I read a post somewhere about a tumor on the diaphragm and having a dry cough and coughing up bloody sputum but cannot find it. If you wrote about it, could you please answer a question on two? I have unexpectedly coughed up some sputum a couple of times in the last month, although it wasn't bloody. I have also felt a tightness in my diaphragm area when jogging, and my CA125 has gone from 13 to 56. How did the doctor find it? Was a CT scan necessary or was it palpable? Was the removal basically uneventful and easy? I'm having my blood rechecked in a couple of weeks and will definitely mention this to my doctor. Thanks for any help!
