Online Resource: National Cancer Institute

The National Cancer Institute, the United States federal institute for research on cancer, has an extensive website for both those touched by cancer and for researchers.

On the website, there are links to information on different cancers- both on prevention and treatment. There is a glossary of cancer terms as well as an official drug dictionary. They also include a nice introduction and resource list about Complementary & Alternative Medicine.
