You are an important member of your health care team. You should ask questions about anything you do not understand. If you need your provider to explain something in a different way, ask them to do so.
You have the right to refuse treatment if you are able to understand your health condition, your treatment options, and the risks and benefits of each option. Your doctor or other health care provider may tell you they do not think this is the best choice for you. But, your providers should not try to force you to have a treatment you do not want to have.
It is important to be involved in the informed consent process. After all, you are the one who will receive the treatment if you give your consent.
