Have you completed a lung function test and an echocardiogram stress test yet? If they are pushing you to choose, they should have ordered these for you, so that you can be sure that surgery is even an option. One of the reasons my Aunt had SBRT was because her heart could not have handled the surgery on her lungs. I see you “name” is Mayocid1 but I’m assuming you are not being seen by Mayo Clinic?
