Travis Barker and Tom DeLonge are leading messages of love and support for their Blink-182 bandmate Mark Hoppus after the bassist announced he is undergoing treatment for cancer.

In a post on his Twitter account on Wednesday, the 49-year-old revealed he has been receiving chemotherapy treatment for the past three months.

He followed up the announcement with a post on his Instagram story, sharing a photo of himself in the hospital with the caption: "One cancer treatment, please."

Drummer Travis, who has been bandmates with Mark since 1998, shared his sentiments in a statement to E! News.

Meanwhile guitarist Tom DeLonge, who left Blink-182 in 2015, tweeted his own message of support, calling his former bandmate "a super-human who is pushing through this difficult obstacle with a wide-open heart."
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
