BOSTON, NETRALNEWS.COM - Drinking one to four or more cups of coffee a day can help people with advanced colorectal cancer live longer and slow the progression of their disease.
The study, conducted by the Dana-Farber Cancer Institute in Boston, United States (US), was based on about five years of data from 1,171 people treated with chemotherapy for stage four colorectal cancer.
Overall, as coffee consumption increases, so do the benefits, and whether the coffee is caffeinated or decaffeinated makes little difference, according to research published in the journal JAMA Oncology.
During the study period, about five percent were less likely to get worse in people who drank one cup of coffee a day, compared to those who didn't drink coffee, 18 percent less likely for two to three cups daily and 22 percent less for four or four cups of coffee a day. .
Meanwhile, to survive, those who drank four or more cups per day increased their survival rate by 36 percent compared to those who did not drink.
One cup a day resulted in a seven percent increase, and two to three cups increased the survival rate by 18 percent.
"Study participants who drank the most coffee lasted for about 39 months compared to 31 months for those who didn't drink," said a researcher from Dana-Farber.
Although research has not yet determined why coffee might slow the progression of deadly colorectal cancer, cancer experts theorize that it may be related to the antioxidant, anti-inflammatory and insulin-sensitive effects of compounds found in coffee.
Research shows that coffee can lower the risk of several other types of cancer. The US Dietary Guidelines consider moderate coffee consumption - described as three to five cups a day - to be safe and healthy for most people. But problems can develop for people who are sensitive to caffeine, such as headaches, insomnia, dizziness, and others, as reported by WP.
