Sarah Beeny to open up on breast cancer and her family in Channel 4 documentary

Sarah Beeny is set to open up on her breast cancer treatment and her family's history with the disease in a Stand Up To Cancer documentary for Channel 4.

The one-off programme, Sarah Beeny: Breast Cancer, My Family and Me, will detail the TV presenter's diagnosis and treatment for breast cancer and the many emotions it stirs up as she reflects on her own mother's death from breast cancer.

When Beeny, 50, was diagnosed with breast cancer in August, it appeared to come as a complete surprise but she admits that she had been expecting the whose breast cancer spread to her brain.

Beeny looks at her own experiences of treatment as well as her mum's, and how the tough time in her life affects husband Graham and their four sons, Billy, 18, Charlie, 16, Raffey, 14, and 13-year-old Laurie in the documentary.

She said: "When I was diagnosed with breast cancer there was a moment where I considered not telling anyone in the world including my husband and children. Three minutes later I realised that wasn’t going to be possible and I was overwhelmed by the response I received – which highlighted that I was not alone in having long held a disproportionate fear of breast cancer.

"So I decided to make this documentary about how far treatment has come in the last 40 years but also about how it still affects you and those around you both mentally and physically.

"Ultimately, I want to take some of the fear out of the words ‘you have breast cancer’ and encourage people to seek help as early as possible, giving them the best chance of diagnosis and overcoming the disease."

Beeny will meet with some of Cancer Research UK's scientists who are at the cutting edge of cancer research, with the charity partnering Channel 4 in their joint high-profile Stand Up To Cancer campaign which sees celebrities and the broadcaster's shows team up to raise awareness and funds each year.

She will get the chance to find out what the future could hold for breast cancer patients, how treatment has changed in the last 40 years, and whether things could have been different for her mum if she was diagnosed today.

Kate Thomas, Channel 4's commissioning editor of daytime and features, said: "Sarah is part of our Channel 4 family, and we are awestruck at her determination to share her experience, speak openly and to help inform others who may be facing a similar diagnosis."
