Star of the 1978 classic musical Grease, Olivia Newton-John has been vocal about her health issues throughout the years.

Newton-John was diagnosed with breast cancer in the 1990’s but she regained her health and continued her music career.

She has celebrated over 25 years in remission, but she recently shared some heartbreaking news with fans about her health.

The 68-year-old singer recently visited her physician for nagging back pain, but it turned out to be something far worse than she imagined. After several tests, it was concluded that Newton-John’s breast cancer has spread to her sacrum, a portion of her spine.

The star has decided to postpone her tour taking place in the United States and Canada after receiving the news.

“The back pain that initially caused her to postpone the first half of her concert tour has turned out to be breast cancer that has metastasized to the sacrum,” stated a post on her official Facebook.

Although she may have to put her voice on pause, Newton-John is definitely not letting cancer win.

Fans are confident that Newton-John will have no problem beating her illness once again.

This star has all of our support as she fights breast cancer courageously, for the second time!
