Chronic inflammation is a well-known risk factor for developing colitis-associated colorectal cancer. A new study reports that aberrant activation of innate immune responses increases susceptibility to colitis and colorectal cancer. These findings identify an epithelial cell-intrinsic mechanism by which the innate immune system promotes tumorigenesis through the activation of PI3K–mTOR signalling.
