Fox News contributor and syndicated columnist Charles Krauthammer says he has “only a few weeks to live” because of an aggressive form of cancer.

Krauthammer disclosed his doctors’ prognosis in a letter released Friday to colleagues, friends and viewers.

Krauthammer wrote that he underwent surgery in August to remove a cancerous tumor in his abdomen. While thought to be successful, he said there were complications that he was overcoming. However, he wrote recent tests revealed the cancer has returned and is “spreading rapidly.”

“There was no sign of it as recently as a month ago, which means it is aggressive and spreading rapidly,’ Krauthammer wrote. “My doctors tell me their best estimate is that I have only a few weeks left to live. This is the final verdict. My fight is over.”

Krauthammer says he will “leave this life with no regrets.”

The 68-year-old New York native was raised in Montreal. He was a first-year medical student at Harvard in 1975 when a diving accident paralyzed him from the neck down and put him in a wheelchair for life. He became a successful psychiatrist and first emerged in the political sphere as a speechwriter for Vice President Walter Mondale during the Carter administration.

He later developed a career as a Pulitzer Prize-winning author and commentator.

Before I met and wrote about Charles Krauthammer, I thought there were three basic kinds of Jews, religiously speaking: Reform, Conservative, Orthodox. He taught me a new category. "I consider myself a Shinto Jew," he told me. "I engage in ancestor worship."
