Decreased immune defense means increased infection rate, and increased infection rate is directly correlated to increased risk of cancer.
I suppose in some sense our digestive system is a type of constant infection, which could be the reason it shows up there.
A study last year suggested a link between long distance running and colon cancer, so even increasing activity may not save us.
Another study seems to hypothesise that the cancer risk may be related to reduced blood flow to the gut.
