Louis-Dreyfus' most recent role has been starring as the fictional Vice President Selina Meyer in the political satire Veep, but the final season has been postponed until she has completed her treatment and is ready to return to work.
The actress has shared her cancer story with her fans via social media with regular posts on her Twitter and Instagram accounts and throughout her ordeal she has been able to maintain her sense of humour.
When sharing the news of her diagnosis, Louis-Dreyfus posted: "1 in 8 women get breast cancer. Today, I'm the one. The good news is that I have the most glorious group of supportive and caring 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 health care a reality."
