Viruses are one of the most important risk factors for cancer development in humans. [2] Infection by some hepatitis viruses, especially hepatitis B and hepatitis C, can induce a long-term viral infection that leads to liver cancer in about 1 in 200 of people infected with hepatitis B each year (more in Asia, fewer in North America), and in ...
Men who have had a gonorrhea infection have a risk of having prostate cancer. [65] Guillain–Barré syndrome: Guillain–Barré syndrome is associated with the bacterium Campylobacter jejuni, and with the viruses cytomegalovirus [66] and enterovirus. [67] Irritable bowel syndrome
Worldwide, approximately 18% of cancer deaths are related to infectious diseases. [3] This proportion ranges from a high of 25% in Africa to less than 10% in the developed world. [3] Viruses [66] are the usual infectious agents that cause cancer but bacteria and parasites may also play a role. Oncoviruses (viruses that can cause human cancer ...
Some infectious agents are linked to increased risk of cancer in their host organisms. The articles in this category pertain to such infectious agents, the vaccines that prevent infection by these agents, the names of the cancers linked to, associated with, caused by and/or have an increased risk of developing from these infectious agents.
Bacteria involved in causing and treating cancers. Cancer bacteria are bacteria infectious organisms that are known or suspected to cause cancer. [1] While cancer-associated bacteria have long been considered to be opportunistic (i.e., infecting healthy tissues after cancer has already established itself), there is some evidence that bacteria may be directly carcinogenic.
Worldwide, approximately 18% of cancer cases are related to infectious diseases. [9] [60] This proportion varies in different regions of the world from a high of 25% in Africa to less than 10% in the developed world. [9] Viruses are the usual infectious agents that cause cancer but bacteria and parasites also contribute. Infectious organisms ...
HPV infection is common among healthy individuals and is acquired through oral sex. Although less data is available, the prevalence of HPV infection is at least as common among men as among women, with 2004 estimates of about 27% among US women aged 14–59. [8] HPV oral infection precedes the development of HPV+OPC.
