Can Infections Cause Cancer?

Many people may be unaware of the fact that several cancers are caused due to infections. They can be caused by viral, bacterial or parasitic infections. The common infections responsible for causing cancer are human papillomavirus (HPV), the bacterium Helicobacter pylori, hepatitis B (HBV) and hepatitis C (HCV).

  • HPV : It is a common infection, but there are certain high-risk types of virus that can result in cancers such as anal and cervical cancer. This generally spreads through intercourse.
  • HBV and HCV : Infection with these viruses can cause liver cancer. This spreads through blood and other fluids of the body.
  • H pylori : Infection with this bacterium is very common globally. Generally, children are prone to this as it is passed through contaminated food and water. It raises the risk of stomach cancer.
  • HIV : Infection of human immunodeficiency virus (HIV) makes a person more susceptible to have certain types of cancer such as Kaposi sarcoma, lymphoma, and liver.
