<s>[INST] My mother is 60 years old (diagnosed with leukemia) and often she has breathing problems especially when she walks she would be gasping for breath afterwards. At nights she can t sleep because of this issue. She was prescribed Aeroflux to use for one week but the problem is still there [/INST] You did not mention the type of leukemia: acute or chronic, lymphocytes or myeloid. From the description in your query it seems she is not on any active oncological treatment. Breathlessness (dyspnea) can be due to many causes in a patient with leukemia: low hemoglobin, respiratory infection, embolism, pleural effusion etc. You can discuss it with your oncologist. I would be in a position to guide you better if you improve upon the details in your question. </s>
