Mrs Jean Williams wishes to help the charity put pressure on politicians to act upon future cancer challenges, believing that this could make a huge difference to future survival rates.
With the Cancer In Scotland strategy to expire in 2011 and the NHS Cancer Plan for England to run out in 2010, none of the UK's four nations have devised policies to take cancer strategies beyond these years, as neither Wales nor Northern Ireland have implemented strategies for fighting against the disease.
Cancer Research UK is now calling for comprehensive cancer strategies to be devised to run until at least 2020, a move which is thoroughly backed by Jean.
The charity's 'Cancer 2020: Plan it right, make it fair' petition, which insists that the disease does not slip down the political agenda, has been signed by Jean, who was diagnosed with breast cancer in 1997.
After enduring a double mastectomy, chemotherapy and radiotherapy, Jean is currently in remission and is undergoing reconstruction surgery.
She explained: "More and more people like me are surviving cancer, which is obviously fantastic news.
"But society must not get complacent.
"Positive survival rates are tempered by the fact that cancer incidence is on the rise as well.
"This is because cancer is predominantly a disease that affects older people, and, as more people are living longer, an increasing number are developing cancer."
Jean added: "Addressing this growing cancer challenge will depend on rigorous planning, which is why I am joining Cancer Research UK in calling on politicians to develop comprehensive cancer strategies expanding until at least 2020."
The King's Fund, an independent health think tank, recently released a report which supported the call for updated cancer strategies.
The report, which was commissioned by Cancer Research UK, said the NHS Cancer Plan must be updated to accommodate the ageing population, technological advances and reforms in NHS Structures which have been implemented since the Plan was published six years ago.
The ageing population will increase the number of people diagnosed with cancer, whilst technological advances will result in more people living with cancer.
Professor Alex Markham, Cancer Research UK's chief executive, said: "Thanks to the NHS Cancer Plan of September 2000, cancer services in England have undergone a transformation.
"Survival rates are climbing, death rates are falling, and more patients than ever before are being treated in clinical trials.
"These are just some of the important improvements that have been achieved, but we need the government to act now if the momentum is to be sustained beyond 2010, when the current Plan comes to an end.
"In Scotland too, ministers need to start planning now, as the Cancer in Scotland strategy ends in 2011."
He continued: "An ageing population, a higher incidence of cancer, and more sophisticated and expensive treatments all mean that now is precisely the time when the NHS should be raising its game.
"If patients are going to benefit from the advances that Cancer Research UK's vital works contributes to, then it's essential politicians start considering their strategies for the future now.
"I would strongly encourage people to sign our 'Cancer 2020' petition and add their voice to our vital campaign."
With more and more effective treatments being developed, thanks to research carried out by organisations like Cancer Research UK, the cost of these expensive drugs needs to be met, which is one of the major challenges politicians encounter.
However, the campaign does not focus uniquely on individual drugs and individual patients' attempts to access particular treatments.
On a broader scale, Cancer Research UK believes that all patients, regardless of where they may live, should be provided with the most clinically-appropriate and cost-effective treatment available.
The 'Cancer 2020: Plan it right, make it fair' petition has so far accumulated nearly 200,000 signatures, which will be presented to ministers in Scotland, England, Wales and Northern Ireland early next year.
Those wishing to sign the petition can do so by visiting www.cancer2020.org, texting 'CAMPAIGN' to 64118, or signing a paper sheet in any Cancer Research UK shop.
