I'm really worried about my mom's recent X-ray results. She's diabetic and had a heart bypass back in 2012. The X-ray mentioned something about fibrosis in both upper lobes, and I've been reading up on fibrosis, especially pulmonary fibrosis. It seems so scary since it's apparently incurable and can be fatal. I really dont want to lose her. Can you tell me more about what this means and what we should do next?
