Does Caffeine increase Breast Cancer Risks?

Breast cancer is a condition affecting, statistically, one of each eight women in the USA. It takes much time, commitment and money to treat it, while healing is generally possible only once the problem has been revealed at an early stage. Unfortunately, medical scientists failed to come up with a comprehensive list of causes by now. Still, a number of major risk factors are well known; they include:

  • an individual’s heredity and the history of getting the condition in the family;
  • an older age;
  • obesity;
  • alcohol addiction;
  • exposure to radiation, etc.

While some people believe coffee should be added to the list too, experts are more optimistic and do not support this attitude.

What Studies Say

As far back as in 1985, a study on the subject was conducted. Involving more than 3,000 women, it revealed no correlation between how much coffee a woman drank and her individual breast cancer risk index. More recently, a similar free research was conducted in Sweden in 2011. It focused on postmenopausal women and showed a decrease in the discussed measure as a result of drinking coffee. While the participators involved had to drink coffee in rather big amounts, the variation of the output parameter was only slight.

In 2013, an extensive research was conducted. It actually involved processing available data derived from several earlier studies on the subject. All in all, over 59,000 breast cancer events were investigated. This huge job resulted in findings supporting absence of any statistically significant correlation between drinking coffee and the danger for a woman to get breast cancer. The only practicable result was probably confirmation of the hypothesis that drinking coffee does reduce risks (even though to a slight extent) when it comes to female participators in a postmenopausal period. The findings are probably credible as they were confirmed once again during another study conducted in 2015. More frequent coffee drinking was correlated with lowering breast cancer risks. Giving preference to highly caffeinated sorts of the drink produced the same effect.


The Bottom Line


The findings described are quite practicable given the current background. The fact is that almost a half of adults in the United States, statistically, fall into a category of permanent coffee drinkers, which means they consume the product at least once a day. The average daily consumption amounts to three cups.

One promising conclusion we can take from the abovementioned topical studies is that the drink at least does not increase perils in terms of breast cancer. Quite the opposite, lower risks were associated with heavier coffee drinkers, specifically with women in a postmenopausal period. This is quite encouraging news.
