My friend is an advanced  lung cancer patient and have gone through series of chemotherapy. I have now started coughing blood for the last six months. I am on gestin B 260 mg  tablets and acitrome alternating between  4 mg, 3 mg, 2 and 1 mg, erlotinib 150 mg. What could be the cause of the coughing and the blood that comes with it?
Why is the patient on acetone (warfarin)? Is the patients INR being monitored. If the INR is beyond the target INR, it can cause bleeding. Blood in cough (hemoptysis) can be due to advanced lung cancer itself with an endobronchial growth bleeding which can be triggered or further complicated by acetone. The offending Chat Doctor. Please discuss it with your oncologist.
