Scientists continue to rethink the idea that moderate drinking offers health benefits. Adults younger than 50 have been developing breast cancer and colorectal cancer at increasingly higher rates over the past few decades, and alcohol use may be one factor driving the trend, according to a scientific report published recently. The report, by the American Association for Cancer Research, highlights scientific breakthroughs that have led to new anticancer drugs and improved overall survival.
But the authors also described a troubling pattern. Even as cancer death rates have declined , the overall incidence of several cancers has been rising inexplicably, with an especially alarming increase among younger adults in cancers of the gastrointestinal system, like colorectal cancer. The report estimates that 40% of all cancer cases are associated with modifiable risk factors.
It recommends reducing alcohol consumption, along with making lifestyle changes such as avoiding tobacco, maintaining a healthy diet and weight, exercising, avoiding ultraviolet radiation and minimising exposure to pollutants..
