Mark Hoppus is getting more detailed about his cancer diagnosis.
In a recent Twitch Q&A with fans in Chile, the Blink-182 bassist said he has "diffuse large B-cell lymphoma."
"My classification is stage IV-A, which means, as I understand it, it's entered four parts of my body. 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 IV, which I think is the highest that it goes," he said. "So, I'm stage IV-A…The cancer isn't bone-related, it's blood-related. My blood's trying to kill me."
The rocker first revealed that he had cancer last month, and noted that he had been undergoing chemotherapy treatments.
"Let me tell you something that is real and it absolutely sucks: A side effect of the chemotherapy is you get something called 'chemo brain,'" he explained. "And for me, I forget things that I should have on-call, like names, song titles, anything. People will be talking to me and five minutes later I'll ask them a question, and they'll be like, 'I just told you that five minutes ago.'"
In detailing what he's been going through, he said, "The first chemo, I felt like I was a zombie that fell onto an electric fence and was just being shocked. The second round of chemo, I just felt very weak and tired. Really just like the worst flu ever. The third round of chemo, I started retching. Nauseous and that whole thing."
Mark mentioned that he might undergo a bone marrow transplant if the chemo doesn't work.
"We're beating this cancer," he said. "It's just a matter of time."
On July 4, Mark shared a photo with a bald head, a result of the treatments. He laughed off his new look.
"I want to get the absolute worst toupée," he says, "so that it's obviously not my hair, and just walk around and see how people look at me."
According to the Lymphoma Research Foundation, more than 18,000 Americans are diagnosed with diffuse large B-cell lymphoma annually. It's the most common type of non-Hodgkin lymphoma in the country.
