Parents have the legal right to withdraw their child from a clinical trial at any time, for any reason. But before doing so, it’s a good idea to discuss questions or concerns with your child’s oncologist. The decision to withdraw from a trial should not be held against the parent, and the child will still receive the best available care for his type of cancer. On the consent form signed by the parent, there will be language similar to this: “You are free not to have your child participate in this research or to withdraw your child at any time without penalty or jeopardizing future care.”
