My husband had lung cancer which took 2 lobes of his right lung. Got all the cancer with no chemo. Now he has severe (stage 4) enphazema and fibrosis in the other lung. He was fading before my eyes. He has been on prednisone but completes the prescription in about a week. He was so bad off before that I am wondering what we can expect now. What will he go through? What can we do?
