Hoppus’ former bandmate, Tom DeLonge, took to Twitter to show his support for the Blink-182 bassist:

I too, have been aware of @markhoppus’s 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

Hoppus formed Blink-182 with DeLonge and Scott Raynor back in 1992 in California. DeLonge departed the band in 2015, which left Hoppus as the lone original member.

The band’s latest album, Nine, was released in 2019.
