olivia newton john sister rona brain cancer Olivia Newton John's sister Rona Newton John dies of brain cancerOlivia Newton-John, who became an advocate for breast cancer research after she was diagnosed with it two decades ago and underwent a double mastectomy, has revealed that her sister Rona Newton-John (above, left) passed away last Friday (May 24) from brain cancer.

Rona was diagnosed just a few weeks ago, causing Olivia to postpone her Las Vegas show so the sisters could spend time together.

Olivia writes on Facebook:

beautiful sister Rona sadly passed on May 24th in Los Angeles. It was
May 25th in Australia – which was our mother Irene’s birthday. Rona died
of a very aggressive brain tumor and mercifully suffered no pain. She
was surrounded by the love of her four children – Fiona, Brett,Tottie
and Emerson and, her wonderful friends. I will miss her forever – my
beautiful, smart, talented, funny, brave sister Rona.

In lieu of flowers the family would appreciate donations to the ONJCWC where a brain tumor wellness program will be
started in her name. Thank you all for your kind words of love and

Love and light,

Newton-John also includes a link to the brain tumor wellness program, if you’d like to donate.
