A review of studies found women who ate high levels of processed meat had a 9% increased risk of the cancer compared with those who ate little of it.
What is the risk?
In the UK about 14 out of every 100 women will get breast cancer at some point in their lives. That means a 9% increase in risk in this population would be expected to translate into roughly one extra case of cancer in every 100 women.
The WHO lists processed meat as carcinogenic, primarily because of evidence linking it to a raised risk of bowel cancer, while it says red meat is "probably carcinogenic".
