The four infections, including human papillomavirus, Helicobacter pylori and hepatitis B and C, are responsible for about 1.9 million cases of gut, cervical and liver cancers
It has been discovered that four specific infections can be largely responsible for one in six cancers around the globe.
Dr. Catherine de Martel and Dr. Martyn Plummer, both from the International Agency for Research on Cancer in France, have found that four infections can be tied to certain cancers in men and women.
The four infections, including human papillomavirus (HPV), Helicobacter pylori and hepatitis B and C, are responsible for about 1.9 million cases of gut, cervical and liver cancers.
According to the study, the relationship between these infections and cancers are three times more likely in the developing world like east Asia (22.9 percent) versus the developed world like the United Kingdom (7.4 percent).
The study also found individual results for women and men. For instance, 50 percent of cancers related to infection in women were of the cervix while 80 percent of cancers related to infection in men were liver and gastric cancers.
"Infections with certain viruses, bacteria and parasites are some of the biggest and preventable causes of cancer worldwide," said de Martel and Plummer. "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."
The study discovered that about a third of the infection-related cases affected people under the age of 50 years old.
This study examined incidence rates for 27 different types of cancers in 184 countries around the world. HPV was linked to cancer of the cervix, hepatitis B was linked to liver cancer, and H. pylori was linked to stomach cancer.
