Medical experts say that 90% of cancer patients are caused by unhealthy life habits, not DNA plays a leading role. Diet, sunlight, smoking, and disease have a “burn-up” effect on cancer, not caused by bad DNA. Dr. Smith of the British Cancer Institute said that healthy lifestyles such as non-smoking, maintaining a healthy weight, eating healthy food and quitting alcohol cannot ensure that people do not suffer from cancer, but can significantly reduce the probability of cancer.
This suggestion is not surprising. Scientists have divided how many cancer cases are due to people’s living habits, and how many cancer cases are inevitable. The controversy began 1 year ago, when studies reported that most cancer cases occurred due to DNA errors and occurred at random body ages and cell divisions. This means that most cancer patients are due to “bad luck” rather than unhealthy living habits.
At present, the latest research has reached the opposite conclusion. Dr. Yusuf Hannun of Stony Brook University pointed out that although “luck” has a certain effect, people’s unhealthy living habits can seriously affect the incidence of cancer. . These unhealthy lifestyle habits include: diet, drinking, smoking, sunlight, certain viral infections, pollution, and other factors that have not yet been determined.
The research report was published in the journal Nature, and the bad genes inherited from parents are only a cause of a few cancer cases. The results of this study confirm that most cancer cases are caused by environmental factors. If these potential factors can be identified, the incidence of cancer can be controlled.
