Increase in Global Cancer Incidence, Drop in Death Rates
From 2006 and 2016, smallest increase seen in high Sociodemographic Index countries.
HealthDay News — Worldwide, cancer cases increased by 28% from 2006 to 2016, according to a study published online June 2 in JAMA Oncology.
Christina Fitzmaurice, MD, MPH, from the University of Washington in Seattle, and colleagues examined the burden for 29 cancer groups over time. The Global Burden of Disease study estimation methods were used to assess cancer incidence, mortality, years lived with disability, years of life lost, and disability-adjusted life years (DALYs) for 195 countries and territories.
The researchers found that there were 17.2 million cancer cases worldwide and 8.9 million deaths in 2016. Between 2006 and 2016, there was a 28% increase in cancer cases. High Sociodemographic Index countries had the smallest increase. Population aging, population growth, and changes in age-specific rates contributed 17, 12, and −1% to this change globally, respectively. For men, the most common incident cancer globally was prostate cancer, while the leading cause of cancer deaths and DALYs was tracheal, bronchus, and lung cancer. For women, breast cancer was the most common incident cancer and the leading cause of cancer death and DALYs. The average annual age-standardized incidence rates for all cancers combined increased between 2006 and 2016 for 130 of 195 countries or territories, while the average annual age-standardized death rates decreased in 143 countries or territories.
"Large disparities exist between countries in cancer incidence, deaths, and associated disability," the authors write.
