Julia Louis-Dreyfus, known for her roles on Seinfeld, Veep, and The New Adventures of Old Christine, has just announced some major news about her health.

Louis-Dreyfus has been a pioneer in women's comedy since her iconic role as Elaine on Seinfeld.

The mom-of-two just won her sixth consecutive Emmy award for her role on Veep, where she plays the vice president of the United States. Her win broke the previous record for number of Emmys win by a performer in a single role.

Louis-Dreyfus has always been known for her healthy lifestyle and diet, crediting her family as her inspiration.

"I love vegetables. I should be a vegetarian, and I feel guilty saying I'm not," she said. "But I like meat and chicken. So I buy organic foods whenever they're available and shop at my local farmers market whenever I can."

"I have two growing boys," she said of her sons Henry, 16, and Charles, 11 with husband Brad Hall. "I'm concerned about what goes in their bodies."

But no amount of diet and exercise could keep her immune from what she's been diagnosed with.

Julia Louis-Dreyfus herself just posted about her diagnosis on Instagram.

"1 in 8 women get breast cancer. Today, I'm the one," Louis-Dreyfus wrote. "The good news is that I have the most glorious group of supportive and caring family and friends, and fantastic insurance through my union. The bad news is that not all women are so lucky, so let's fight all cancers and make universal healthcare a reality."

Louis-Dreyfus joins the likes of Shannen Doherty, Olivia Newton-John, Sheryl Crow, Melissa Ethridge, and Edie Falco as celebrities who have also battled breast cancer. They have all overcome the disease.

Celebrities are speaking out on Louis-Dreyfus's diagnosis:

"Sending you so much love and light," wrote actress Olivia Munn on Instagram.

"Our love and support go out to Julia and her family at this time," HBO said in a statement. "We have every confidence she will get through this with her usual tenacity and undaunted spirit, and look forward to her return to health and to HBO for the final season of Veep."
