Theo Burrell, 36, has shared her "tumour will return and it will kill me" one year on from receiving a devastating diagnosis.
The antiques expert says she fears she "only has a year or two left" after being told she has an aggressive grade 4 glioblastoma last year.
Theo, who joined the Antiques Road show team in 2020, took to Instagram on Wednesday to share how her employer Lyon and Turnbull Auction House are currently running an online fundraising auction to raise funds for The brain Tumour Charity.
"It's day two of Piece of Mind: The Brain Tumour Charity auction which we're running @lyonandturnbull in aid of @thebraintumourcharity," the 36-year-old told her followers.
"This time last year I was diagnosed with an incurable aggressive grade 4 brain tumour. Since then I've had surgery, radiotherapy and chemotherapy to keep the cancer under control. But my friends and I are doing something positive in light of this by running a fundraising auction - with many incredible lots!"
"Despite 12,000 people being diagnosed every year with a primary brain tumour, survival rates have barely improved in 40 years," Theo's employer Lyon and Turnbull Auction House write in the introduction for the online auction.
Brain tumours are the biggest cancer killer in children and adults under 40, yet investment in research is low, and there is currently no cure. The Brain Tumour Charity is working faster, and going further, to try and beat this cancer sooner.
Speaking to The Sun, Theo added: "Receiving my diagnosis, at the age of 35, when my son was one year old, was devastating.
"Overnight everything had changed. Suddenly I’d gone from being a healthy person in the middle of my life with a new baby to having incurable cancer with maybe only a year or two left to live.
What followed was months of surgery and treatment to try and prolong my life.
"And although I continue to make the best of each day, my tumour will return and it will kill me."
She continued to praise the care she has received so far but stressed how fundraising is crucial in order to find a life-saving cure.
