Hello, My mom has lung cancer and is currently on  chemo shots, she is 66 and has had her fluid drained from her lungs three times. She is currently having a hard time breathing and severe back pain. What I have read online so far is that it may have spread to here bones. Is there any other possible reasons for her pain and shortness of breathe?
Howell come to ChatDoctorI really appreciate your concern for your mother if this is malignancy and developed metastasis in lung tissue then such breathing difficulty is very likely, symptoms can be treated accordingly else nothing much can be done, better to have opinion from expert oncologist, take care.
