The singer and guitarist of the heavy metal band announced the news on social media Monday, writing that he’s “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.”
The 57-year-old says as a result, Megadeth has to cancel “most shows this year,” though the 2019 Megacruise will happen “and the band will be a part of it in some form.”
Mustaine adds he and his bandmates, David Ellefson, Kiko Loureiro and Dirk Verbeuren, are in the studio working on a new album. It will be the follow-up to 2016’s “Dystopia,” which won the band their first-ever Grammy Award in 2017.
