Had colon and 108 lymph nodes removed, followed by chemotherapy. Last chemo was in Nov 2021. I have one small unidentifiable spot which during the last two scans which was decreasing in size, and the last scan was increasing again. The the scan interval was changed from 6 months to 4. Next scan is late this month. Yes, I still have the port in and they flush it monthly. That port removal topic will come up at my next appointment with the oncologist.
