Olivia Newton-John’s Daughter Speaks On Mom’s Cancer Diagnosis

Chloe Lattanzi

Nothing can stand in Olivia Newton-John’s way while she battles a recurrence of cancer, and her daughter, Chloe Lattanzi, will be there by her side to support her until she wins.

Lattanzi took to Instagram on Wednesday to “thank all of you for your love and support” after the singer, 68, announced Tuesday that she was putting her U.S. and Canadian tour on hold after discovering she has breast cancer that has metastasized to the sacrum, according to the statement.

“My mom and best friend is going to be fine! She will be using medicine that I often talk about. CBD oil (cannabidiol oil)! And other natural healing remedies plus modern medicine to beat this,” Lattanzi said of her mother, who is currently “resting and going through treatment,” a source close to the Grammy winner previously told PEOPLE. “Cancer is the disease of our generation and it is part of my and my mother’s quest to beat this insidious monster.”

“We both love you all, and anyone fighting this disease you can beat it,” she added. “Look for natural remedies as well as what modern medicine can offer. My mom is so powerful she will beat this in no time. All my love to you. And I wish you health, wealth and happiness.”

Just two weeks ago, Newton-John postponed the first half of her concert tour because of severe back pain from what she thought was sciatica, but further testing found it was actually cancer that had spread.

“She plans to be touring in August. They’re all very positive,” a source close Newton-John told PEOPLE on Tuesday about Newton-John and her family.

Aside from natural healing therapies, the entertainer will be treated with a “short course of photon radiation therapy,” adds the statement. However, Newton-John is “confident she will be back later in the year, better than ever, to celebrate her shows.”

“I decided on my direction of therapies after consultation with my doctors and natural therapists and the medical team at my Olivia Newton-John Cancer Wellness and Research Centre in Melbourne, Australia,” says the singer, who first battled breast cancer 25 years ago.
