Mark Hoppus has once again given an update on his health, announcing that his cancer is in remission, according to PEOPLE.

On Thursday, the 49-year-old singer revealed that he has undergone surgery to remove his chemo port after seeking treatment for stage 4 diffuse large B-cell lymphoma.

Sharing the news of the procedure alongside a masked selfie, Hoppus wrote on Twitter, “In the waiting room for the surgery to remove my chemo port!”

A chemo port is a small device attached to a vein that helps deliver cancer drugs used in chemotherapy.

Hoppus later shared a picture of his arm “before” the surgery on his Instagram Stories. The port was still under his skin in that image.

The bassist and co-lead vocalist of the rock band Blink-182 then followed up with a photo of the port itself, captioning the image, “During,” ending his series of posts by sharing a snapshot of his arm patched up after the medical device was removed.

Large B-cell lymphoma is a type of cancer that occurs in white blood cells and can form tumors throughout the body, according to the Mayo Clinic. It is one of the most common subtypes of non-Hodgkin’s lymphoma.

Hoppus first revealed his cancer diagnosis in late June, sharing more about the disease during a Twitch Livestream in July, telling fans at the time, “My blood’s trying to kill me.”

In August, he updated his fans about finishing his fifth round of chemotherapy. He wrote on his Twitter at the time that he was “grateful to not be going in” for more treatments.

In late September, Hoppus announced that he is “cancer-free,” adding, “Thank you God and universe and friends and family and everyone who sent support and kindness and love.”

“Still have to get scanned every six months, and it’ll take me until the end of the year to get back to normal,” he continued, “but today is an amazing day and I feel so blessed. Can I get a W in the chat?”
