Coffee may reduce risk of breast cancer


Posted on | May 17, 2011 | No Comments

Drinking coffee may do more than help perk you up in the morning (or whenever you happen to like it). A recent study shows drinking five cups or more a day reduces the risk of breast cancer.

The study published by a researcher at the Karolinska Institute in Sweden, showed that women who drink five or more cups of coffee a day are 57 percent less likely to develop estrogen receptor-negative breast cancer than women who drink less than a cup of coffee a day.

There are many different types of breast cancer, and estrogen receptor-negative breast cancer is one type whose growth is not affected by estrogen. Other kinds of cancers, such as HER2-postive may not be inhibited by caffeine in the same way.

Health benefits or not?

In the past, studies have pointed to coffee offering protective effects against endometrial and colorectal cancers, but not against breast, pancreatic, ovarian, kidney or prostate cancers. This new study seems to indicate that certain types of breast cancer may be affected by drinking coffee after all.

While the information about coffee and cancer may seem conflicting, the evidence seems to suggest that it may offer some protective benefits for those who like to drink coffee.

“I wouldn’t necessarily tell my patients after reading an article like this to drink more than five cups of coffee a day to lower your risk of a particular type of breast cancer,” said Dr.  Michelle Shayne, an oncologist and assistant professor of medicine at University of Rochester Medical Center in New York, said in My Health News Daily. “It’s just that if you happen to enjoy coffee consumption, you may possibly have an added benefit of protection against one subtype of breast cancer.”

 What do you think?

So, would you drink five cups a day to reduce your risk of breast cancer?
