For eight years megastar, Amitabh Bachchan did not know he was suffering from Tuberculosis and said that he does not mind calling himself a tuberculosis survivor. Amitabh was at NDTV's Swasth India launch and was speaking to doctor Harsh Vardhan urging him to spread awareness about regular check-ups to facilitate early diagnosis.

"I keep quoting my personal example all the time and try and propagate the idea of getting yourself detected and I don't mind saying this publicly I am a tuberculosis survivor, Hepatitis B survivor... Bad blood infusion went in and 75 percent of my liver is gone but because I was able to detect it even after a period of 20 years when 75 percent of my liver is gone. I am still surviving on 25 percent," said Big B.
