Good morning- I have stage 4A lung cancer. I am 22+ years strong. But I always wonder how my immune system will hold up under pressure. Daily I have been bombarded by everything out in the universe and I have been lucky so far. I've had a few cases of bronchitis and only one case of pneumonia. My body is used to fighting these elements. But COVID-19 is new and there is still little known about how it works. The coronavirus is testing our immune system. It is pushing hard and as we know for certain groups it is deadly. But how does our immune system work during this a pandemic? As the immune system works to fight it off I wonder if it has the strength to prevail as a woman of mature age before it completely destroys what little lung I have left.
