My uncle has recently been in hospital twice over the last month due to chest infections and low sodium. He has been discharged from the hospital today, however we received a call to say he either has severe pneumonia or lung cancer, due to them finding fluid on his lungs from a ct scan. He is booked in on the 15th February for a biopsy. I'm really worried that he may have lung cancer and being sent home and having to wait for the biopsy will just allow his possible cancer to get worse. He is my world and like a dad figure to me. I can't discuss my concerns with my family and make them more worried. I've done so much research and I don't know what to do or think.
