I became sensitive to the iodine contrast with the CTscan over time,so now I can only have a PET Scan and/ or a full body bone scan or a MRI. I'm stage4 MBC with tumor markers numbers that get elevated when there's cancer growth going on. As of lately my oncologist has me getting PET scans every 2 months. I'm taking a fairly new treatment and I'm being monitored very closely. So every 2 or 3 months I get scans. I've been having them since my diagnosis in 2021. I can't tolerate a MRI scan,so I travel out of town to get an Open MRI. It's not as claustrophobic as the Tube.

In my experience the answer is no. I didn't start getting regular PET scans until after being diagnosed with breast cancer first and followed by endometrial cancer. When my endometrial cancer returned for the first time as a lump right under the incision scar from my hysterectomy I demanded a PET scan to see if the cancer had spread anywhere else. Ever since then I have been getting a PET scan every 3 months. My endometrial cancer, which returned 2 more times after that, and my 2nd round of breast cancer were all caught by PET scans.

Typically a PET scan will be done if there is reason to believe your cancer has returned locally or has metastacized to your bones or organs like you liver, lungs, brain, etc.
