I am having a left upper lobectomy for stage 1. What can I expect?

Hopefully VATS. Vats or video-assisted thoracic surgery should be offered to nearly all patients with stage i lung cancer, as it leads to less pain faster recovery. Ask your surgeon for a minimally invasive lobectomy!
Good prognosis. Prognosis in lung cancer depends on a variety of factors. The overall 5-year survival rate for people with stage 1 lung cancer is 60 to 80%. Recent studies suggest that finding lung cancer early through screening may result in 5-year survival rates of 90% or more.
Robotic or VATS. Hopefully, you will undergo minimally invasive thoracic surgery (mits) by a well trained thoracic surgeon. Early stage lung cancer patients that are appropriate can usually undergo robotic or vats resection. These techniques allow faster recovery and avoid rib fracture and rib spreading.
