Examining liver cancer using the co-carcinogenesis hypothesis

Liver cancer

Francis Peyton Rous' Co-carcinogenesis hypothesis: that a virus and a carcinogen together cause cancer. (1966 nobel prize)

What I surmise from his hypothesis:

A virus enters a cell through a receptor, opens up and alters host DNA telomeres. The carcinogen with a benzene ring inhibits the virus' polymerase because viral polymerases have stronger binding affinities than the host's.


Cancer cells can make unlimited copies because of the telomere modifications. Co-carcinogenesis requires a virus and a carcinogen to start the cancer. The cancer tumor wears the entry receptor on the surface.

alcohol as a carcinogen in liver cancer

Hepatitis viruses as the triggers: means there should be at least 3 types of liver cancer (hepatomas)

Hepatitis A is an enterovirus
Hepatitis B is a polyomavirus
Hepatitis C is a flavivirus

hepatitis B as a polyomavirus would use serotonin  receptors

hepatitis C as a flavivirus would use the melanocortin receptors

Angiosacrcoma is a liver cancer of the liver's blood vessels

Angiosarcoma has arsenic as the carcinogen.

hepatitis A as an enterovirus would use the acetylcholine receptors

as a cytosolic RNA virus...enteroviruses would not cause cancer.

these receptors are located in the blood vessels of the liver
