New study links processed meats to breast cancer | Simplemost

Eating processed meats like bacon, sausages and ham could increase the risk of breast cancer, a study said.

Regular consumption of these foods was associated with a 9% higher risk of breast cancer, according to an analysis of previous studies involving more than 1.2 million women.

The findings follow earlier research by the World Health Organization, which classified processed meat as a carcinogen, after discovering that its consumption could cause various types of cancer.

Processed meats are those that have been preserved by smoking, drying or salting.

"This systematic review and meta-analysis show significant positive associations between processed meat consumption and breast cancer risk," the authors wrote.

"Cutting the processed meat seems beneficial for the prevention of breast cancer," added Dr. Maryam Farvid, senior author of Harvard T.H. Chan School of Public Health.

But scientists have not suggested people to completely cut processed meats from their diet, and experts have warned that the study should be viewed with caution.

"The individual risk is small"

The paper leaves "many unanswered questions" and does not prove that increased consumption of processed meat has directly led to breast cancer among the women studied, according to Kevin McConway, professor emeritus of applied statistics at the University of Toronto. Open University of the United Kingdom.

"I just can not tell you how many cases of breast cancer there would be more if everyone ate an extra bacon sandwich every day – this research just can not give that information," added McConway.

The authors of the study admitted that previous studies on the link between processed meat and breast cancer had produced "inconsistent" results.

According to the World Cancer Research Fund, breast cancer is the most common form of cancer among women worldwide, while Cancer Research UK estimates that about a quarter of cases are preventable.

Gunter Kuhnle, an associate professor of nutrition and health at the University of Reading, said that "if the evidence to classify processed meat as a carcinogen is solid, the real risk to the individual is very low and more relevant to the population. "

"Whether [study] justifies a change of current [UK] The recommendation of 70 grams of red and processed meat is questionable, "he added.
