Answer:
After graduating from Friedrich-Wilhelms University in Berlin in 1843, his major work was in pathology, becoming its professor in Pathological Anatomy and Physiology in 1854. He developed an interest in microscopy. His first scientific paper was two years after graduating, on the pathological description of leukaemia, a term he invented. On the back of the recent discovery by Theodor Swann that all animals are composed of cells, he became convinced of their importance, declaring: “The body is a cell state in which every cell is a citizen. Disease is merely the conflict of the citizens of the state brought about by the action of external forces,” and that “every cell arises from another cell.”
Virchow was the first to correctly link the origin of cancers from otherwise normal cells, believing that cancer is caused by severe irritation in the tissues (the ‘chronic irritation theory’). Not all of his work was correct, however. He also proposed that cancer spreads around the body by the spread of the irritation in liquid form. And his diagnosis of benign laryngeal ulceration in the German Emperor, Kaiser Friedrich III, prevented the emperor undergoing surgery, who then subsequently died of metastatic laryngeal squamous cell carcinoma. Virchow was accused of malpractice; however, recent reassessment suggests that he was at least partly correct.
