Alan Carr and Davina McCall are among the famous faces helping to launch new Channel 4 fundraiser Stand Up To Cancer.

Channel 4 has joined forces with Cancer Research UK for the new national event to raise money in fight against cancer.

Embarrassing Bodies’ Dr Christian Jessen will also take part in a week of factual and health programmes, to be screened on the channel in October, culminating in a live fundraising extravaganza.

Since Stand Up To Cancer (SU2C) launched in the US in 2008, it has raised more than £100 million for cancer research projects.

Actress Gwyneth Paltrow will be executive producer on the third US-based telecast which takes place on September 7, and will also take part in the London launch event for the Channel 4 season.

Gwyneth said: “Like so many people all over the world, I know what it’s like to lose a loved one to cancer; it took my Dad in the prime of his life. Stand Up To Cancer has the power to revolutionize the way we fight this disease, by uniting doctors, scientists and patients in groundbreaking research.

“This special broadcast will mark a wonderful milestone as SU2C evolves into a true global movement.”

Jay Hunt, chief creative officer of Channel 4, added: “Sadly most of us – more than one in three – will be touched by cancer at some point in our lives.

“Stand Up To Cancer is about doing what Channel 4 does best – focusing attention on an important issue using entertainment and comedy. We hope to raise vital funds for trials that could save lives.”
