I'd really appreciate your thoughts. So my mom is roughly 3.5 years out after a wedge resection to her R middle lobe for a 1cm nodule that was negative on PET. One lymph node was additionally found positive upon resection and it was typed adenocarcinoma (KRAS mutation). She had follow up concurrent radiation and chemo (which were ROUGH for her), but since healing and a bout of radiation pneumonitis(sp?), things had been good since.
Then just this past August she had one her follow up CTs and an area looked a little questionable in the lower R lobe. They decided to wait a couple months (she was out-of-town) and she had a PET-CT to evaluate yesterday. The lung area on PET did not light up and doc felt confident it is not an issue at this time. (Makes me a little nervous considering her original positive mass never light up either...but I gotta have some faith here).
However, she had a spot in her spine around L5 (or L6?) that did light up on the PET (but nothing really showed on the CT in that area). The same spot had also lit up a mild amount on her PET last Jan., but this time it had more uptake (I don't know the uptake numbers). She's 72 and she has pretty bad kyphosis(sp?) and in general, far from fantastic posture. She complains of no pain in the spine, just some getting "older" aches and pains now and then. She's not a super active lady. Doc doesn't think this is cancer, but also mentioned it doesn't appear in the area where an arthritic change normally takes place (something about this uptake is located more in the middle rather than on the outside on L5 or L6 area...I can't recall exactly what was said). She is having an MRI done today of the spine.
If not cancer, what the heck else could this be? Also, thoughts on MRIs and detecting bone mets in the spine vs. using PET/CT? Feel a bit nervous and terrified (& doesn't help that I'm almost 8 months pregnant with my first kiddo...pregnancy hormones & cancer stuff togeth
