Cancer in developing countries: The next most preventable pandemic. The global problem of cancer

Cancer is a global problem that accounts for almost 13% of deaths worldwide, a number similar to the 7 million deaths each year from HIV/AIDS, TB and malaria combined According to Globocan it is estimated that by 2020, there will be between 15 and 17 million new cases of cancer every year, 60% of which will be in developing countries. Moreover, the survival rates in these regions are often half those of developed countries. However, cancer is potentially the most preventable disease; with current resources, one-third of tumors could be preventable, and another one-third of newly diagnosed cancer patients could experience increased survival or early-stage detection. There have been proposed several strategies and programs to ameliorate cancer prevention and treatment in less developed countries. If all these proposed strategies are taken into consideration, worldwide cancer care, control and survival in low-income countries may improve in the years to come.
