Scientists have long known that cancer cases among adults younger than 50 have been on the rise in many parts of the world since the 1990s. But a new study suggests that certain types of cancer – breast, tracheal, bronchus and lung, stomach and colorectal – have caused the most disease and death in this younger age group.
Uhhh, yeah. Different kinds of cancer are different, in almost every way possible, except for the fact that they are all cancers.
The phrasing to me makes it sound like triage medicine - “since younger people have it we have to pick whose cancer we care about”
