Julia Louis-Dreyfus, known for her roles on Seinfeld, Veep, and The New Adventures of Old Christine, announced in September that she was diagnosed with breast cancer.

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.

"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."

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 won by a performer in a single role.

Now, almost one month after she revealed her cancer diagnosis, Julia Louis-Dreyfus has provided an update on her treatment.

Dreyfus posted a picture of her at the hospital, announcing she had completed her second round of chemotherapy.

Dreyfus quoted Katy Perry's hit song "Roar" in her Instagram post, saying it gave her inspiration.

"Chemo #2 finito. We are NOT f--king around here," Julia shared.  "I've got the eye of the tiger. The Fighter dancing through the fire cuz I am a champion and you're going to hear me ROAR. Thanks to @mrtonyhale & @timothycsimons & @katyperry for their hilarious and loving inspiration."

According to E! News, Dreyfus completed her first round of chemo just one day after the 2017 Emmy Awards.
