which treatment ?

My mother has stage I nsclc, she has been offered 2 choices for treatment, surgery or sterotactic radiography- Each specialist is pushing for their own treatment- She has limited lung capacity due to emphysema and limited mobility as a result of severe spinal stenosis- I worry about her recovery after surgery- Can anyone give me some insight into what the recovery is like (surgeon will do it thru portals rather than an incision)
