Al Roker has given fans a positive update about his health.

On Thursday, the 66-year-old weather forecaster posted a picture of himself and his wife, Deborah Roberts, ABC News reporter, on Instagram to share that he had undergone prostate cancer surgery and is back home now.

He wrote, “Relieved to let you all know that my #prostatecancer surgery is done and back home. Big shoutout to everyone at the #josierobertsonsurgerycenter and so appreciate all the thoughts and wishes from our viewers and the wonderful care packages from my co-workers. Hope to see you all soon.”

Roker also posted another photo, giving a thumbs-up while standing next to his 18-year-old son, Nick.

He underwent the surgery at Memorial Sloan Kettering Cancer Center in New York City, performed by Dr. Vincent Laudone.

Last week, Roker revealed he had been diagnosed with prostate cancer during an episode of TODAY, sharing his plan to undergo a prostatectomy, surgical removal of the prostate gland.

He said, “It’s a good news-bad news kind of thing. Good news is we caught it early. Not great news is that it’s a little aggressive, so I’m going to be taking some time off to take care of this.”

“We’ll just wait and see,” he added, “and hopefully in about two weeks, I’ll be back (on TODAY).”

Appearing on TODAY, Dr. Laudone explained why he believed Roker’s surgery was necessary.

The surgeon said, “Fortunately his cancer appears somewhat limited or confined to the prostate, but because it’s more aggressive, we wanted to treat it, and after discussion regarding all of the different options — surgery, radiation, focal therapy — we settled on removing the prostate.” After getting an MRI and a biopsy, Roker was diagnosed with prostate cancer on September 29.
