Study: High crime rates increase the "aggression of cancer"

Is the infection with cancer crops, and the degree of development, in a certain environment of another difference? The answer is revealed by a recent study that the crops in patients rising in areas where crime rates are rising more aggressive properties, including faster growth rate and a greater tendency to spread. According to the study, published by the Journal of Cancerch Communications, scientists have discovered a complicated relationship between environmental pressure and cancer development, after finding tension response difference between those living in neighborhoods with higher levels of social, less than violence and between cancer tissue and sound. The study indicates that the reactions of stress in individuals from areas where crime rates are rising are significantly different from those in low crime figures, and researchers believe that chronic exposure to violence creates a unique biological environment, which can improve the development of aggressive lung cancer crops. The author, Zainab Madak, a professor of science at the University of Illinois, said the study aimed to address the high rate of lung cancer in men with brown skin, compared to white men with white skin, and found that, although men with brown skin, on average smoke and later in their lives. In another study, Madak, and her team, found that men with brown skin, living in Chicago, where violent crime rates rise, much higher levels of cortisol, one of the indicators of chronic stress, compared to those living in areas with less violent crimes. There are many other studies that have linked chronic stress and bad results to cancer patients, but scientists understand how to “penetrate the skin”, to influence the diagnosis of lung cancer limited. Lung cancer and focus of analysis in the new study on glycorticide, a group of steroid hormones such as cortisol, and these hormones are linked to receptors that regulate and participate in a variety of important functions; It helps to regulate the growth of lung tissue in the fetus, newborn and play a role in metabolism, balance, infections and immune function in this substance. First, the researchers made an assessment of genetic expression patterns in lung cancer crops, and in lung tissues free of cancer in patients who lived in different areas in Chicago, some of which have higher levels, or less violent crimes, and the team also identified the place of glycortic receptors with DNA in these tissues. The results of the two analyzes revealed that the patterns of connecting genetic resources and genetic expression in the right tissues in the cancer tissue differ, and that the patterns also differ according to where the patient lived, and in general the association with genetic resources was higher in areas where violence rise. Within the tumor tissue, those living in high crime areas had lower levels of genetic genetics in the tumor tissue. The researchers found that certain genes within the crops were activated to produce enzymes that destroy the cortisol, which is the tension hormone, and this has resulted in low levels of cortisol in the tumors compared to the natural lung tissue. The researchers say it is possible that low cortisol levels will affect the general behavior of cancer cells. Violence and cancer crimes, and in areas where violence increases, stimulates tension receptors in crops genes associated with inflammation and the rapid growth of cells, and these changes are related to worse results for lung cancer. The study indicates that the glycorticide and his receptors play a major role in the results of lung cancer worse for people living in violent, or chronic stressful environments, and although the study did not prove a direct relationship, it strongly indicates this link. The study also considered other possible consequences, such as environmental risks and poverty, but it did not find a fixed relationship between these factors and lung cancer in neighborhoods where the crime rates in the study rise. Prior to this study, scientists suspected that stress hormones could affect cancer and other healthy differences, but they did not understand exactly how it happened. The research shows that it is not only related to high stress in these diseases; If voltage responses are disrupted, it directly affects how cells work and contribute to the development of lung cancer. The results indicate that reducing violent crimes may be part of larger strategies to prevent cancer.
