From WIKIPEDIA:

"An adenoma is a benign tumor of glandular origin...over time they may progress to become malignant, at which point they are called adeno-carcinomas. Even while benign, they have the potential to cause serious health complications by compressing other structures and by producing large amounts of hormones..."

The January 15, 2013 issue of the International Journal of cancer incriminates red and processed meat intake with pre-growth incidence of colon cancer.

"Increased intake of red and processed meat is associated with significantly increased risk of Colorectal Adenomas."
