Lachie Love, an otherwise healthy eight-year-old boy who loves swimming, climbing trees, football and music, was diagnosed with a rare, incurable type of brain cancer within a week of developing a squint in his left eye.

Lachie, from Auckland, New Zealand, was diagnosed with a brain tumor on December 29 that was later confirmed to be DIPG. Diffuse intrinsic pontine glioma is an unusual, aggressive form of cancer that primarily affects children—most diagnoses are made between the ages of five and seven. In the U.S., there are about 150 to 300 new diagnoses every year.
