Groundbreaking Discoveries in Cancer Causation

Dr. Gillison's work linking HPV to throat cancer is part of a broader history of groundbreaking discoveries in understanding cancer's origins, including the role of other viruses and genetic factors.

The top 3

1. Viruses as Cancer-Causing Agents: Peyton Rous's discovery in 1911 of a virus causing sarcomas in chickens laid the groundwork for understanding oncogenic viruses, a field further advanced by linking Epstein-Barr virus, Hepatitis B/C, and HPV to human cancers.
2. Genetic and Cellular Basis of Cancer: Theodor Boveri proposed in 1902 that tumors arise from single cells with chromosome damage, a concept refined by later discoveries of oncogenes and tumor suppressor genes in the mid-20th century.
3. Ancient Viral DNA's Role in Cancer Growth: Recent research indicates that DNA fragments from ancient retroviruses, integrated into the human genome millions of years ago, can act as 'on switches' for genes that promote tumor growth in various cancers like colorectal, lung, and stomach.
