Here are some questions to ask before you agree to take part in a clinical trial: Why is the clinical trial being done?      How will it help me?      What kinds of tests and treatments are part of the trial? How could the clinical trial change what I do every day? What will happen to my cancer with or without this treatment? What treatments could I get if I don't take part in the clinical trial? What are possible short- and long-term side effects for me and my family to think about?      How do the risks and side effects of the standard treatment compare with the new treatment? How long will the clinical trial last? Will I have to stay in the hospital during the clinical trial? If so, how often and for how long?      Will I have check-ups after the clinical trial? How long do I have to make up my mind about joining this trial? Tip: Write out a list of your questions and concerns to ask your doctor
