Cancer is a leading cause of death worldwide, accounting for 8.2 million deaths in 2012.
Lung, stomach, liver, colon and breast cancer cause the most cancer deaths each year.
The most frequent types of cancer differ between men and women.
About 30% of cancer deaths are due to the five leading behavioral and dietary risks: high body mass index, low fruit and vegetable intake, lack of physical activity, tobacco use, alcohol use.
Tobacco use is the most important risk factor for cancer causing 22% of global cancer deaths and 71% of global lung cancer deaths.
Cancer causing viral infections such as HBV/HCV and HPV are responsible for up to 20% of cancer deaths in low- and middle-income countries.
About 70% of all cancer deaths in 2008 occurred in low- and middle-income countries.
Deaths from cancer worldwide are projected to continue rising, with an estimated 13.1 million deaths in 2030.
