The Blink-182 bassist and singer revealed Tuesday that his cancer is "blood-related," rather than "bone-related" during a virtual Q&A session on YouTube with Blink-182 fans in Chile. "My classification is diffuse large B-cell lymphoma Stage 4-A, which means, as I understand it, it's entered four different parts of my body," Hoppus explained. "I don't know how exactly they determine the four-part of it, but it's entered enough parts of my body that I'm Stage 4 , which I think is the highest that it goes. So, I'm Stage 4-A." According to Mayo Clinic, diffuse large B-cell lymphoma (DLBCL) is a type of cancer that starts in white blood cells and can eventually form tumors throughout the body.
