Sorry to be so blunt. Why would you push for surgery or a second nodule? If T's got a long nodule which turns on to be metastatic spread or 'seeding' I can almost guarantee that she will not be offered surgery. It would be pointless. It would confirm her body is full of metastatic disease slowly popping up. Systemic treatment would be used, ie chemotherapy.I sincerely hope that you are correct. However, she already had one cancer metastasis in her lungs, and she didn't have chemotherapy after that. She likely has cancer cells all over her body and in her lymphatic system, but they are too small to be detected at this moment. If it is true that she has very small cancer cells still in her body, then her body is weakening with time, and this next nodule might not take as long to grow as the previous one.
I believe it is likely downhill from here, unfortunately. In her place, I would push to have surgery to remove that nodule before it has a chance to grow bigger. If it is just a benign nodule, the surgery should be much less complicated than her previous lung surgery as resection might not be needed. If the nodule isn't benign, then margins would have to be taken again and a second resection done. I would not do well with a 'watch-and-wait' approach on this SECOND lung nodule seeing as how the previous lung nodule was cancerous!
Tiffany has money. She could very well find a lung surgeon ready, willing, and able to remove that nodule as soon as possible!! She shouldn't gamble with her life 'watching and waiting' anymore.
My late husband had a 'lung nodule' pop up in his right upper lobe in his lung. It was only small measuring 5mm and the oncologist said it had also been present on the previous scan but it wasn't reported. The radiographer 'marked it' but didn't report on it. When it showed on the second scan 3 months on, then the radiographer was suspicious and reported it. People would be surprised at how many times patients find out they have a nodule or even a large tumour, and are told it was also on previous scans but not reported on. I actually believe Tiffanys oncologist may need to contact the radiographer to ask if there is a change in size and how longs its been observed for on scans. If the radiographer felt it was suspicious then there would be no major rush to do anything. Observing would be sufficient.
The reason oncologists don't do second, third and fourth resections is because surgery isn't enough. Systemic treatment is needed.
