<p>Breast cancer metastasis to pleural fluid of lung.</p><p>I am 71 and on my 3rd event with left side breast cancer. The first time was in 1999, then again in 2009, and now in 2023. The first time I had a simple mastectomy, no lymph nodes removed and no other conventional treatment. The second time the cancer spread to the skin of the chest and axilla and 2 out of 8 lymph nodes. I had surgery, Arimidex, and radiation to the left side chest, axilla, and supraclavicular lymph nodes. No chemotherapy. I stopped the Arimidex after 8 months. Now, 14 years later, the breast cancer is in the pleural fluid of the right lung. I recently had an in-dwelling pleural catheter put in to be able to drain the fluid at home. Very unpleasant. I would like to connect with others who have this type of catheter due to breast cancer metastasis. I hope there are others on this website with a similar experience.</p>
