My sister has been fighting bile duct cancer for 3+ years. She has been retaining fluid in her abdomen, which I believe is called ascites. She has been to the doctor and has had her abdomen drained twice, 5.1 liters and 6 liters respectively. She has lost a lot of weight, is fatigued, and seems very uncomfortable. She has recently had a home health nurse drain 1.0 liter (twice) from a drain in her abdomen and is on schedule to have it drained every other day. I m sure she is nearing the end, and was wondering how much longer she may have considering the fluid can not be drained fast enough. Thank you
