Although the disease has a reputation of being a condition that afflicts the rich,it is increasingly affecting the world’s poor. New research published this past February by the American Cancer Society(ACS) shows that two-thirds of the 7.6 million cancer deaths recorded globally in 2008 occurred in low-income states. This number is expected to double by 2030. Cancer patterns are different in Africa than elsewhere.Though shifts in diet and exercise habits are contributing to the continent’s cancer rates,not every factor parrots the disease’s trends展开更多
