Many Studies Show Coffee To Lower Risks For Cancer

For years, the World Health Organization described coffee as “possibly carcinogenic,” and it had even linked it to increased risks of bladder cancer. However, an announcement made in 2016 reversed all of that with an announcement that found it had quite the opposite effects.

The New York Times reports that drinking coffee has been shown to lower rates of heart disease, type 2 diabetes, neurological disorders and several types of cancers. Now there is strong evidence that three to five cups of coffee a day could reduce several systemic diseases, including multiple types of cancer.

Why is Coffee Suddenly Good?

For years, studies have shown a link between the consumption of coffee and increased risks for cancers and increased mortality rates. Sudden changes in these results can raise questions. When looking into the change in research Web M.D. discusses that early studies failed to take into consideration other high-risk activities.

Coffee drinkers who smoked three packs of cigarettes a day were evaluated similarly to coffee drinkers who were nonsmokers. The same was true of other risk factors like physical inactivity. Heavy coffee drinkers tended to have higher than average risks from other sources for cancers. This oversight is possibly one of the reasons that coffee had such a bad reputation.

How Does Coffee Fight Cancer?

So what is it about coffee that helps fight off cancer? There are several ways that the consumption of coffee has been linked to the reduction of risk for various cancers.

Depending on the type of gene a woman has, drinking at least two to three cups of coffee daily can reduce risks for developing breast cancer or possibly delay its onset (Lund University and Malmö University in Sweden)

Oral cancer is reduced by 39% when 4 or more cups of coffee are consumed a day (American Association For Cancer Research)
Researchers at the University of Southern California Norris Comprehensive Cancer Center of Keck Medicine examined more than 5,100 men and women who were suffering from colorectal cancer and also 4,000 women and men who have never suffered from the diseases (control group). Researchers reported the finding that coffee was associated with a lower risk of colorectal cancer, and the more coffee the subjects drank, the lower their risk became.

Both men and women see a 40% reduction in certain forms of brain cancer (Holick, et al, published on The American Association For Cancer Research)

Colon cancer patients saw a decrease in recurrence of 42% with 4 or more cups of coffee a day.

3 cups of coffee a day can delay the onset of breast cancers (WebMD)

41% reduction in liver cancer risk if you drink 1-3 cups of coffee a day (Bravi et al, Meta-Analysis study conducted at the Istituto di Ricerche Farmacologiche Mario Negri in Milan, Italy)

Coffee drinkers are less likely to develop melanoma, a deadly form of skin cancer. (Loftfield, et al, published in The Journal of the National Cancer Institute)

60% reduction in prostate cancer risk by men who consume 6 cups of coffee a day (Science Daily)

Women who consume 3 cups of coffee have lowered uterine cancer rates

All this new research has come out in the last 20 years to show how the longevity of coffee drinkers varies, and their long-term risks are lowered.
