Tests in mice show a possible mechanism for how it happens. The findings, published in the journal Cancer Research, support studies that suggest people who consume more sugar have a higher risk of cancer — especially breast cancer.“A lot of patients are told it doesn’t matter what you eat after you are diagnosed with cancer. This preliminary animal research suggests that it does matter,” said Lorenzo Cohen of the University of Texas M.D. Anderson Cancer Center, who worked on the study.
The findings add one more piece of evidence to a growing body of science that shows a Western-style diet is a major risk factor for many types of cancer. Other research has shown that at least two-thirds of all cases of cancer come down to lifestyle choices — tobacco use, an unhealthy diet and a lack of exercise.
