I am concerned about my boss. She has some good days but other days she seems very confused with simple tasks. She gets hoarse and coughs quite often. On these days she is also extremely tired and pale. She has no energy at all. She has had an endoscopy and a colonoscopy recently but those tests were fine. I have asked her to have some lung x rays. My neighbor died from lung cancer recently and he had some of these same symptoms. She says that she is scared to ask for the xrays because her brother died from lung cancer as well. What is your opinion on this?
