Uncle Jesse and Uncle Joey are forever family.

The bond of ‘Full House’ stars and friends John Stamos and Dave Coulier is stronger than ever. This became clear after Coulier revealed on Wednesday that he had been diagnosed with stage 3 non-Hodgkin’s lymphoma, People reports.

After the actor shared his diagnosis with the world, Stamos took to Instagram to show his longtime co-star some love and appreciation in a series of photos and videos. The photos come from various points in the couple’s decades-long friendship, from the “Full House” days to the present, including an image of the late “Full House” star Bob Saget. The caption read: “My brother from day 1. I love you @dcoulier and I will be by your side through it all.”

Coulier, 65, told People Magazine that he received his diagnosis after an infection caused swelling in his lymph nodes. “I went from, I got a little cold to I have cancer, and it was pretty overwhelming. This has really been a quick roller coaster ride of a journey,” he said. Coulier said he started chemotherapy immediately after his diagnosis in October and shaved his head as a “preemptive attack.”

Coulier was also on “The Today Show” with Hoda Kotb to share his experiences. “I look at this as a journey. If I can help people get a breast exam, a colonoscopy, or a prostate exam. Go do it, because for me, early detection meant everything,” he urged.

During that appearance, weatherman Al Roker, who also had cancer in 2020, hugged Coulier and told him he loved him.
