51-year-old DEF LEPPARD and LAST IN LINE guitarist Vivian Campbell recently spoke to Lymphoma Association about being diagnosed with Hodgkin's lymphoma. Check out the clip below.Campbell, who joined LEPPARD in 1992 after stints in DIO and WHITESNAKE, has been receiving chemotherapy since April. "I feel fortunate that my cancer sent me an alarm call in the form of 'the cough that wouldn't quit,'" Campbell said earlier in the year. Hodgkin's lymphoma is a cancer of the immune system characterized by the painless enlargement of lymph nodes, spleen, or immune tissue. "I did kind of want to not go public with it at first, because it is a weird kind of thing," Campbell said in a June radio interview. "You've got to kind of learn to deal with it on your own terms before you can address the rest of the world about it. So, you know, I feel very comfortable going public about it. For the first couple months, I even tried to keep it from my children, because they were still in school and doing exams and stuff and I didn't want to add to their concerns. But after a while, it's inevitable that you, you know, something's going on and you have to kind of come out with it and kind of explain what the situation is. But I'm very comfortable with it. I'm very comfortable with the treatment. I'm very comfortable with how my body is reacting to it." DEF LEPPARD's recent Las Vegas extravaganza will hit the silver screen for two nights in October. NCM Fathom Events together with AEG Live and Network Live are bringing DEF LEPPARD "Viva!
