Mark also thanked fans for their well wishes, and detailed what he's been up to – when feeling physically up to it.
"On good days, I go do stuff," he said. "I went on a walk outside today and it was the first time I’d left my house in like… five days pretty much. But this round of chemo I wasn’t totally stuck on the couch, miserable. I’ve actually watched movies and walked around and cleaned the house and hung out with my dogs.
"I didn’t just feel like a poisoned electrified zombie leaning up against an electric fence like I did the rest, the past couple of rounds.
"I can’t go anywhere right now," he added. "I wanted to go to the Dodgers last night – I can’t. I want to go hang out with friends and go to a restaurant – I can’t. My white blood cell count is way too low for me to go out so I am stuck trying to get better. That’s alright, I’ll take it."
blink-182 bandmate Travis Barker told E! News last week: "Mark is my brother and I love and support him. I will be with him every step of the way onstage and off and can’t wait for us to play together again soon.”
Former blink frontman Tom DeLonge also said: "I too, have been aware of Mark Hoppus’ cancer diagnosis for awhile now. And to add to his own words that he used today, I would also like to say that he is strong, and a super-human who is pushing through this difficult obstacle with a wide-open heart. #WeHaveHisBack”
