Research
While studying tuberculosis in lab rats, Fibiger found tumors in some of his rats. He discovered that these tumors were associated with parasitic nematode worms that had been living in some cockroaches that the rats had eaten. He thought that these organisms may have been the cause of the cancer. In fact, the rats had been suffering from a vitamin A deficiency and this was the main cause of the tumors. The parasites had merely caused the tissue irritation that drove the damaged cells into cancer; any tissue irritation could have induced the tumors.
Although the specific link between the parasites and cancer was later known to be relatively unimportant, it was discovered later that tissue damage was a cause of cancer. This was an important advance in cancer research. Other parasites (such as Schistosoma haematobium and Clonorchis sinensis) are now known to cause cancer in humans.
One of his experiments from 1898 is by some regarded as the first controlled clinical trial.

Famous quotes containing the word research:
“Our science has become terrible, our research dangerous, our findings deadly. We physicists have to make peace with reality. Reality is not as strong as we are. We will ruin reality.”
—Friedrich Dürrenmatt (19211990)
“The great question that has never been answered, and which I have not yet been able to answer, despite my thirty years of research into the feminine soul, is What does a woman want? [Was will das Weib?]”
—Sigmund Freud (18561939)
“The research on gender and morality shows that women and men looked at the world through very different moral frameworks. Men tend to think in terms of justice or absolute right and wrong, while women define morality through the filter of how relationships will be affected. Given these basic differences, why would men and women suddenly agree about disciplining children?”
—Ron Taffel (20th century)
