Mark Hoppus, who is best known as the bassist and co-lead vocalist of the rock band Blink-182, has recently talked about his cancer diagnosis.

The 49-year-old singer shared an inspiring message on Twitter, thanking fans for their support as he is undergoing treatment for his cancer. He also revealed that he will be undergoing a test to determine the seriousness of his cancer.

He tweeted, “Apologies if I’m oversharing but it’s so surreal to think that this week I’ll take a test that may very well determine if I live or die. Thanks to everyone for the positive thoughts and encouragement. I read all your replies and it means the world to me.”

The musician shared an X-ray image on which he drew a circle, revealing that there is a sizable mass.

Hoppus wrote, “I’m going to beat this through chemotherapy or through bone marrow transplants, but either way I’m determined to kick cancer’s ass directly in the nuts. Love to you all. Let’s. Heckin. Go.”

The singer first revealed his cancer diagnosis on June 23, stating that for “the past three months I’ve been undergoing chemotherapy for cancer.”

Last month, he wrote on his social media accounts, “I have cancer. It sucks and I’m scared, and at the same time I’m blessed with incredible doctors and family and friends to get me through this.”

He said he had “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 hopefully near future.”

Hoppus, however, did not disclose any more details about his cancer diagnosis. He has been updating fans on his cancer treatment. He recently opened up about undergoing chemotherapy during a 45-minute stream of Blinko on Twitch.

Earlier this month, Hoppus tweeted, “Everything about chemo sucks except the part where it hopefully saves my life.”

He then revealed that he has created what he called a “cancer garden” filled with “mutated varieties” of cacti while undergoing treatment.

“I put together a little cancer garden in the yard with mutated varieties because I feel connected to them through my own cells’ mutation,” he tweeted. “I sit here in the morning with them, drinking my coffee, and we’re like ‘well this is weird.’”
