I'm feeling worried as I had colon cancer last year which was removed with curative LAR. I had all clear markers on my histology report. On my yearly CT surveillance a 7mm nodule was picked up on my lung as being suspicious. I was sent for a PET Scan which has now added suspicious activity on my liver as well, I am now having an MRI on Sunday to hopefully get more information on this. Would cancer not be obvious on the PET Scan?
