Heavy consumption of processed meats linked to increased risk for pancreatic cancer
...esearchers from the Cancer Research Center and USC examined the relationship of diet to pancreatic cancer among 190,545 men and women of African-American, Japanese-American, Caucasian, Latino and Native Hawaiian origin who were part of the Multiethnic Cohort Study in Hawaii and Los Angeles.
