Bacteria drive tumor formation in hereditary colon cancer

Scientist show in a new study that two species of bacteria work together to stimulate tumor formation in patients with an inherited form of colon cancer. These patients harbor the bacterial species inside their colon. Interestingly, the same species were also discovered in people who develop a sporadic form of colon cancer. The mechanisms behind the phenomenon are explained in another study performed in mice, in which researchers showed that the bacteria promote an immune response that stimulates the formation of tumors. The findings could lead to new ways to more effectively screen for and ultimately prevent colon cancer.
