This is one patient's story with advice for doctors, not a tested treatment.
The short version
This is the story of one patient, and doctors hope it helps them spot this problem earlier.
What was studied. Doctors described one man in his 30s. His testicular cancer had spread to his brain. A scan found a weak, bulging spot in a blood vessel at the base of his brain.
What they found. Doctors sealed off the bulging spot using tiny coils and a small mesh tube. Six days later, it bled badly again without warning. Doctors could not save him, and he died.
What this means, and what it doesn't
What it could mean: Bulging blood vessels caused by cancer are rare, but they can show up in unexpected places. The doctors suggest that people whose testicular cancer has spread to the brain get scans of their brain blood vessels early. This could help find a problem before it bleeds.
What it doesn't mean: This is a report about just one person, not a study of many people. It does not show that this treatment fails for everyone. It does not prove that early scans will prevent bleeding. It is not a new treatment and not a cure.
