Megadeth leader Dave Mustaine revealed in the concert held at the SSE Arena in London, UK in January 31 that he is 100% free of cancer. Since last month the band is playing live again. Dave Mustaine said: "About a year ago, we were working on our new album back in Franklin, TN, and I started to feel some pain here *points at throat*, so I went to the doctor and he said, 'Dave, you have cancer.' "And I went, 'Fuck!... I have cancer...' I was so shocked. At first, I thought, you know, 'Am I afraid?'; and I said, 'No, I'm fucking pissed.' "And we stopped the record, we stopped everything, I went into treatment for cancer. It was 51 radiation treatments and nine chemo treatments. "And when it was all said and done, every day I would think, 'I can't face not playing again; I can't face not playing again.' "So I would pray - I know a lot of you guys know that I pray, I say that in 'Peace Sells' [refering to the 'What do you mean I don't believe in God? I talk to him every day' line in the 1986 song]; I pray every day, I say that in the song, I've been saying it since the second record. "But I thought about you guys every day too, and I thought about my family, I got this power from you guys and I just kept thinking about it... "And on October 16, I went to go see the doctor and he said, 'You're 100% free of cancer.'"
