The cancer-stricken Womack also is scheduled to undergo surgery at a later date.
In a statement through his New York publicist, the 68-year-old Womack thanked his fans for their prayers, love and well wishes, and says he looks forward to when he tours in support of his upcoming album.
The Rock and Roll Hall of Fame inductee is known for such hits as "Lookin' For a Love," and "That's the Way I Feel About Cha." Womack also wrote the early Rolling Stones' hit "It's All Over Now."
"The Bravest Man in the Universe" comes out later this summer on XL Recordings. It's produced by Womack, Damon Albarn and Richard Russell.
