certain other types of cancer have no detectable risk by work-related stress. So, no increase in cancers of the prostate, breast cancer and tumors, showed up at the Stressed on the ovaries. (Dr. Utz Anhalt)
