Mark Hoppus is staying hopeful after his cancer diagnosis.
The Blink-182 singer, who recently revealed he has stage 4 diffuse large B-cell lymphoma, gave fans an optimistic health update on Monday, July 19.
"Scans indicate that the chemo is working!" he tweeted. "I still have months of treatment ahead, but it's the best possible news."
Mark, 49, shared, "I'm so grateful and confused and also sick from last week's 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…" added the musician, who shares 18-year-old Jack Hoppus with his wife of 20 years, Skye Everly. He later joked that it should be "Chemotherapy Gary" in place of their song title "Dysentery Gary."
Last week, Mark told his followers his cancer is not bone-related but rather blood-related, saying, "My blood's trying to kill me... It's entered four different parts of my body."
He was diagnosed in April and has recently been undergoing chemotherapy. "The side effect of the chemotherapy is you get something called 'chemo brain'...I forget people's names, song titles, anything," he said. "People will be talking to me, and then five minutes later I'll ask them a question and they're like, I just told you that five minutes ago."
Mark has been looking forward to healthier days ahead in his positive social media posting, writing in June, "I still have months of treatment ahead of me but I'm trying to remain hopeful and positive. Can't wait to be cancer free and see you all at a concert in the near future. Love to you all."
His bandmate Travis Barker is certainly sending him love, telling E! News in a statement, "Mark is my brother and I love and support him. I will be with him every step of the way on stage and off and can't wait for us to play together again soon."
