Julia-Louis Dreyfus has breast cancer.
ET has learned that the Veep star learned of her diagnosis the day after her historic Emmys win. On Thursday, Louis-Dreyfus broke the news to fans in a heartbreaking note posted to Twitter.
"One in eight women get breast cancer. Today, I'm the one," the 56-year-old actress revealed. "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," she added. "So let's fight all cancers and make universal healthcare a reality."
Our love and support go out to Julia and her family at this time," HBO said in a statement to ET following Louis-Dreyfus' cancer news. "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."
