|About a third of 50- to 70-years-olds carry the bacterium Helicobacter pylori|
A mass screening campaign for Helicobacter pylori is advocated by Jack Cuzick of London University. Helicobacter pylori can cause stomach bleeds so elimination with antibiotics means that risk of ulcers with aspirin is reduced. After elimination of Helicobacter pylori, everyone between 50-70 years would be recommended to take a daily aspirin to reduce risk of all cancers by 25%.
