I was diagnosed as stage IV lung cancer in March 2012. I had chemotherapy, upper left lobectomy (in October) and radiation on my femur. So far so good. My concern now is catching the common cold and triggering complications from it. I take all the normal precautions but am a mother of three teens and a college son who all live at home. Any thoughts? Trusting in health may come in small doses for a while I think.
