Mark Hoppus has stage 4 lymphoma

Mark Hoppus is battling an aggressive form of lymphoma.

The Blink-182 star revealed last month he’s undergoing chemotherapy for cancer and he’s now shared further details about his illness, including the fact his blood is “trying to kill” him and he’s been diagnosed with a stage four form of the disease.

In a Twitch Q&A with Chilean fans, he said: “[I have] 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.

“So, I’m stage IV-A…The cancer isn’t bone-related, it’s blood-related. My blood’s trying to kill me.”

The ‘What’s My Age Again’ rocker has been undergoing intensive chemotherapy and has found the side effects tough.

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’s mother has battled the “exact form” of cancer he’s been diagnosed with so she’s proven to be a great source of help and support.

He said: “Oddly enough, we have the exact form of cancer.

“And she beat it, so I’ve been able to talk to her and bond with her quite a bit.”

The 49-year-old rocker has lost his hair as a result of his treatment but he’s managed to see the funny side.

He said: “I want to get the absolute worst toupee, so that it’s obviously not my hair, and just walk around and see how people look at me.”
