MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Prior prospective studies on red and processed meat consumption with risk of breast cancer have produced inconsistent results.
Current meta-analysis of 15 prospective studies shows that women who eat a high amount of processed meat each day may have a higher risk of breast cancer than those who don’t eat or have a low intake in their diet.
MedicalResearch.com: What should readers take away from your report?
Response: There are few potentially modifiable risk factors for breast cancer and cutting out processed meat such as bacon, sausage, or hot dog from the diet may be a feasible way to help lower the risk.
MedicalResearch.com: What recommendations do you have for future research as a result of this work?
Response: One of the limitations of this study is that we compared the highest level of intake versus the lowest, therefore, it is not possible to say exactly how much processed meat is safe to eat.
Further studies examining dose-response associations between processed meat consumption and breast cancer risk are needed.
