A new study has found that regular coffee consumption prevents the return of colon cancer after treatment and improves the chances of a cure.
This association between coffee and colon cancer has been revealed by a study conducted by Dana-Farber Cancer Institute .
The study included all 1000 patients, all of them treated with surgery and chemotherapy for stage III colon cancer. It was found that greatest benefit was found when patients consumed four or more cups of coffee in a [460 milligrams of caffeine]. Two to three cups provided modest benefit while one cup or less provided little protection.
As compared to patients whod were not coffee drinkers, the patients who drank coffee were 42 percent less likely to have their cancer return and were 33 percent less likely to die from cancer.
The study has been published in the Journal of Clinical Oncology.
In patients with stage III colon cancer, the cancer has spread to the lymph nodes near the original tumor but there are no signs of further metastasis.
These patients are said to have a 35 percent chance of recurrence.
The researchers have advised the coffee drinkers who are being treated for colon cancer not to stop drinking coffee.
But researchers, in spite of the encouraging results, wanted more studies for making a recommendation to those who did not drink coffee.
This study is first of its kind to study an association between caffeinated coffee and risk of colon cancer recurrence and adds to number of recent studies suggesting potective effects of coffee.
In various previous studies, coffee had been found to reduce risk of postmenopausal breast cancer, melanoma, liver cancer, advanced prostate cancer.
Coffee drinking has also been linked to type 2 diabetes. The colone cancer and diabetes share same risk factorss — obesity, a sedentary life style, a diet high in calories and sugar, and high levels of insulin.
Coffee and Colon Cancer – How Does Coffee Protect Against Colon Cancer
The researchers said that the lowered risk of cancer recurrence and deaths was entirely due to caffeine and not other components of coffee. The cause of the association between coffee and colon cancer was not clear. One of the forwarded hypothesis is that coffee consumption increases body’s sensitivity to insulin thus reducing the need for insulin production and in effect reduction of inflammation which is a risk factor for diabetes and cancer.
What Other Measures Can be taken to Reduce Cancer Risk
- Avoid obesity
- Regular exercise
- A healthier diet
