Clinical trials are medical research trials involving people. Volunteers for trials can include healthy people or patients. People take part in trials in all areas of medicine, not just in cancer and not just to test treatments. For example, a clinical trial may be used to compare different ways of diagnosing an illness. Or it might look into whether it’s possible to prevent a particular cancer.
Doctors and patients need evidence from clinical trials to know which treatments are the safest and most effective.
This information is for people with cancer, who may have the option of joining a clinical trial as part of their cancer treatment. We refer to these people as patients.
