A comedian best known for her role on one of HBO’s longest-running series revealed that she has been battling breast cancer, E! Online reports.

Wanda Skyes, who has a recurring role on "Curb Your Enthusiasm," opened up during an interview on the syndicated talk show “Ellen,” which is set to air Monday. Sykes revealed that while having breast-reduction surgery, she learned that she had breast cancer and chose to have a complete mastectomy, according to the story.

Sykes reportedly said during the interview that the cancer was detected in just her left breast, but to prevent the spread of the disease, she opted to remove both breasts.

Despite her health issues, Skyes was very positive and told host Ellen DeGeneres, "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."

Sykes talked about how the diagnosis was related to her decision to have breast-reduction surgery. "I had real big boobs, and I just got tired of knocking over stuff,” she tole DeGeneres, according to the story. “Every time I eat — Oh, lord. I’d carry a Tide stick everywhere I go. My back was sore, so it was time to have a reduction. It wasn’t until after the reduction that, in the lab work, the pathology, that they found that I had DCIS [ductal carcinoma in situ] in my left breast.”
