Social Distortion's frontman Mike Ness is battling tonsil cancer.
He posted on the band's social media that it was discovered during the pre-production of their new album.
He added that he was feeling well enough to continue recording until the day before he went into surgery.
He also said in three weeks he'll be starting radiation which should be the last of his therapy before he starts the healing process.
Ness says he's expected to make a full recovery.
Social Distortion has canceled their summer tour and the release of their new album will be delayed as he takes time to heal.
