Today morning I woke up and cleared the cough. I saw fresh red blood on it. I coughed 4-6 times and still the blood was there along with cough. This is the first time I see such blood in my cough. Day before today, when I used to cough, I used to see normal (a bit of gray colour sometime) cough every morning. I googled with these symptoms, I am terrified that if it's the symptom of any major disease like TB / Cancer etc. I am 39 years old Male. Please suggest/advice what should I do further? Thank You.
