What Are the Symptoms and Stages of Progress of Lung Cancer?

I can only speak from experience. I thought I had bronchitis, went in for antibiotics, had an xray, suspicious shadow found.. follow up CT scan showed a strong possibility of lung cancer so went for biopsy. Stage iv non small lung cancer was found. Other than that, I had no other symptoms. I had extensive chemo, which had no wide effects on my tumors but have helped keep me stable for the past 3 years. Progression I was told would be distant metastasis eventually to other organs. Prognosis for me was less than a year of life with treatment, its now nearly three years with no progression. Its a daily fight winning one battle at a time, weather I win the war tho is a whole different story and one I am never too sure about. Time frames are different for everyone. I live for the future, and not worry about today. Right now, each day is a gift.
