Dave Mustaine isn’t letting something like cancer get him down, having already returned to the studio to work on the new Megadeth album.

Just over a week ago, the world of music was learning that Megadeth leader Dave Mustaine has been diagnosed with throat cancer.

“It’s clearly something to be respected and faced head on – but I’ve faced obstacles before,” the rocker revealed. “I’m working closely with my doctors, and we’ve mapped out a treatment plan which they feel has a 90% success rate. Treatment has already begun.”

While this news was undoubtedly troubling, Megadeth also announced that they had cancelled almost all touring plans for the near future, but assured fans they were still “working on the follow up to Dystopia – which I can’t wait for everyone to hear.”

Then, earlier this week, Dave Mustaine took to Facebook to thank everyone for their support during this difficult time.

“I wanted to take a moment real quick and thank my family, my friends and the best fans in the world for all of your support and love the last few days,” Mustaine stated. “We’re gonna beat this thing together.”

Now, it seems that his tenacious nature is really shining through, with the rocker having already hit the studio once again.

Taking to Instagram recently, Megadeth drummer Dirk Verbeuren shared a shot of Dave Mustaine with a guitar in his lap while in the studio.

“Dave Mustaine working on #megaalbum16 like a true warrior,” Verbeuren wrote. “Let’s keep Dave and his family in our thoughts.”

In related news, Mustaine had gone on record to say that the upcoming Megadeth album is the product of some hectic recording sessions, having gone and above what their record contract asks of them.

“I have about eight songs and there’s one which is just unanimously everyone’s favorite, which is great,” Mustaine stated. “I’m not saying there’s only one good song so far though, haha!

“Let’s just say whenever I have that first song everyone gets excited about, I know I’m on my way to another great record.

“We’re going to do 12 or 13 tracks this time. My contract says I’m only supposed to do eight songs a record and I just can’t do that — it feels like cheating.”
