The study involved 884 patients from the University of Texas MD Anderson Cancer Center with bladder tumors and 878 people without disease. The compilation took into account age, gender and ethnicity. To collect data, the scientists used the standard international questionnaire, which determines eating habits. The study participants were then divided into four groups depending on the amount of their meat consumption. Over the course of three years, methods of meat preparation and the emergence of the three most frequently detected HAAs were also examined.
In the group with the highest consumption of red meat, the risk of bladder cancer was 50 percent higher than that of the weak meat eater. Especially the diet with steaks, chops and fried bacon proved to be critical, but also sharply heated white meat of chicken and fish increased the number of tumor patients. In addition, the degree of Durchbratens proved to be a criterion: The study participants who preferred half-meat meat, reduced the likelihood of illness by half? a "medium" prepared steak is therefore preferable to the "well-done". The scientists were able to prove that the disease also broke out more often in certain genetically determined metabolic forms.
"Our research confirms the relationship between diet and cancer, " explains study author Xifeng Wu. "The findings confirm our suspicion that people who eat spicy, fried or grilled red meat are more likely to develop bladder cancer." Scientists now want to develop a predictive model for an individual cancer risk that includes factors such as the environment, diet and genetic makeup. displayJie Lin (University of Texas MD Anderson Cancer Center, Houston) et al .: Lecture 101st Annual Meeting of the American Association for Cancer Research ddp / science.de?
