Def Leppard guitarist Vivian Campbell announced Saturday that his cancer has returned, sidelining him from the group’s upcoming tour.

“I'm saddened by the fact that my cancer has returned. However, I'm beyond consolation that it's return will prevent me from being able to do my job for a while,” Campbell wrote on Facebook. “I’m still working on a schedule of treatment with my doctors, but I will see you all very soon. My apologies.”

Campbell was first treated for Hodgkin’s Lymphoma, cancer of the white blood cells, in 2013. He said last year that he wanted to receive stem-cell treatment. As Ultimate Classic Rock notes, the cancer did come back in September, but after the stem-cell transplant, things were looking better until yesterday’s announcement.

The group is set to tour with Styx and Tesla for over three months. Previously, Trixter guitarist Steve Brown filled in for the “Pour Some Sugar On Me” band, but the group hasn’t confirmed if he will join them again.
