My sister just had her 1st cat scan and MRI following her completed round of chemo. tumor shrunk a little, no mets to liver . she was recently tapped for 6 liters of fluid from abdomen. Her legs and feet have been getting increasingly more edematous where she can hardly lift them off the ground. they have just added another diuretic but so far fluid is not moving from her legs or feet if anything it has gotton worse . she was just placed on a 3rd diuretic but nothing yet? I want to know what is causing the edema and why aren't the diuretics working/ If they don't work what can be done for her legs?
