Five-year-old Marcel dies from aggressive brain tumour

Five-year-old Marcel has died from an aggressive brain tumour.

He died about a month and a half after his diagnosis, according to one account.

His family said he had set off on his “great space journey,” using language that framed his death as a journey.

Treatment could no longer help Marcel, according to another account.

His family says it will continue its fight against childhood cancer.

Marcel’s mother plans to make that work her life’s mission.
