CHICAGO (April 3, 2013)--Film critic Roger Ebert, 70, says he has cancer again and is scaling back his movie reviews while undergoing radiation.
In a blog post, Ebert said he'll take a "leave of presence."
The veteran critic has battled cancer in his thyroid and salivary glands and lost the ability to speak and eat after surgery.
In a lengthy essay posted late Tuesday, Ebert says the latest cancer was discovered after a "painful fracture" that made it difficult for him to walk.
The Pulitzer Prize winner was hospitalized late last year with a hip fracture.
Ebert wrote he's "not going away."
Instead, he'll write select movie reviews while leaving the rest of the work to a team of writers.
He also plans to spend time writing about his own health challenges.
