Mei-Ling Lancashire was diagnosed with triple-negative breast cancer two years ago.
The 43 year old single mum of 2 is a senior partner at a GP surgery in Surrey Heath.
She is one of the stars of the charity’s ‘Together We Are Beating Cancer’ campaign.
Her face features on a TV advert as well as billboards and posters on display and across the UK.
The campaign launch coincides with new data released by Cancer Research UK today.
It shows around 1.2 million deaths have been avoided in the UK since the mid-80s, due to progress in cancer prevention, diagnosis and treatment.
