Hello, this is Dr K.. Answers are not medical advice and do not constitute a doctor/patient relationship. I look forward to helping you today.
I am very sorry for your Dads diagnosis.
The pet scan is not 100 percent accurate and if the cancer is in the lymph nodes and brochial tubes, it was already there 5 weeks ago.
Lung cancer can be staged clinically for example by pet scan.
When many patients get to surgery, the actual staging by pathologic staging, is more advanced and much worse.
This is true even when there is not a 5 week delay.
From what you describe this is a stage 3 b lung cancer and surgery is not the treatment. It cannot cure the cancer. Chemo and radiation is the treatment.
Im very sorry.
For patients with this type of advanced lung cancer in whom surgery is not an option only about a quarter live three years. with radiation and chemotherapy the average survival is about a year. Im sorry, Its not good news.
