Mark Hoppus is responding to chemotherapy. The Blink-182 star is currently battling an aggressive form of lymphoma, but revealed on Monday (19.07.21) there is some hope for him as his body has been reacting positively to his first rounds of treatment. He wrote in a post on Twitter: âScans indicate that the chemo is working! I still have months of treatment ahead, but itâs the best possible news. âIâm so grateful and confused and also sick from last weekâs chemo. But the poison the doctors pump into me and the kind thoughts and wishes of people around me are destroying this cancer. Just gonna keep fighting⦠(sic)â
