Jim Beaver, known for roles on the shows The Boys and Supernatural, has privately undergone a fight for his life.

In a Feb. 3 Facebook post, the actor revealed that he had battled prostate cancer and, after undergoing treatments and surgery in Texas, is now cancer-free.

"I had kept this largely to myself the past few years, but as someone has made a rather public announcement of it in comments on my page in the past few days, I think that it is time to be fully public about it," the 72-year-old wrote. "In the fall of 2018, I was diagnosed with aggressive prostate cancer."

Beaver, who plays Secretary of Defense Robert Singer on The Boys and portrayed Bobby Singer on Supernatural, said he underwent six months of hormone treatments at M.D. Anderson Cancer Center in Houston, Texas "to reduce my testosterone levels, so that my angry red prostate could cool down and not be so cancerously active when it came time to cut it out, thus lessening the chance of spread."
