How rare is cancer?
Cancer is a serious and potentially life-threatening disease, but it is not as rare as many people think. According to the World Health Organization, cancer is the second leading cause of death worldwide. In 2018, there were an estimated 18.1 million new cases of cancer and 9.6 million cancer-related deaths. While cancer is not as rare as many people believe, early detection and improved treatments have led to increasing survival rates. In the United States, five-year survival rates for all cancers combined increased from 49.3% in 1975-1977 to 69.5% in 2006-2012.
