Questions to Ask Your Doctor


If you are considering participating in a cancer clinical trial, it is important to know as much as possible about the study before your agree to participate. The informed consent process should provide answers to many of your questions.  However, you should feel comfortable asking your doctor and research team any other questions you may have and be able to receive further clarification on something that was already explained.

Here are some questions you may want to ask and discuss with your health care team.  Being well informed is very important in the decision making process of whether to participate in a cancer clinical trial.
