Understanding PET/CT and Cancer
PET/CT is particularly useful in figuring out how well cancers are responding to treatment, determining if someone is cancer-free, and identifying whether cancer has returned and where it’s located.
Staging Cancer
PET/CT is excellent at figuring out the full scope of a disease, particularly for certain types of cancer. By confirming if cancer has spread, doctors and patients can make more informed decisions about the best course of action.
Spotting Recurrences
Right now, PET/CT is considered the most accurate way to tell the difference between a returning tumor, damage from radiation, or changes after surgery. Knowing this helps doctors create a more tailored treatment plan for the patient.
Measuring Chemotherapy Success
Doctors compare how active a tumor is on PET/CT scans taken before and after chemotherapy. If the PET/CT scan shows a positive response, it’s often an earlier sign of the tumor shrinking compared to other tests.
Early Detection
PET/CT scans show what’s happening at a biochemical level, so they can accurately determine if a tumor is harmless or dangerous. This might help people avoid a surgical biopsy when the PET/CT scan comes back negative. On the flip side, since a PET/CT scan looks at the whole body, finding cancer spread in other areas can change the treatment plan from surgery to chemotherapy in some cases.
