Antiques Roadshow's Theo Burrell has admitted that she felt 'flattened' by chemotherapy as she shared an update on her 'hard to accept' terminal cancer diagnosis.

The 38-year-old, who joined the BBC show in 2018 to share her expertise in decorative arts and fine antiques, was diagnosed with aggressive grade four glioblastoma in 2022.

'Glioblastoma is a type of cancer that starts as a growth of cells in the brain or spinal cord. It grows quickly and can invade and destroy healthy tissue. Glioblastoma forms from cells called astrocytes that support nerve cells,' according to Mayo Clinic. 

She has kept fans up to date with her health throughout the past three years, and in recent weeks opened up about how chemotherapy had taken its toll.  

According to Survivor Net, Theo said on an Instagram post: 'The fatigue from the chemo has really flattened me over the last couple of weeks, with regular headaches rearing their ugly heads.

'I also had a seizure-like episode where my vision went funny, which ultimately resulted in me being checked over in the hospital.'

'Chemotherapy is a common cancer treatment that uses medicine to kill cancer cells,' the NHS website states. 

The drug can be taken a number of ways: a tube into a vein, an injection, a wearable pump or tablets.

The TV star's last health update was back in September.

Theo told fans on Instagram: 'A couple of weeks ago I got the news that my scans continue to be clear!

'There are no active cancer cells rearing their ugly heads, and Temozolomide continues to do its job.

'I'm extremely lucky to have gotten to this stage, with this news.

'However, despite the positive update I've had an extremely tough time on cycle 10 of chemotherapy, following a small visual seizure. 

'The combination of the two had me in bed for days on end, with new side effects which challenged me both mentally and physically.'

Theo's fans rushed to the comments section in September to share their love and support when she shared her health update
