Emma Shanks, 35, of Gartocharn, Alexandria, is combining her own experience with her work as a Cancer Research UK scientist to promote the charity's message that research plays an important role in beating cancer.
Dr Shanks, who is based at the Beatson Institute at Bearsden, was first diagnosed with the life-threatening disease in 2002, aged just 22.
The cancer was spotted by her dentist in the form of an ulcer on her tongue which wouldn't heal, and Dr Shanks had laser surgery which removed a third of her tongue.
But the cancer returned in 2009 and in 2011, resulting in surgery each time.
The mum-of-two was diagnosed with tongue cancer a fourth time in April last year, when her daughter Isobel was just two weeks old.
Following an eight-hour operation, which saw a large section of her tongue removed and replaced with a graft from her forearm, there is now less than a 3% chance the cancer will return.
She said: "I know from experience that research kills cancer.
"That's why I'm supporting this vitally important campaign to help Cancer Research UK speed up the advances it is making against the disease.
"I am so grateful for the treatment that saved my life. Now I want to do everything I can to urge people to fight back against this devastating disease."
As part of her work, Dr Shanks plans to find out more about why oral cancer develops in younger people.
She said: "Success stories like mine would not be possible without the charity's life-saving work, which in turn relies on everyone who raises money."
Each hour, around three people in Scotland are diagnosed with cancer, around 29,600 people every year.
