The family, which can't be named to protect the boy's identity, told a family court Tuesday they won't fight the treatment until the current round of chemotherapy ends this week. They were given court permission to seek more medical opinions, The Hamilton Spectator reported.

Last week, the Children's Aid Society took custody of the boy as he was having a hospital examination for his acute lymphoblastic leukemia, diagnosed when he was 7.

His father contacted media outlets, claiming the boy had decided he didn't want any more chemotherapy and wanted less intrusive treatment.

"He's a little prisoner. He can't leave his room or anything," the father described his son to reporters.

In prior court challenges, pediatric oncologists said the boy would only live six months without chemotherapy and another round of drug treatment would give him a 50-50 chance of complete remission.
