Clinical trials are research studies conducted with people.
Treatment trials test therapies in patients with cancer. These studies are very important because they often lead to the development of more effective cancer treatments. The result of such research is that many people with cancer are cured and many others have longer, more comfortable lives. These studies take place in doctors' offices, cancer centers, other medical centers, community hospitals and clinics, and veterans' and military hospitals in cities and towns around the United States and in other countries. Men, women, and children of all races and ethnic backgrounds take part in cancer treatment studies.
