Def Leppard guitarist Vivian Campbell has cancer.  According to the AP, he's been in chemotherapy for two months and has four months of treatment left.  The 50-year-old guitarist has Hodgkin lymphoma.

Campbell, who also played in Thin Lizzy and Dio before joining Def Leppard in 1992 says, "I feel fortunate that my cancer sent me an alarm call in the form of `the cough that wouldn't quit.'"

The band will hit the road, with Campbell, on June 21st.
