Julia took to Instagram to announce her diagnosis in late September last year, just weeks after taking home her record sixth Primetime Emmy Award for her role as Selina Meyer in the comedy Veep.

She wrote a message to fans, saying: "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 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 health care a reality."
