On Monday night, Academy Award–winning actor Jeff Bridges announced on Twitter that he has lymphoma, a type of cancer that begins in the lymphatic system and occurs when white blood cells of the immune system grow out of control, NPR reports.

“As the Dude would say..New S**T has come to light,” Bridges tweeted, referencing the iconic character he played in the 1998 film The Big Lebowski. “I have been diagnosed with Lymphoma. Although it is a serious disease, I feel fortunate that I have a great team of doctors and the prognosis is good.”

Bridges informed the public that he was starting treatment and would keep everyone updated on his recovery. The 70-year-old actor didn’t provide additional details about his diagnosis, such as the type of lymphoma, the stage of his cancer or the treatment he would be undergoing, but he did thank his family, friends and fans for their support. He also encouraged everyone to vote.

“Thank you for prayers and well wishes,” he wrote. “And while I have you, please remember to go vote. Because we are all in this together. Vote.org. Love, Jeff.”

Bridges, who has been acting since the 1950s and has been nominated for seven Academy Awards, is currently in production on the drama series The Old Man, which is slated to premiere on FX and Hulu in 2021.

Based on the best-selling novel of the same name, the show follows Dan Chase—played by Bridges—a man who absconded from the CIA decades ago and has been living off the grid since, according to Variety. When an assassin arrives and attempts to kill Chase, he must reconcile with his past to ensure his future.

“Our thoughts go out to Jeff and his family during this challenging time, and they have our love and support,” said Touchstone Pictures and FX Productions in a joint statement. “We wish him a safe and full recovery. And, as Jeff always says, ‘We are all in this together.’ Jeff, we are all in this together with you.”
