Gut bacteria may be one culprit for increase of colorectal cancer in younger people
(PHYSorg.com Medicine & Health)

A bacteria typically linked to periodontal disease, Fusobacterium nucleatum (F. nuc), could play an important role in the rising incidence of colorectal cancer in people under the age of 45. Another type of bacteria, Moraxella osloensis, has been found in colorectal cancer tumors at a nearly four-fold higher rate in people over 75 than in those under 45 years of age, pointing out how differences in the bacteria that comprise what is known as the body`s microbiome could affect cancer outcomes to varying degrees.
