Four in 10 sufferers can expect to survive disease despite shock predicted rise

Almost half of the UK population in 2020 will get cancer in their lifetime - but four in every 10 will survive the disease, the country's leading cancer charity has said.

The startling prediction from Macmillan Cancer Support came with a warning that, despite better survival rates, caring for cancer sufferers and survivors poses a “herculean challenge” for society and the NHS over the coming decades.

Macmillan's estimate is the first to take into account the UK's ageing population as well as ever-improving chances of surviving cancer.

The proportion of people who will get cancer at some stage in their life has increased by more than a third over the past 20 years, the charity said, and if current trends continue that number will rise to 47 per cent of the population in just seven years' time.

As people live longer the proportion of the population getting cancer - often later in life - has increased dramatically. Better diagnosis and treatment means that more people than ever before are surviving the disease - but living with debilitating physical and emotional after-effects.

“This poses a herculean challenge for the NHS and society,” said Ciarán Devane, Macmillan's chief executive. “The NHS will not be able to cope with the huge increase in demand for cancer services without a fundamental shift towards proper after-care, without more care delivered in the community, and without engaging cancer patients in their own health. Until then, the help and support that organisations like Macmillan provide will become even more urgent to ensure no-one faces cancer alone.”

Macmillan's estimate was based on current figures for cancer incidence and mortality rates and reflects recent growth trends in both the number of people getting cancer, and the number of sufferers surviving the disease.

In 20 years the proportion of people surviving cancer has doubled from only one in five in 1992 to more than one in three today. Earlier diagnoses and continuing advances in treatment and care mean that, by 2020, four in 10 sufferers will survive.

“That we live longer as a nation, and that we are improving cancer treatment, are things to celebrate,” said Macmillan's chief medical officer, Professor Jane Maher. “We do, however, need to add a serious note of caution: the more successful we are with treatment and cure, the more people we have living with the long-term effects of cancer and its treatment. Many patients can be left with physical health and emotional problems long after treatment has ended.”
