Allyson founded Ovarian Cancer Action in 2004, as a campaigning voice for women with ovarian cancer - lobbying for greater understanding of its complexities and investigating symptoms awareness and late diagnosis.
In September 2013, Allyson was appoint Chair of Cancer52, an alliance of some 70 cancer charities working in the less common and rare cancer field.
On news of her appointment, Allyson said: "It was a wonderful surprise to open the letter from the Cabinet Office and see that I had been nominated for this award."
Jane Lyons, CEO of Cancer52 said: "I am very pleased that Allyson's work has been recognised in such a wonderful way. She has worked tirelessly for women with ovarian cancer and we now welcome her commitment and expertise as she applied her knowledge across a wider range of cancers to support us at Cancer52."
