Vivian Campbell is on the mend after completing the latest round of treatment for his Hodgkin’s lymphoma.

As previously reported, Campbell agreed to undergo a stem cell transplant in order to combat the disease, which doctors recommended after a resurgence (and subsequent remission) following the treatment he received after his initial diagnosis.

Campbell's surgery prevented him from joining Def Leppard for a recent round of tour dates, and Trixter guitarist Steve Brown stepped in as a substitute guitarist during his absence, but Campbell vowed to be back in action by early 2015 -- and as Def Leppard singer Joe Elliott recently revealed, he's well on his way to achieving that goal.

In fact, as Campbell told friends and followers in a Facebook note posted on Nov. 11, he's out of the hospital and focused on his recovery. "Home ... So glad that's over," reads the post. "Time to recover/recuperate and grow some hair. Thanks for all the love you've sent -- much appreciated! Normal service will be resumed shortly."

Campbell's convalescence comes during a brief lull for the band, which plans to have a new album out next year. In the meantime, Elliott will hit the road for a brief series of shows with his Down N Outz side project, while guitarist Phil Collen continues work on the debut full-length effort from his new side project, the band Delta Deep. Meanwhile, Campbell's other band, Last in Line, has its own album in the works.
