Wanda Sykes says she underwent a double mastectomy after she was diagnosed with breast cancer in February.

The U.S. actress and comedian, 47, made the revelation during an interview for "The Ellen DeGeneres Show" set to air Monday, E! News said.

During her chat with DeGeneres, Sykes said the disease was discovered when she was preparing to have breast-reduction surgery.

"I was very, very lucky," E! quoted Sykes as saying, "because DCIS [ductal carcinoma in situ] is basically stage zero cancer. So I was very lucky. But cancer is cancer. I had the choice of, you can go back every three months and get it checked. Have a mammogram, MRI every three months just to see what it's doing. But I'm not good at keeping on top of stuff. I'm sure I'm overdue for an oil change and a teeth cleaning already. I have a lot of breast cancer history on my mother's side of the family, which I didn't know about. Do you want to wait and not be as fortunate when it comes back and it's too late?"

Sykes is known for her work on TV's "The New Adventures of Old Christine," "Curb Your Enthusiasm" and "The Wanda Sykes Show."
