Cheery, the actual SBRT is non-invasive. It's just a radiation beam, you can't see or feel it. Other things they do for liver, like ablation, need open access to the liver and they use probes to burn away tumor, etc. There are side effects to SBRT though - it can cause gastro problems, chest wall pain, fatique.
What I had wasn't a probe, it was a marker. They put them around the tumor so that it can be tracked through your breathing cycle. It was invasive to put those markers in, but only minimally, not like a surgical procedure (which I have also done).
Now I don't understand your sentence - you said you were going to have SBRT if your scans were clear? My understanding is they are destroying tumor tissue, they won't do it on regular tissue, which is what will happen if you get clean scans. They need to be able to see tumor to do this procedure. They do it on people like me, who have only been partially successful with chemos, or people early in mets who only have a met or two that they can get to. They like the tumor to be around 3 cm; that's the size they say they can destroy easily. So I am confused by what you just said - maybe you are having something different? How would they do SBRT with no tumor?
