… Largely preventable or treatable infections with viruses, bacteria and parasites cause about two million new cancer cases and 1.5 million cancer deaths each year, said a study published Wednesday.
This amounted to about one in six of the 12.7 million new cancer cases reported in 2008, said the report in The Lancet Oncology journal.
"Application of existing public health methods for infection prevention, such as vaccination, safer injection practice or antimicrobial treatments, could have a substantial effect on the future burden of cancer worldwide," said the report by the International Agency for Research on Cancer in Lyon, France.
Four infections, hepatitis B and C, human papillomavirus (HPV) and the Helicobacter pylori stomach bacteria, accounted for the bulk of the cases, some 1.9 million -- mostly gastric, liver and cervical cancers.
Infection-related cancers accounted for 3.3 percent of new cases in Australia and New Zealand, but 32.7 percent in sub-Saharan Africa, said the report, based on a study of 27 cancer types in 184 countries.
Cervical cancer accounted for half the infection-related cancers in women, and liver and gastric cancers for 80 percent of cases in men.
"Around 30 percent of infection-attributable cases occur in people younger than 50 years," said the report.
Poster Comment:
With immune system preoccupied with infection perhaps not enough resources to fight on another front. From among comments: Sharon • Hazlehurst, Georgia • H. pylori can be treated with anitbiotics. It is a bacteria that is known to be a catalyst for stomach ulcers. Silicon Cowboy @Sharon - Been there, done that - almost died of internal bleeding. After a weekend in hospital, where they put a garden hose down my throat - so they could cauterize the ulcer, I got a combo of antibiotics. It is not a catalyst, it is a cause. The intestines have a protective mucus membrane. This is a Helio, means it is like a corkscrew. Penetrates that membrane, tissue can be destroyed by contact w/ digestive juices. Damage can go so deep, blood is getting into the digestive track. Great fun.
