'My name is Grant Stewart and I am a junior doctor from Edinburgh following a career in urology. I am currently undertaking research into prostate cancer, investigating a molecule thought to play a role in the survival and spread of prostate cancer cells.
As well as a surgical trainee I have been running seriously since I was 12 years old. I am still able to compete to a high level and as such get an elite entry for the Great North Run - the world's largest half marathon race, with 50,000 runners this year.
It is particularly difficult to secure funding for prostate cancer research which, despite being the commonest male cancer and second commonest cause of male cancer related deaths, has a poor level of public awareness and research funding.
Because of this I raised some money for Prostate Research Campaign UK. My parents really got stuck in too, organising a big coffee morning. So far we have raised £1,165 and the money is still rolling in.
