It has long been understood that cancer risks and mortality rates increase as individuals grow older, thanks to the natural mechanisms of biology and aging. At the same time, increasing life expectancy has created a new, much older age bracket in the population. As a result, it becomes increasingly worth asking: What are the health risks and trends for this new group of the “oldest old,” and how can studies on this group help us better understand the links between aging and chronic disease? This study takes these questions into consideration and detects surprising drops in cancer mortality rates for the “oldest old” as compared to the “old.” Other surprising age and gender-specific peaks and drops in cancer mortality rates are also detected and discussed.
Trends in countries where cancer mortality rates eventually declined with age.
