When Parents Refuse Chemotherapy: Four Children, Four Courts

Childhood cancers are among the great successes of modern medicine, and the cure depends on finishing treatment. When parents say no — out of fear, faith, or a promise from an alternative healer — a court is asked to decide. These are four cases from Saskatchewan, Utah, Minnesota and Ontario, and what the courts actually did.

Tyrell Dueck, Saskatchewan, 1999

Tyrell had osteosarcoma in his leg. His doctors recommended chemotherapy and amputation, with a good chance of survival if he finished treatment. He and his parents, supported by fundamentalist religious backers and an alternative-cancer network that included Ottawa's Canadian Cancer Research Group, refused. A Saskatchewan court found that at 13 he was not able to make the decision and ordered treatment. Within weeks the cancer was found to have spread to his lungs, his doctors said treatment would no longer change the outcome, and the order lapsed. His family took him to a Tijuana clinic for laetrile, vitamins and shark cartilage. He died on 30 June 1999. The full Dueck record →

Parker Jensen, Utah, 2003

A growth under 12-year-old Parker's tongue was removed and found to be Ewing's sarcoma — confirmed by Primary Children's Medical Center in Salt Lake City, and later by Children's Hospital Los Angeles. At least four doctors recommended chemotherapy. His parents, Daren and Barbara Jensen, feared it would stunt his growth and leave him sterile. When a juvenile court ordered him into treatment by 8 August 2003, the family went to Idaho, and Utah took legal custody that day.

The Jensens were charged with kidnapping, a first-degree felony. In October 2003 the charge was reduced to misdemeanour custodial interference, held in abeyance for a year. An Idaho oncologist who examined Parker under an interim agreement also recommended eleven months of chemotherapy. The parents refused again, and on 1 October 2003 the state dropped its efforts, concluding that chemotherapy could not work with parents determined to resist it.

The Jensens then sued the doctors and state officials personally. Federal and state courts dismissed the suits; the Utah Supreme Court ended the case in March 2011. Parker, by then 20, was serving a church mission in Chile and reported to be well.

One survivor is not evidence. Parker Jensen survived without chemotherapy after his tumour was surgically removed. Some patients do. That is why oncologists speak of chances, not certainties, and it is why the decision is so hard. His survival does not show the chemotherapy was unnecessary for him, any more than Tyrell Dueck's death shows the opposite about laetrile. It does mean his case is cited constantly by people who want parents to refuse.

Daniel Hauser, Minnesota, 2009

Daniel, 13, had Hodgkin lymphoma — one of the most curable childhood cancers, with survival above 90 per cent when treated. After one round of chemotherapy his family stopped, citing their beliefs and their membership in a self-described Native American healing organization, the Nemenhah Band. Judge John Rodenberg of Brown County District Court ordered treatment to continue. In May 2009 Daniel's mother, Colleen Hauser, fled with him; a search extended into Mexico before they returned about a week later.

Daniel resumed chemotherapy, finished it in September 2009, and completed twelve radiation sessions that November, after which the judge closed the case. His family said he had been in remission for some time.

J.J., Six Nations of the Grand River, Ontario, 2014–2015

J.J., 11, had acute lymphoblastic leukaemia — a cancer cured in the great majority of children who complete treatment. Her mother stopped chemotherapy at McMaster Children's Hospital and took her to an alternative treatment centre in Florida. The hospital asked the Ontario Court of Justice to have the children's aid society intervene.

In November 2014 Justice Gethin Edward declined. He found that the family's use of Haudenosaunee traditional medicine was a constitutionally protected Aboriginal right, which could not be limited to remedies proven by Western medicine, and that J.J. was not a child in need of protection. The decision was widely criticized by physicians and legal commentators for treating the right as if it could override the child's survival.

J.J.'s cancer returned in March 2015. Her family decided to resume chemotherapy while continuing traditional medicine. On 24 April 2015 the court issued an addendum, on a joint submission from all the parties, stating that the child's best interests are paramount, that respecting the Aboriginal right is part of deciding those best interests, and that Haudenosaunee people have the same right as anyone else to provincial health care.

Between those two rulings, on 19 January 2015, another Six Nations girl, Makayla Sault, also 11 and also with leukaemia, died after leaving chemotherapy for the Hippocrates Health Institute in Florida. No court was asked to intervene in her case.
