What is Dave Mustaine diagnosed with?

Throat cancer diagnosis in 2019

On June 17, 2019, Mustaine announced he had been diagnosed with throat cancer (Wikipedia). Later reporting specified it was squamous cell carcinoma at the back of his tongue (Blabbermouth (metal news outlet)). Doctors reportedly gave him a 90 percent chance of beating the illness.

The upshot

Mustaine faced a cancer that threatened both his career and his life — but he responded with the same stubbornness that kept Megadeth alive for four decades.

Treatment and recovery

  • Underwent 51 radiation treatments and nine chemotherapy sessions (Blabbermouth)
  • Returned to the stage in early 2020 before the pandemic halted touring
  • Announced he was cancer-free on January 31, 2020, during a Megadeth concert (Wikipedia)

The implication: Mustaine’s recovery gave him a new lease on a career that already seemed improbable.

Why did Metallica cut Dave Mustaine?

The 1983 firing

Mustaine was fired from Metallica in 1983, just before the band recorded Kill ‘Em All. He was replaced by Kirk Hammett (Wikipedia). The reasons cited were excessive drinking and aggressive behavior.

Reasons: alcoholism, aggression, musical differences

  • James Hetfield later described the firing as necessary for the band’s survival
  • Lars Ulrich acknowledged Mustaine’s songwriting contributions, but said the band had to make the call

“We had to let him go. It was a difficult decision, but the band was at stake.”

— James Hetfield, in a 2008 interview

The pattern: the same volatility that got him fired later fueled the aggressive sound of Megadeth.

Are Metallica and Dave Mustaine friends?

Current relationship status

The relationship has been strained for decades. Mustaine has publicly made peace several times, but the friendship remains complicated. He does not receive royalties from Metallica’s early work (Wikipedia).

Shared history and reconciliation attempts

  • In 2011, Mustaine joined Metallica on stage for a rare performance
  • In 2016, he said he had forgiven the band members
  • Occasional social media spats suggest old wounds still flare up

Royalties and credits

Mustaine is credited as a writer on four songs from Kill ‘Em All and two from Ride the Lightning, but he does not receive ongoing royalty payments (Wikipedia).

The trade-off

Fans get the songs, but Mustaine gets the credit without the cash — a reminder that rock history is written by the survivors with the legal rights.

Is Dave Mustaine a millionaire?

Net worth estimate

Multiple outlets estimate Mustaine’s net worth between $10 million and $14 million (HotNewHipHop (celebrity finance tracker)). He is widely considered a millionaire.

Sources of income: Megadeth, book, tours

  • Megadeth’s catalog and tours are his primary income
  • His forthcoming memoir In My Darkest Hour will likely add revenue
  • Has made real estate investments, according to some reports

Why this matters: compared to many thrash metal frontmen, Mustaine’s net worth is modest — but it’s enough to keep him independent and touring.

How long has Dave Mustaine been sober?

Sobriety start date 2002

Mustaine entered rehab in 2002 and has been sober ever since. He credits sobriety with saving his life and his career (Wikipedia).

Impact on his life and career

  • Before 2002, his drinking and drug use nearly destroyed Megadeth
  • After sobriety, Megadeth released a string of acclaimed albums including Dystopia
  • He has spoken openly about how sobriety allowed him to handle the cancer diagnosis

“If I hadn’t gotten sober, I would have died. The cancer would have been the end of me.”

— Dave Mustaine, speaking on his podcast

The catch: his earlier addiction cost him Metallica, but sobriety gave him the second act.

What song does Metallica refuse to play?

The Mechanix / The Four Horsemen dispute

Mustaine wrote the song originally titled “The Mechanix” while in Metallica. The band later rewrote it as “The Four Horsemen” and included it on Kill ‘Em All. Mustaine re-recorded his version on Megadeth’s debut Killing Is My Business… and Business Is Good! (Wikipedia). For more on his musical journey, you can read Jack Antonoff biography.

Fan demands to play the original

Metallica has rarely played the original version live, though they have occasionally dusted it off under fan pressure. The band’s reluctance is widely seen as an avoidance of Mustaine’s ghost.

The implication: one song holds the entire history of the rift — and both bands know it.
