Growing Up With Cancer, 7.30pm, BBC1

EVERY day in the UK, seven teenagers are told they have cancer. This candid and deeply moving film meets some of the brave young patients being treated in the Teenage Cancer Trust Unit at Glasgow’s Royal Hospital for Children. Even as he is diagnosed, Nairn, 14, (pictured with Natasha McNeil) is determined to keep smiling for his parents’ sake. Astonishing.
