He has a student who was Rudolph Virchow who was determined that cancer cells are driven from other cells. Another theory is the Chronic irritation theory. This is not a major theory. Scientist Virchow proposed that chronic irritation was the cause of cancer. But he was wrong because cancer does not spread like liquid.
