Colon cancer patients who regularly drink caffeinated coffee may be lowering their risk of tumor recurrence and death from the disease, suggests a study published in November 2015 in the Journal of Clinical Oncology.
The observational study found that people with advanced (stage 3) colon cancer who drank four or more cups of caffeinated coffee a day had much lower odds of having a recurrence of the disease, or dying from it, by 52 percent compared with non-coffee drinkers.
Even people who regularly drank just two or three cups a day seemed to reap some of the same benefits, although to a lesser degree.
Another observational study, published in Cancer Epidemiology, Biomarkers & Prevention in April 2016, compared the coffee-drinking habits of more than 9,000 adults and found that “… drinking coffee is associated with lower risk of colorectal cancer, and the more coffee consumed, the lower the risk,” according to Stephen Gruber, MD, PhD, director of the University of Southern California Norris Comprehensive Cancer Center in Los Angeles and senior author of the study.
