Cancer Statistics: Global and National
Cancer is the second leading cause of death throughout the world, second only to cardiovascular disease. Globally, in 2015, there were 17.5 million cancer cases and 8.7 million deaths. From 2005 to 2015, the number of cancer cases rose by 33%. The Global Burden of Disease Cancer Collaboration attributed this increase to population aging 16%, population growth 13%, and changes in age-specific rates 4%. In the United States, the American Cancer Society predicts 1,688,780 new cases of cancer with 600,920 Americans expected to die of cancer in 2017. The identification of modifiable risk factors is of prime importance in the effort to decrease both cancer-related mortality and disability. The prime risk factors identified are exposure to tobacco, high body mass index, lack of physical activity, low fruit and vegetable intake, alcohol use, exposure to ultraviolet radiation, and chronic viral infection. This literature review looks at the increasing prevalence of cancer throughout the world and some of the modifiable risk factors for cancer prevention.
