Legendary singer-songwriter John Prine has been diagnosed with a form of lung cancer.

The 67-year-old broke the news on his website on Thursday (Nov. 21), when he announced that he will be postponing two upcoming concert dates. “There’s nothing I hate more than canceling shows,” Prine says, noting that all dates will be honored.

“I’ve been diagnosed with non-small cell carcinoma of the lung," he adds. "Doctors here in Nashville have caught it early, and it is operable. They see no reason why I won’t fully recover.”

Prine, whose hits include 'Angel From Montgomery,' has been inducted into the Nashville Songwriters Hall of Fame, and was presented with a Lifetime Achievement Award by the Americana Music Association in 2003. His career is currently the subject of an exhibit at the Country Music Hall of Fame and Museum.

The Grammy-winning music legend previously underwent treatment for cancer in the late '90s. "This is a different form of cancer, unrelated to what I had in 1997," he states.

The Boot extends our well wishes to John Prine for a quick and full recovery.
