What Is the Most Common Virus That Causes Cancer? HPV causes more cancers worldwide than any other virus — but it is only one of several infections capable of contributing to human cancer. Cancer is usually thought of as a disease of damaged genes. But sometimes the chain of events that leads to cancer begins with something entirely different: an infection. Most familiar viral infections are not associated with cancer. The viruses that cause the common cold, influenza viruses and coronaviruses such as SARS-CoV-2 are not established cancer-causing viruses. But a small group of viruses can, under the right circumstances and often over many years, contribute to the development of cancer. Among them, HPV is responsible for the largest number of cancer cases worldwide. According to the International Agency for Research on Cancer (IARC), almost 750,000 new cancer cases worldwide in 2020 were attributable to HPV infection. HPV is not alone. Hepatitis B and C viruses can cause li...

Jian Zhou: The Scientist Who Helped Make the HPV Vaccine Possible He lived long enough to see the vaccine reach clinical trials — but not long enough to see how far it would eventually go. ⏱ In 30 Seconds ✓ Jian Zhou was a Chinese-born virologist who worked with Ian Frazer, Xiao-Yi Sun and colleagues on research that helped make HPV vaccination possible. ✓ In 1991, Zhou was first author of a landmark study showing that HPV16 capsid proteins could assemble into virus-like particles (VLPs) , a crucial principle behind modern HPV vaccines. ✓ Zhou died unexpectedly in 1999 at just 42 years old , when vaccine development based on the research had already reached clinical trials. ✓ He never saw HPV vaccines become a global cancer-prevention tool. Ian Frazer later described Zhou as an “equal partner” in much of the HPV vaccine development work. In 2006, one of the most remarkable ideas in cancer prevention became a medical reality. A vaccine against human papillomavirus (...
