Def Leppard guitarist Vivian Campbell is “doing extremely well” after his latest treatment for Hodgkin’s lymphoma according to his doctor.

Diagnosed in 2013, Campbell has gone through rounds of chemotherapy and a failed stem cell transplant. The type of lymphoma that Campbell has is identified as cancer found within white blood cells.

When talking about the cancer, Campbell said, “I’ve always been a glass half-full kind of person, but now with cancer, my glass is brimming. You really kind of recalibrate your thinking about each and every day in life. You look at your life a different way and you look at your priorities a different way. It helped me become a better guitar player. It helped me look inward. … It’s just been good for me. I kind of always look at it as when life gives you these sorts of obstacles, you have two choices. You can give in or you can fight, you know?”
