My mother, 64, is to see a DR on Wed, but I am wondering what the possiblities could be. She lives in another state, & on the phone not too long ago she asked what a panic attack felt like, I told her of mine & she said she thought she was having them bc she was having shortness of breath. She told my sister she was going to have a mamogram(wed) because she was feeling pains in her breasts, no lumps. I think she tried to write off the breast pains & breathing problems as a mild panic attack, but I think she is sure that is not what it is. She lives with a smoker, has all of her life and she works in a bar around smokers. I am wondering if the DR’s are looking for lung cancer. What other things could show these symptoms?
