International Oligodendroglioma Day, known as #OligoDay, was created to raise awareness of Oligo brain cancer, and to accelerate a cure.
What is Oligo Day?
Oligo Nation launched the first International Oligodendroglioma Day (known as #OligoDay) on May 17, 2021. Before this, there was no day dedicated to bringing awareness to Oligo brain cancer.
We launched Oligo Day to tell the world we exist, and we matter.
For six consecutive years, May 17th has become a day where those impacted by oligodendroglioma are heard, recognized, and supported.
This Oligo Day, Oligo Nation asks you to help us advance critical research and bring hope to those fighting Oligo brain cancer. Whether you share your story, make a donation, attend an event, or plan one, your support makes a difference.
Together we will find a cure.

Oligo Nation
Oligo Nation is a non-profit foundation dedicated to funding medical research for
oligodendroglioma (Oligo), a rare and currently incurable form of brain cancer.
More than 20,000 Americans are living with Oligo—most diagnosed in their 20s, 30s,
and 40s—disrupting lives and families. Until recently, there was no dedicated research
focused on Oligo, but we are changing this.
This Oligo Day, Oligo Nation asks you to help us advance critical research and bring
hope to those fighting Oligo brain cancer. Learn more at oligonation.org.

Kristy & Josh Bottini
"My name is Kristy Bottini. My husband Josh was diagnosed with oligodendroglioma Grade II in December 2024. I'm his full-time caregiver and CNA and I joined Oligo Nation this year, 2026, as a fundraiser. Just being connected with so many people who know exactly what we're going through has been crazy in the best way possible. We're so happy to be a part of Oligo Nation and, funny enough, Oligo Day is on my husband Josh's birthday, May 17th. Happy Oligo Day."
