This was tested in people. That is the most reliable kind of research we share.
This study counts cases and plans ahead. It does not test any treatment.
The short version
Death rates are slowly falling, but far more people will face this cancer by 2050.
What was studied. Researchers pooled world cancer records, health system data, and population counts. They looked at trends from 1990 to 2023, then estimated what the numbers may look like in 2050.
What they found. In 2022 there were 321,731 new cases and 248,500 deaths worldwide. The rate of new cases stayed about the same from 1990 to 2023, while the death rate dropped a little. By 2050, the study expects about 605,000 new cases and about 351,000 deaths each year. Higher income countries recorded more cases and more deaths, which may partly reflect better testing and more doctors.
What this means, and what it doesn't
What it could mean: More families around the world will face this cancer as people live longer. Health systems need to plan now for the staff and care these patients need. Where you live still shapes how likely your tumor is to be found and counted.
What it doesn't mean: This is not a new treatment, and it is not a cure. No drug, test, or therapy was studied here. The work only counts cases and deaths and estimates future totals. The 2050 numbers are rough planning guesses, and the real numbers could be much higher or lower. A bigger world total does not mean your own risk is going up.
