Nov 12, 2024 · Viruses can also cause inflammation or alter the immune system, making it more difficult to fight cancer cells. There are several viruses associated with cancer, including human papillomavirus (HPV), human immunodeficiency syndrome (HIV), hepatitis B and C, Epstein-Barr, and a few more.
Infectious cancer agents (including, viruses, bacteria and parasites) have been divided into two broad categories: direct carcinogens, which express viral oncogenes that directly contribute to cancer cell transformation, and indirect carcinogens that presumably cause cancer through chronic infection and inflammation, which eventually leads to ...
This review aims to summarize some of our current knowledge of cellular transformation and cancer progression induced by viruses and bacteria and attempts to join previously described virus-related mechanisms with newly discovered bacterial-related mechanisms.
Eventually the cancer cells penetrate the wall of the colon and invade other abdominal organs, such as the bladder or small intestine. In addition, the cancer cells invade blood and lymphatic vessels, allowing them to metastasize throughout the body.

Mar 1, 2024 · The changes to how infected cells grow and how KSHV persists put cells at a much higher risk of forming tumors and play a crucial role in causing cancer. The team showed the virus activates a specific pathway driving cell metabolism and proliferation.
