About a million people aged below 50 die of cancer annually, a study says, projecting another 21 percent rise by 2030.
I mean sure. But the data is likely comparative and can be looked at just within countries that have been getting autopsies since the 90s.
Even in the US, autopsies are not always performed. Ima quote WebMD because Iβm bone idle:
Although laws vary, nearly all states call for an autopsy when someone dies in a suspicious, unusual, or unnatural way.
Many states have one done when a person dies without a doctor present. Twenty-seven states require it if the cause of death is suspected to be from a public health threat, such as a fast-spreading disease or tainted food.
According to a 2012 DOJ report, only 8.5% of US deaths result in autopsy.
