Processed Meats Have Been Linked To Breast Cancer — We’re Freaking Out

According to new scientific research, the consumption of processed meats has been linked to an increased risk for developing breast cancer. As the New York Times reports, processed meats like ham, bacon, hot dogs, and salami have long been considered carcinogens, and therefore proponents of increased cancer risk. This evidence has been largely based on studies of colorectal, pancreatic, and prostate cancers. A new study now shows that processed meats may have the same effect on breast cancer risk — but we shouldn’t freak out *just* yet.

The study, published in the International Journal of Cancer, combined findings from 16 previous observational studies that looked at the link between processed meats and breast cancer.

Researchers found that those who consumed a high amount of processed meats (about 25 to 30 grams per day), had a 9% increased risk for breast cancer in comparison to those who consumed a low amount of processed foods (about 0 to 2 grams per day).

But none of this new research is backed by solid evidence. Yes, scientists agree that processed meats seem to be the common denominator in many cases, but the fact that these findings are based on observation alone leaves a lot of gray area.

For example, as reported by the BBC, many cases within the 16 studies gave different definitions of what the highest amount of processed meats consumed to increase cancer risk is, meaning current calculations may be skewed. And these numbers were collected by simply asking participants how much they eat rather than observing them actually eating processed foods.

As the Times stated, the authors of the study realize that observational studies cannot prove one thing or another. But even so, lead author and researcher in the department of nutrition at Harvard, Maryam S. Farvid, recommended that women cut down on processed meats.

Dr. Gunter Kuhnle, associate professor in nutrition and health at the University of Reading, told the BBC that he’s unsure if women and men should cut down their processed meats consumption based on this study alone. He said that the realistic risk of processed meats contributing to breast cancer is “very small.”

Regardless, the findings of this new study are interesting and certainly something women should take into consideration. As always, discuss your diet and family history with your doctor to make sure you’re giving yourself the best care.
