About Glioblastoma Awareness Day
Glioblastoma Awareness Day takes place on Wednesday, 15 July 2026. It is a day dedicated to raising awareness of glioblastoma, the most common and aggressive form of malignant brain tumour in adults, and to honouring the patients, families, researchers, and caregivers affected by it. The observance falls on the third Wednesday of July each year.
What is Glioblastoma Awareness Day?
Glioblastoma Awareness Day is an annual day of recognition that highlights the devastating impact of glioblastoma, also known as GBM, and the urgent need for greater research and funding. It is supported by the National Brain Tumor Society and other leading brain tumour organisations in the United States. The day provides an opportunity to remember those lost to the disease, support those currently living with it, and call for progress in treatment for a cancer that has seen few breakthroughs in decades.
When is Glioblastoma Awareness Day?
Glioblastoma Awareness Day is observed on the third Wednesday of July each year. In 2026, that date is Wednesday, 15 July. Because the date is tied to a weekday pattern rather than a fixed calendar date, it shifts slightly from year to year. The United States Congress has marked the occasion through resolutions in successive years recognising the third Wednesday of July as Glioblastoma Awareness Day.

Why Glioblastoma Awareness Day Matters
Glioblastoma is among the most aggressive of all cancers. It accounts for roughly 35 to 40 percent of all cancerous brain tumours and is diagnosed in about 14,000 people in the United States each year. The prognosis remains grim: most patients survive on average just 12 to 18 months after diagnosis, and the five-year survival rate is only around 5 percent. Despite decades of research, effective treatments remain limited, which is why awareness and fundraising are so vital. The day helps drive public attention, encourages donations to research, and reminds policymakers that this disease demands greater investment.
How to Get Involved in Glioblastoma Awareness Day
There are many meaningful ways to take part:
- Wear grey – Grey is the colour associated with brain tumour awareness, so wearing it is a simple way to show support and start conversations.
- Donate to research – Contributing to organisations such as the National Brain Tumor Society directly funds the search for better treatments.
- Share survivor and patient stories – Amplifying real experiences on social media helps others understand the human impact of the disease.
- Learn the warning signs – Familiarise yourself with symptoms such as persistent headaches, vision changes, nausea, and difficulty speaking.
- Support a caregiver – Offer practical help to families caring for someone with glioblastoma, who often carry an enormous burden.
- Take part in a fundraising event – Join a walk, run, or community event raising money for brain tumour research.
- Advocate for funding – Contact representatives to encourage continued government investment in cancer research.
- Light a candle in memory – Many families use the day to remember loved ones lost to the disease.
History of Glioblastoma Awareness Day
Glioblastoma Awareness Day was established to give a dedicated focus to one of the deadliest forms of cancer. It is championed by the National Brain Tumor Society together with a coalition of brain tumour advocacy organisations in the United States. The day grew out of the wider brain tumour awareness movement and was given formal recognition through resolutions passed in the United States Senate and House of Representatives.
Each year, Congress has reaffirmed the observance, designating the third Wednesday of July. For 2026, House Resolution 1270 expressed support for designating 15 July 2026 as Glioblastoma Awareness Day. These resolutions help raise the profile of the disease at a national level and signal political recognition of the need for more research.
The day has gained particular public attention in recent years following the deaths of several high-profile figures from glioblastoma, which brought wider awareness to a cancer that many people had never heard of before.
