The doctor said he didn’t even feel that follow up was needed at all based on all other results. The only reason he scheduled the 6 months CT was because of the “possible 1 mm size increase” on last CT, but that was not confirmed by PET scan, which came back as same size of 8 mm. Based on nodule presentation, the doctor thinks mild speculation was caused by severe Covid pneumonia she had back in 2021 that stretched the tissue slightly. So it has been stable in size for the past 3 years and he feels like frequent CT radiation exposure is not necessary in the case.
