Hi, I had gone through your question and understand your concerns. I am afraid this is bad sign and this is commonly seen in terminal stages of lung cancer. There is no much treatment possibilities. he can do bronchoscopy and if bleeding site is clearly visualized, then hemostasis can be done, otherwise, there is remedy It may stop sponttaneously bleeding, he should just lay with elevated upper body and take antitusics. All other measuers should be discussed with his pulmologist. Hope this answers your question. If you have additional questions or follow up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health.
