This looks across many earlier studies rather than running a new one.
This was only done on cells in dishes, not in people.
The short version
Scientists played sound to cancer cells in dishes, and the results are early and unclear.
What was studied. This paper reviews lab studies of audible sound, music, and sound waves aimed at cancer cells. The cells came from breast, stomach, prostate, colon, ovarian, nerve, and glioblastoma: A glioma that is given grade 4. Grade 4 is the highest grade there is. The tumor grows fast. Treatment usually starts soon after it is found. It often means surgery, and then radiation and chemotherapy. See the glossary brain tumor models.
What they found. Some studies saw changes in how cancer cells lived, grew, and moved. The effects differed a lot by cell type and by how the sound was played. The authors say no study proved that sound caused these changes. They also found no proof that sound affects only cancer cells.
What this means, and what it doesn't
What it could mean: Music therapy is already part of cancer care. It is used to ease anxiety, pain, and distress, and that help is real. But this review does not show that sound or music can act on a tumor itself. Nothing here changes your treatment.
What it doesn't mean: This does not mean sound or music can treat a brain tumor. The work was done on cells in dishes, not in people. The authors call the findings early and uneven. Much of the thinking comes from ultrasound research, which does not apply to music you can hear. This is not a cure, and it is a long way from everyday care.
