Parental Treatment Refusals: What Your Responsibilities Are When Mom and Dad Decline Cancer Treatment for a Child

Get Permission

In April 2019, a 3-year-old boy, Noah McAdams, missed the third round of chemotherapy for his acute lymphoblastic leukemia. His parents wanted instead to focus on alternative remedies of cannabidiol oil, alkaline water, mushroom tea, and herbal extracts. The sheriff was summoned; Noah’s parents lost custody of their son, and a judge ruled that Noah must continue treatment despite his parents’ wishes.1

This case is not unique. Media headlines regularly report police actions and court proceedings involving parents who refuse cancer treatment for their children.2-4 Indeed, these cases are becoming more common as parents increasingly pursue alternative medicine or faith healing instead of conventional treatment.5,6 Therefore, oncologists must understand their legal responsibilities in these situations.

Children Generally Cannot Consent to Their Own Cancer Treatment

Cancer treatment for children almost always requires parental consent. Minor patients (those younger than age 18) are generally presumed incompetent, thus legally incapable of providing consent to their own medical treatment. Therefore, parents must make treatment decisions on their behalf.7

However, there are three exceptions to this general rule. First, “emancipated minors,” like adult patients, may make their own health-care decisions. Minors become emancipated by joining the military, getting married, obtaining a court order, or demonstrating the ability to live independently and to manage their own financial affairs.8 Second, even when unemancipated, some states permit “mature minors” to make their own health-care decisions if they demonstrate sufficient understanding and appreciation of the nature and consequences of treatment despite their chronologic age.9-11 Third, even when neither emancipated nor a mature minor, almost all states permit minors to consent to certain types of treatment concerning contraception, abortion, sexually transmitted infections, mental illness, and substance abuse. States are now debating whether to add vaccination.12

Parents Must Act in the Minor Patient’s Best Interest

Notwithstanding these exceptions and the value of minors participating in their own health care, parents usually remain the final decision-makers.7 Parents must act in the child’s best interest. This does not require that parents choose objectively “literally best” options for the patient. Instead, the best interest standard requires only that parents choose what they themselves “think” is best for the patient. Parents have a wide “zone of discretion.”13 They may make suboptimal decisions. They may even refuse potentially life-saving therapy when it is unlikely to be effective or when the side effects are overly burdensome.

Although wide, the zone of discretion is not unlimited. Parents may not refuse cancer treatment when (1) withholding treatment poses a significant risk of serious irreparable harm and (2) the projected benefits of the refused treatment outweigh the burdens.14,15

Here are two examples. The parents of 12-year-old Sarah Hershberger stopped chemotherapy for her T-cell lymphoblastic lymphoma. Because Sarah had an estimated 85% chance of eliminating her cancer with treatment, the court appointed a guardian to make medical decisions.16 Similarly, the parents of 17-year-old Cassandra Callender refused chemotherapy for her Hodgkin’s lymphoma. Because Cassandra had an estimated 85% chance of survival with treatment, the court authorized the state’s Department of Children and Families to make medical decisions.17 These two cases accord with dozens of others. Well-settled jurisprudence holds that parents may not refuse therapy of proven efficacy when refusal places the minor patient at significant risk of serious harm.

Refusing Effective Cancer Treatment Is Child Neglect

Parents refuse cancer treatment for four reasons: (1) they prefer complementary and alternative medicine; (2) they have faith-based reasons; (3) they are concerned about adverse effects; and (4) they lack insight into the patient’s treatment needs.18 Yet, no matter the reason, refusing effective cancer treatment is child neglect, unless the refusal is for religious reasons in some states.19,20

Whatever the reason for refusal, the American Academy of Pediatrics advises that “clinicians have a legal and ethical responsibility to question and, if necessary, to contest” parental medical decisions that “put the patient at significant risk of serious harm.”7 Consistent with this recommendation, the largest study of its kind found that most oncologists reject parental refusals when treatment has a 33% or greater chance of success.21

Fortunately, most parent-clinician disagreements are short-lived. Clinicians can usually reach resolution by listening to the patient, listening to the parents, and offering good explanations for the recommended treatment.22 If necessary, clinicians can involve secondary consultants such as ethicists, psychologists, chaplains, or palliative care in the discussion. Multidisciplinary meetings often clarify misunderstandings and help everyone reach consensus.

Clinicians Must Report Suspected Child Neglect to State Authorities

However, when informal conflict resolution is not possible, clinicians must report suspected child neglect due to treatment refusal to state authorities. Oncologists have a duty to report these incidents when they have a “reasonable suspicion” or “reasonable cause to believe” that the information is reportable. Depending on the state and on the type of information, the report is typically made either to law enforcement or to a state agency. Failure to report can result in three types of sanctions: criminal penalties, civil penalties, and discipline from the clinician’s health licensing board.23

Although underreporting often leads to sanctions, overreporting rarely does, because clinicians have legal immunity for making a good faith report. Even if they are mistaken, clinicians cannot be sanctioned for breaching confidentiality or for prompting an ultimately unnecessary investigation. Consequently, existing legal incentives lean heavily in one direction. They encourage clinicians to err on the side of caution and report parents who refuse medical treatment for their child.23 In short, if you are in doubt, if you are unsure whether an incident is reportable, then it probably is. ■
