Early Cancer Theory

Galen Headshot

Galen was a Roman physician and a believer in the Humoral Theory of Medicine proposed by Hippocrates. He believed cancer to be curable in early stages, and that advanced tumors should be operated upon either by cutting around the affected area or by cauterization. Galen thought unhealthy diet and bad climate were directly connected to cancer.1 2
