Do cancers show up on CT scans?
CT scans can show a tumor’s shape, size, and location. They can even show the blood vessels that feed the tumor – all in a non-invasive setting. By comparing CT scans done over time, doctors can see how a tumor is responding to treatment or find out if the cancer has come back after treatment.
What cancers does a CT scan not detect?
