The popular Scottish actor, who is currently filming the next series of Dr Who, is a patron of the charity.

David also met with a young doctor whose pioneering work is being funded by the AICR.

Dr Andy Tee, who comes from Dundee, has been awarded £750,000 by the charity to continue his ground-breaking work into the study of tuberous sclerosis complex (TSC), a condition which affects one in 7000 births, and in which tumours (mostly benign) form in the brain, lungs, kidneys, hearts and eyes of babies and young children.

Dr Tee is a self confessed Dr Who fanatic and was delighted to meet the star of the popular show.

"David was keen to hear about my work and why the funding grant from AICR is so important in allowing me to continue my research," he said.

After being photographed together, David commented: "It was good for me to meet a real life superhero whose work holds the prospect of helping many thousands in their fight with cancer".

AICR's Chief Executive, Norman Barrett, thanked David for giving up his valuable time to appear in the video.

He added: "His help and support will help bring the important work of AICR to a wider audience.

''We are proud to support some of the world's greatest cancer experts, but we are also committed to helping young scientists at the start of their career.

''We are also delighted to have awarded Dr Tee an AICR research fellowship. We pride ourselves that we champion the brightest and best".
AICR (Association for International Cancer Research) is a totally independent charity which has no commercial ties, no links with any particular research institutions and no commitment to follow any particular line of research. It funds what it considers to be the best researchers and the most valuable studies, wherever they are in the world."
