Irish writer Emma Hannigan has died after an 11-year battle with cancer at the age of 45.
The author was diagnosed with cancer for the first time in 2007. She had fought the disease ten times since then before passing away on Saturday, March 3.
Breast Cancer Ireland announced the news on Saturday afternoon, writing on Facebook and Twitter: "Breast Cancer Ireland wish to extend our deepest sympathies to the family of our dear friend Emma Hannigan who lost her battle with cancer earlier today. May she rest in peace."

The author revealed in mid-February that her long-term battle with breast cancer had become terminal.
She wrote in a blog post: "The conversation I never wanted to have has been said.
"My medical team have thrown everything but the kitchen sink at this fight but all avenues have now been exhausted.
"To say that I’m heartbroken doesn’t begin to cover it".
All good things must come to an end... https://t.co/zcpLRyp9nG— Emma Hannigan Author (@MsEmmaHannigan) February 16, 2018
After the blog post was published, a campaign was launched on social media to get her new new book, Letters to my Daughters, to number one in the Irish book charts.
The book has since soared to number one in the charts, with booksellers Dubray Books announcing that they are donating the profits from the book to the Irish Cancer Society.
The mother-of-two also started a fundraising campaign to raise money for Breast Cancer Ireland which has raised over €100,000 so far.
She tweeted after the fundraising target had been reached. "It's never too late to dream big, keep dreaming.
"Thank you so much, please keep those donations coming in and don't stop until we reach the top."
