On December 6, the internationally renowned British Journal of Cancer published online the results of a study by British researchers, “The fraction of cancer attributable to lifestyle and environmental factors in the UK in 2010. The fraction of cancer attributable to lifestyle and environmental factors in the UK in 2010.” The study shows that more than 40% of cancer patients suffer from cancer due to poor lifestyle habits, including smoking, drinking and poor diet. Nearly half of the 130,000 cancers diagnosed in the UK each year are due to poor lifestyle habits, with cigarettes being the biggest killer, with 23% of men and 15.6% of women developing cancer due to cigarettes. Cigarettes are the biggest killer, with 23% of men and 15.6% of women suffering from cancer due to cigarettes. Prof. Barkin, who was responsible for the study, pointed out that many people believe that cancer is due to bad luck or a cancer gene in their bodies, but from the findings of the study, more than 40% of the cancer cases are in fact avoidable. Prof. Barkin suggested that the most important thing for men to do to prevent cancer is to quit smoking, consume more fruits and vegetables, and reduce the consumption of alcoholic beverages. The most important thing for women to do to prevent cancer is to quit smoking, but at the same time, they should pay attention to their weight. Studies show that 1 in 10 breast cancer patients are overweight. The report also shows that half of the esophageal cancer patients are due to too little fruits and vegetables, and another 1/5 patients are due to alcohol consumption. Cancers of the oral cavity and larynx are almost always caused by poor lifestyle habits.
