This was tested in people. That is the most reliable kind of research we share.
This study looked back at samples from patients. It is not a treatment you can get.
The short version
A large study looked at where colon and rectal cancer spreads, and which gene changes make spread more likely.
What was studied. Researchers studied over 7,000 colorectal cancer samples. They looked at the gene changes in each tumor. They also looked at where the cancer had spread in the body.
What they found. Spread to the brain and to the adrenal glands tended to happen late. Spread to the lung, bone, and brain often showed up together. Changes in a gene group called RAS raised the risk of spread to every site they looked at. Changes in a group called WNT seemed to lower the risk overall.
What this means, and what it doesn't
What it could mean: Gene tests on a tumor may one day help doctors guess where cancer is likely to spread. That could help them plan scans and follow-up. If you want to know more, ask your care team about tumor gene testing.
What it doesn't mean: This is not a new treatment, and it is not a cure. The team looked back at samples and records that already existed. They did not test a drug in people. Doctors are not using this to guide care yet. Much more work is needed first.
