Unfortunately, I know so much about this silent killer  because I lost my wife of 35 years on April 9 of this year. My wife, Nancy, was  diagnosed stage 4 lung cancer in 2012.
This diagnosis came four months after  receiving a clean bill of health following her annual physical, there were no  symptoms of the cancer. The only way we were able to find out she had lung  cancer was because she had a small bump in her neck. The bump was a lymph node  that was infected with cancer. Had Nancy done a lung x-ray as part of her  annual physical, the cancer may have been discovered while still in the lung.  Once it leaves the lung it is most likely a terminal illness it can be cured if  caught before leaving the lungs.
Nancy fought a courageous battle for over six  years, overcoming, chemo pills, radiation, three collapsed lungs, brain surgery and  full brain radiation, yet when you met her you would never know she was sick,  she was always cheerful and smiling, never gave into the cancer. She passed  during a medical procedure while under anesthesia, I thank god that she passed  peacefully. Only 5% of lung cancer patients diagnosed stage 4 survive five years or  longer. She was a fighter.
My three sons and I miss her dearly. But we have an  opportunity to carry on her legacy and turn a dark story into a bright story.  Screening is critical, whether you are a smoker or not. The statistics are  staggering, I can go on and on. Educate yourself and discuss screening with  your doctor just as you would with prostate, breast or colon cancer. Remember, 1/3  of lung cancer patients never smoked, that's 50k people per year, not to  mention all of those living with lung cancer.
