New research in the International Journal Of Cancer looks at 15 previous studies and finds eating processed meats is associated with a nearly 10 percent higher breast cancer risk.

“When we look at all the evidence together there is an increased risk of breast cancer with diets high in processed meats,” Dr. Mariana Stern at USC’s Keck School of Medicine said.

Processed meats like bacon, ham, sausage and deli meats including turkey are altered to improve flavor and preservation.

In 2015, the World Health Organization classified processed meat as a carcinogen because studies show it can increase risk for colorectal and potentially stomach cancers.

Dr. Stern says avoiding processed meats is key and red meat should be limited to about 18 ounces per week.

The American Cancer Society recommends physical activity at least 30 minutes per day for breast cancer prevention.
