publicly showed his support after announced his stage 3 non-Hodgkin lymphoma diagnosis.

“My brother from day 1,” Stamos, 61, wrote via Instagram on Wednesday, November 14, alongside photos of him and Coulier, 65, over the years. “Love you @dcoulier and I’ll be by your side through it all.”

Coulier was diagnosed with the “very aggressive” cancer in October after an upper respiratory infection caused severe swelling of his lymph node.

“I went from, I got a little bit of a head cold to I have cancer, and it was pretty overwhelming,” he revealed to People on Wednesday, noting it hadn’t spread to his bone marrow. “At that point, my chances of curable went from something low to [the] 90 percent range. And so that was a great day.”

Coulier recalled how he told his former Full House cast members the news, adding, “I didn’t want them to hear it from someone else, so I sent a text message out. It was just this outpouring of, ‘I will be there. You just name the time, and I know you’re in great hands with [wife Melissa Bring], but what can we do?’ It really is overwhelming the love that we have for each other. We’ve been there for so many years for each other, and it’s pretty remarkable.”

Coulier is expecting a visit from Stamos later this week as he undergoes chemotherapy treatment.

“He goes, ‘If you want to just sleep, I’ll just sit by you. Or if you want to listen to music or just talk, whatever,’” Coulier recalled Stamos telling him. “And I’m just like, ‘Wow. That’s, like, a brother. That’s just truly a brother.’”

Full House, which ran from 1987 to 1995, followed Danny () as he attempted to raise his three daughters — D.J. (), Stephanie () and Michelle ( and ) — after his wife’s death. Danny’s brother-in-law, Jesse (Stamos), and best friend Joey (Coulier) subsequently moved in to help him out.
