- Tested in people
This was tested in people. That is the most reliable kind of research we share.
This looked at past death records in people, not at any new treatment.
The short version
These deaths dropped for years, but they have gone back up since the mid-2010s.
What was studied. Researchers looked at US death records from 1999 through 2024. They counted deaths in adults age 25 and older where cancer had spread to the brain or its lining.
What they found. There were 447,724 of these deaths in all. The death rate fell from 9.65 per 100,000 people in 1999 to 8.01 in 2024. It dropped fast at first, then started to climb again after the mid-2010s.
What this means, and what it doesn't
What it could mean: This study does not change your care. It shows who is hit hardest. Deaths were highest in adults 65 and older, in men, and in areas outside big cities. Most of these deaths, 42.85%, happened at the person's home. The authors say the best way to lower these deaths is to control the first cancer better, and to make brain care easier to reach for everyone.
What it doesn't mean: This is not a new treatment, and it is not a cure. No drug was tested here. It is a count of past death records, nothing more. It cannot tell you what will happen to any one person. It does not change what your doctor can offer you today.
