This was tested in people. That is the most reliable kind of research we share.
This is a report about one patient, not a test of a new treatment.
The short version
A man's back pain and weak legs came from lung cancer that had spread.
What was studied. Doctors wrote up one patient, a 69-year-old man, and reviewed past reports. He had 4 months of low back pain, numb legs, and trouble walking.
What they found. A first spine scan done without dye showed small spots near the lower spinal nerves. Those spots were missed, and he was treated for a disc problem for 3 months with no help. Later scans with dye showed cancer spread along the lining of his brain and spine. Chest scans found a lung tumor, and tests confirmed lung cancer.
What this means, and what it doesn't
What it could mean: Back pain and leg weakness can have many causes. In an older person, cancer spread to the lining of the brain and spine is one of them. A scan with dye can show this when a plain scan does not. If weakness or bladder problems get worse fast, tell your doctor right away.
What it doesn't mean: This is a report about one patient, not a study of a new treatment. It does not test a new drug, and it is not a cure. It also does not mean back pain is usually cancer. Most back pain has other causes. Any choice about scans or care is for your own doctor to make with you.
