Lung filled with fluid.

Mine did not fill up until after radiation.  I had radiation last June,And Afterwards it started to fill.  By November It was in such bad shape that I was having a horrible time breathing Because there was so much fluid.  I had a large pleural effusion That was drained in the office. Yes, it was painful, oBut seemed to do the trick. Unfortunately upon analysis of the fluid, they discovered that it was full of cancer in my pleural area.  That means that my lung cancer had metastasized from both lungs into the pleural area of 1 of my lungs.  It just so happens that it was the long that was radiated.  I ended up in the hospital Between Christmas and new year's Because I could not breathe anymore From that area.  Since it had filled up extremely rapidly And Look like it was going to continue to fill up repeatedly until the cancer in the pleural area was killed I have had a pleurx drain tube inserted into my chest.  Right now we drain the fluid from the pleural area every week here at home.  I am now back in chemo like I was 2 years ago, But a completely different regiment and it's making me sick as a dog.  Apparently, pleural effusions are not uncommon with lung cancer.  They can usually be drained easily in an office, what is unusual is how fast mine comes back, Necessitating continuous drainage.  I had two options. The drain permanently put in my chest, or going into the doctor's office once a week and having them do it. I live way out in the country And Getting a weekly appointment for drainage Is very Difficult.  Sometimes, or pleural effusion will correct itself.  If your father's effusion does not do that, then ask how you can get it drained.  Most likely,They can do it right there .
