Hi Colleen , I just read your post and I can relate to it. My brother also has been diagnosed with cancer. He is my only sibling and we loss our parents a few years ago. He has stage 4 inoperable lung cancer plus his lungs keep filling up with fluid. It’s so hard to see your brother suffer to breathe even though he is on oxygen. I have to put my faith in God. I am praying for Jesus to do a mighty miracle. I will be praying for your brother along with mine. I love him so much. I just can’t lose him!
