Health experts are calling for action to expand cancer care and control in the developing world. A paper published by the medical journal Lancet says cancer was once thought of mostly as a problem in the developed world. But it says cancer is now a leading cause of death and disability in poor countries.

Experts from Harvard University and other organizations urge the international community to fight cancer aggressively. They say it should be fought the way HIV/AIDS has been fought in Africa.

Cancer kills more than seven and a half million people a year worldwide. The experts say almost two-thirds are in low-income and middle-income countries.
