Last year, former Culture Secretary Dame Tessa Jowell was diagnosed with a brain tumour. It is a type of cancer that is becoming more common, and the UK has the lowest survival rates in Western Europe. Three in four people diagnosed with this type of brain cancer in Britain are dead within a year.

After her diagnosis, Tessa Jowell and her daughter Jess launched a campaign for brain cancer patients to get access to more trials and treatments than are currently available on the NHS.  

With intimate access during the final weeks of her life, this moving film for BBC1 Panorama follows Tessa as she tries to use her influence to highlight the struggles of brain cancer patients across the UK, and bring about a radical and permanent change in NHS cancer treatment.
