If it's that low stage and they are sure they got it all, they usually don't do gene typing. Gene typing is only used to choose drugs for treatment like chemo or immunotherapy. I have seen that there is a chance of recurring of about 30% (depending on article). You will need lifelong screening but usually only the once a year they recommend for everyone now. Your doc can give you specifics on your case in particular.

I was a helicopter pilot in Nam and flew while Agent Orange was being sprayed, so my doctors think it is related.

Thank you for your response

GwenJagde, I had LC 3 times. A 10 cm tumor in right lung in 2000 at age 46, then a 2cm tumor in left lung in 2021 and then a 1.5cm tumor in right lung in 2024. I turned 70 this year.

The prembolizumab…. Is Keytruda, (immunotherapy) but that would be for his PD-L1 (22c3) protein in the Geno testing. I believe it the mutation? Hard to understand all the lingo! But he also has a a more serious one EGFR DNA-tumor. There are six meds listed for that. One being Osimertinib and that’s a pill. Hoping after his 4-6 chemotherapy treatments he can begin that. It was suggested from the Dr that took over while Larrys Dr is on vacation.
On that EGFR, looking that up it said higher percentage are non-smoking Asian women. Ok, is that because of agent orange exposure? My hubby was exposed in Vietnam.
