A new study in the International Journal of Cancer reviewed previous research on the link between meat consumption and breast cancer risk and concluded that processed meat increases your breast cancer risk significantly. This includes bacon, ham, sausage, hot dogs, salami, and beef jerky.
Researchers found that eating processed meat was associated with a 9% higher breast cancer risk. Interestingly, they found no significant association between red (unprocessed) meat intake and risk of breast cancer. Risk was increased in both ER-negative and ER-positive cancers. Of the 15 studies, two found a greater link between a diet of processed meat and ER-negative cancers.
"Cutting down processed meat seems beneficial for the prevention of breast cancer,” said lead author Dr. Maryam Farvid, of the Harvard T.H. Chan School of Public Health.
