My 80 year old mother was experiencing a chronic cough that has gotten worse and is worse when she lies down at night. She also has shortness of breath, chest pain and back pain. All symptoms are getting progressively worse. Instead of her primary starting a workup other than general lab work, he has chosen to send her directly to a cardiothoracic surgeon without doing even a chest X-ray. She is relatively healthy, has hypertension and type 2 diabetes and is overweight. Any reason why her doc would choose this path. She is a non-smoker but grew up in a bar and around passive smoke. We are really concerned that he is looking for lung cancer?be
