on any given morning, michelle materi might be found on a pickleball court, focused, determined and moving with purpose. it’s a small but meaningful ritual, one that helps her reclaim a sense of normalcy in a life transformed by a diagnosis she never saw coming.
just a few years ago, materi’s life looked very different. a mother of four boys, she worked full-time for the alberta government, played tennis several times a week, and juggled the rhythms of a busy family life. “life was good,” she recalls.
then came the headaches.
at first, they were sporadic. when they began occurring daily and became increasingly painful, materi went to see her optometrist.
what followed was a rapid and disorienting cascade of appointments: imaging, a spinal tap and, within days, a referral to neurology. “the neurologist just said, ‘oh, by the way, we found a brain tumour,’” she recalls.
a life-changing diagnosis
further testing confirmed the diagnosis made by the neurologist: materi had an oligodendroglioma, a rare tumour that starts in the oligodendrocytes — cells that cover and protect nerves — found in the central nervous system (cns). this tumour is a type of glioma, a cancerous tumour that originates in the brain’s glial cells, which support and protect the cns’s neurons and are essential for brain function.
for patients, the word “glioma” can feel both unfamiliar and terrifying. as dr. jacob easaw, a medical oncologist at the cross cancer institute in edmonton, explains, gliomas are not staged based on how far they spread, like many other cancers. instead, doctors grade them based on how aggressive the cells look under a microscope.
“at the simplest level, when one of those support cells becomes cancerous — or, in medical terms, malignant — we call it a glioma, he says.

gliomas are rare tumours that affect about five to six per 100,000 canadians each year. oligodendroglioma, the type michelle was diagnosed with, represents only a small fraction of these cases. despite their rarity, these tumours can have a profound impact. symptoms may include headaches, vision changes, seizures, or difficulty speaking, often prompting urgent medical evaluation.
