Hi, My dad who is 93 yrs old has had problems with fluid on his lung. He has had his flui drained, then still had some left, then had it suctioned off and cautuerized. He was coughing alot throug out both procedures and had the fluid biopsied. The biopsy came back inconclusive, suggesting lung cancer, but, possibly pneumonia or some type of infection. He is still coughing up phlem, sometimes greenish, somtimes clear. His nose runs alot as well. He is currently seeing a Naturopathic doctor for intravenous therapy, a mix of vitamin B12 and other vitamins to help his immune system. The coughing isn't as often, comes and goes, and still with some phlem. He does have some tenderness on the same side that the lung is that he had problems with, and we found out today, that his liver is showing some abnormal function. Could this be related to some type of infection (pneumonia, that hasn;t cleared up), or do you think his liver issue is related to the lung problem ? His urine sample on Monday of this week (June 3) was normal, however today it wasn't. Is this cause for concern?
