Jeff Bridges' tumor has "drastically shrunk".
The 71-year-old screen legend revealed three months ago that he was diagnosed with lymphoma.
And in an update to his fans this week, he shared how “elated” he was after his CAT scan showed a significant reduction in the size off the cancerous mass.
Jeff wrote on his website: “January 6th I go in for CAT scan to see if my new protocol is shrinking my tumor. Turns out it’s working beautifully,” Jeff wrote on his website. “The thing has drastically shrunk. I come home elated with the news. (sic)"
The 'Big Lebowski' star found out his positive news on January 6, the same day angry Trump supporters stormed the Capitol building in Washington, DC.
He added: “I turn on the TV to find out what’s going in the world, and….well…I don’t have to tell you what’s goin’ on. To see our country attacking itself broke my heart. A question rose in me – what’s an individual to do in a situation like this? My mentor, Rozzell Sykes, came to mind. His manta was Be Love. (sic)"
Last month, Jeff revealed he had shaved his head and got a new canine companion and insisted he's "feeling good".
Alongside a photo uploaded to Instagram showing his shaved head, Jeff lay back with his pup Monty on his lap and smiled for the camera.
He wrote: "Heer’s the latest: "Feeling good
"Shaved my head
"Got a puppy - Monty
"Had a Birthday - 71, man (sic)"
After his diagnosis, Jeff was inundated with thoughtful messages and admitted at the time that all the love he's received feels like "some kind of positive virus".
He wrote on the site: "This cancer thing is bringing on feelings of precociousness & gratitude & good old fashion love & lots of it, big time. I'm feeling so much of it comin' my way, & man I appreciate it.
"It's contagious, all this love, like some kind of positive virus. I want to acknowledge & thank you guys for reaching out during this time. It feels good, getting all the well wishes & love!
"This cancer is making me appreciate my mortality, appreciate impermanence.
"I'm realizing if I have s*** to share, now's the time. (sic)"
In October, he announced he was starting treatment for the cancer, which develops in the cells of the immune system known as lymphocytes.
He rolled back the years as his iconic character The Dude from 1998 movie 'The Big Lebowski' to update his fans on his health, and admitted that "the prognosis is good".
Jeff wrote: "As the Dude would say.. New S*** has come to light. 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.
"I’m starting treatment and will keep you posted on my recovery."
