Cancer Clinical Trails

Clinical trials are usually conducted in a progressive series of steps, called phases. The process starts with small trials testing the safety of an intervention and moves to progressively larger trials. The larger trials compare the effectiveness of the new intervention given to the investigation group to the currently accepted standard care given to the control group. Clinical trials are mechanisms for developing better methods of prevention, screening, diagnosis and treatment work better than those currently used, and whether they are safe.
