When you take part in a clinical trial, you receive your treatment in a cancer center, hospital, clinic, and/or doctor’s office.  Doctors, nurses, social workers, and other health professionals may be part of your treatment team.  This team will follow your progress very closely.  You may have more tests and doctors visits than you would if you were not taking part in a study.  You will follow a treatment plan your doctor prescribes, as specified by the trial protocol, and you may have other responsibilities such as keeping a log or filling out forms about your health.  Some studies continue to check on patients even after their treatment is complete.
