Approximately 13% (or 7.5 million) of the world’s deaths are attributed to cancer every year. Despite our increasing knowledge and advancing technologies, the WHO still estimates that worldwide cancer deaths will continue to reach 12 million by the year 2030. About 72 percent of these deaths occurred in low- and middle-income countries, where stop smoking advocacy campaigns aren’t as prevalent and the medical capabilities aren’t as advanced.
Less than 25% of the world’s cancer population was genetically predisposed to cancer. Approximately 80% of cancer cases are cause by environmental factors. In other words, cancer is preventable for the vast majority of people. With the proper knowledge, vigilance, and some commitment most people can prevent cancer. Consider that one fifth of all cancers worldwide are caused by a chronic infection, for example human papillomavirus (HPV) causes cervical cancer and hepatitis B virus (HPV) causes liver cancer. Many of these infections are preventable, even curable and if treated could bring down the amount of cancer cases seen per year.
