Approximately one in eight cancer cases worldwide can be attributed to infections, according to recent research. The study identifies several infectious agents, including viruses, bacteria, and parasites, as significant contributors to the global cancer burden.
Among the pathogens linked to cancer, Helicobacter pylori, a type of stomach bacteria, is associated with around 760,000 cancer cases annually. This bacterium is known to increase the risk of stomach cancer. Another major infectious cause is the human papillomavirus (HPV), which is responsible for nearly all cases of cervical cancer.
Experts emphasize that an infection with these agents does not necessarily result in cancer, but their presence increases risk. Importantly, many of these infection-related cancers are considered preventable with currently available medical interventions.
In the United Kingdom, the National Health Service (NHS) offers the HPV vaccine to boys and girls aged 12 to 13 as part of a broader strategy to reduce the incidence of cervical cancer. The NHS has set an ambitious goal to eliminate cervical cancer in England by the year 2040. Achieving this objective, however, requires high participation rates in screening programs.
Current data indicate that only about 70% of eligible women in England are up to date with their cervical smear tests. Public health officials urge those who have not responded to screening invitations to make appointments promptly. Additionally, individuals experiencing persistent indigestion are advised to consult their general practitioners about testing for Helicobacter pylori, which can facilitate early detection and treatment, potentially lowering the risk of cancer development.
These findings highlight the critical role of infection prevention and early detection in reducing the global cancer burden. Efforts to increase vaccination coverage and screening uptake remain essential components of cancer control strategies.
