Researchers from the Harvard School of Public Health explains, men who consumed coffee as much as six cups or more per day will face 60% lower risk of esophageal cancer and 20% lower in the face of the formation of the type of prostate cancer compared with people who do not drink coffee.
Even just one to three glasses per day was associated with the risk 30% lower in the development of deadly prostate cancer.
"Not many studies have examined specifically the relationship of coffee consumption with the risk of deadly prostate cancer, the most important form of the disease prevented," said Wilson, a researcher in epidemiology at the Harvard School of Public Health, Boston, as quoted from News.yahoo.
Impact is the same whether the coffee was caffeinated or not, so the researchers suspect that lower risk can be associated with antioxidant and anti-inflammatory benefits of coffee.
Prostate cancer is the most common form of cancer found in men in the U.S., but not always lethal.
Blood tests can detect cancer at an early stage, and the cancer can be categorized in what is known as the Gleason score the higher the score, the more likely the cancer spread.
There are 16 million survivors of prostate cancer worldwide, and one of six men in the United States will develop prostate cancer during their lives. Risk factors specifically associated with the Western diet, rich in fats, heredity, alcohol and exposure to chemicals.
For the study, Wilson's team collected 7911 American men who reported every four years how much coffee they drank from 1986 to 2008. During the study, a total of 5035 prostate cancer cases were reported, including 642 cases of death, or metastatic.
Lower risk seen in coffee drinkers remained there even after the researchers considered other factors that specifically encourages risk and more often seen in coffee drinkers compared to people who do not drink coffee, such as smoking and no exercise.
"This adds to evidence coffee does not seem dangerous," said Wilson.
"It has been proven, consistent enough, to be associated with lower risk of Parkinson's disease, type 2 diabetes and liver cancer. This is another potential plus for a cup of coffee," he added.
