Hi my dad was diagnosed 2 year ago with advanced prostate cancer which had spread to spine , ribs, and pelvis then had a repeat scan a few weeks back with showed lesions in the right lung and now has spread to his lymph node in groin. Now he has started to cough up blood quite a bit he was admitted to hospital for one night which they did a chest X-ray that showed fluid on his lung then discharged him with antibiotics since been home he has basically been coughing up clots/tissue on a daily basis has any one experienced this?

thank you for taking time to read / reply
