GENEVA, Aug 31: Cancer specialists set a plan on Sunday to stem the rise in deaths from cancer by 2020 and ensure that all patients suffering in the late stages of the disease can access painkillers.

The road map laid down by 63 experts and policy-makers includes more screening and early detection programmes, especially in poor countries where treatment can be hard to come by.

Tobacco and alcohol consumption as well as obesity levels must be curbed for cancer rates to drop, according to the panel.

Its declaration was presented at the end of a four-day World Cancer Congress hosted by the International Union against Cancer (IUCC).

Some 25 million people worldwide live with various forms of cancer and 7.9 million died of it last year.

“We know that one-third of the cancer burden could be cured if there were early detection and proper access to medical help,” Mary Robinson, who chaired the panel, told reporters.

Another third of cases could be prevented through control of tobacco, pollution and other hazards, according to Robinson, a former president of Ireland and United Nations High Commissioner for Human Rights.

Survival rates have improved in rich countries as cancers are detected early and treated.

But lifestyle changes means cancer is affecting more people and claiming more lives in the developing world, which accounts for three out of four global deaths, according to the IUCC.— Reuters
