Burgers may increase a woman’s risk of breast cancer, new Harvard research suggests.
Processed meat has long been linked to other cancers of the pancreas, prostate and bowels, but this study is the first to show a link with tumors that start in the breast.
Women who consumed the most processed meat were nine percent more likely to develop the disease, according to a meta-analysis of data from 28 previous studies.
They found no elevated risk for those who ate unprocessed red meat such as beef, lamb, pork, veal, goat and mutton.
Lead author Dr Maryam Farvid, of the Harvard T.H. Chan School of Public Health, said: ‘Previous works linked increased risk of some types of cancer to higher processed meat intake.
‘This recent meta-analysis suggests that processed meat consumption may also increase breast cancer risk.
‘Therefore, cutting down processed meat seems beneficial for the prevention of breast cancer.’
