This was tested in people. That is the most reliable kind of research we share.
This is a report on two patients, not a treatment being tested.
The short version
Doctors describe two partners who each developed a brain tumor about 20 months apart, and no shared cause was found.
What was studied. This is a report on two adults in northern Italy who were partners. They shared a home since 2018 and a workplace since 2016. Doctors described each person's tumor in detail and asked about things they may have been exposed to.
What they found. Both people had glioblastoma: The fastest-growing type of glioma (grade 4). Treatment usually starts soon after diagnosis: surgery first, then radiation and chemotherapy. See the glossary, a grade 4 brain tumor. One was a 47-year-old woman. The other was a 51-year-old man. Their tumors were about 20 months apart. Gene testing showed the two tumors were not the same in their makeup. The woman's tumor came back and later spread, and she died.
What this means, and what it doesn't
What it could mean: Doctors looked for a shared cause and did not find one. Living or working in the same place was not shown to cause either tumor. Many things were never measured, like radon, indoor air, and water. So the doctors could not rule those out either. For most patients, this changes nothing about their own care.
What it doesn't mean: This does not mean brain tumors spread from person to person. It does not mean a home or office caused these tumors. This is a report on two people, not a study that can prove a cause. It does not test any treatment. It is not a cure and it is not a step toward one.
