The 7 Viruses That Cause Human Cancers

  • Epstein-Barr Virus: Burkitt’s Lymphoma, Hodgkin’s Disease, and Nasopharyngeal Carcinoma. …
  • Kaposi’s Sarcoma-Associated Herpesvirus: Kaposi’s Sarcoma, Primary Effusion Lymphoma, Multicentric Castleman’s Disease. …
  • Human Adult T-cell Leukemia Virus Type 1 (HTLV-1): T-cell Leukemia.

Can a virus be a cause of cancer?

Researchers know that there are several viruses that can lead to cancer. For example, the human papillomavirus (HPV) can cause cervical and several other cancers. And hepatitis C can lead to liver cancer and non-Hodgkin’s lymphoma.

Can cancer be compared to an infectious disease?

Infectious diseases and cancer have multiple similarities. Both infectious organisms and cancer cells express many proteins that are recognizable by host T cells,1 and both elicit T-cell–mediated inflammation.

Is cancer bacterial or viral?

Today, we now know that about 15%-20% of cancers have a viral cause, including Burkitt’s lymphoma (Epstein-Barr virus), cervical cancer (human papillomavirus), and liver cancer (hepatitis B and C viruses). If, by the 1960s, viruses were accepted as a contributing cause of cancer, the same could not be said of bacteria.

What type of bacteria causes cancer?

H. pylori is the first bacterium to be termed a definite cause of cancer in humans by the International Agency for Research on Cancer. Mutagenic bacterial metabolites are also suspected to increase risk for cancer.

Do adenoviruses cause cancer?

Adenoviruses can lead to tumors in rodent models but do not cause cancer in humans; however, they have been exploited as delivery vehicles in gene therapy for diseases such as cystic fibrosis and cancer. Simian virus 40 (SV40), a polyomavirus, can cause tumors in rodent models but is not oncogenic in humans.

Can a virus cause a brain tumor?

Several types of other viruses have been shown to cause brain tumors in research on animals. More data are needed to find out if exposure to infections, other viruses, or allergens increase the risk of a brain tumor in people.

Why do cancer patients get infections?

People with cancer may have a higher risk of infection because of changes in the immune system that control their body’s defense systems. Cancer and cancer treatments can affect the immune system and other body systems in different ways.

What causes infectious disease?

Infectious diseases commonly spread through the direct transfer of bacteria, viruses or other germs from one person to another. This can happen when an individual with the bacterium or virus touches, kisses, or coughs or sneezes on someone who isn’t infected.

How do cancers spread?

When cancer spreads, it’s called metastasis. In metastasis, cancer cells break away from where they first formed, travel through the blood or lymph system, and form new tumors in other parts of the body. Cancer can spread to almost anywhere in the body. But it commonly moves into your bones, liver, or lungs.
