  • The bacteria known as Fusobacterium nucleatum live in the human mouth and are rarely found elsewhere.
  • But in cases of cancer of the colon or the rectum, the bacteria are found in tumours in the gut.
  • There, they help cancer cells escape from the immune system and spread to other parts of the body.
  • Researchers has identified a distinct subtype of the bacterium that’s found in relatively greater quantities in colorectal cancer (CRC) tumours.
  • CRC is the seventh most common type of cancer in India, where the number of cases rose by 20% from 2004 to 2014.
