Olivia Newton-John diagnosed with cancer for third time

'Grease' star Olivia Newton-John said she has since undergone radiation treatment

Olivia Newton-John, the Australian singer who found worldwide fame in the hit movie "Grease", has revealed she has been diagnosed with cancer for the third time.

The 69-year-old told Australian television broadcaster Channel Seven that doctors had discovered a tumour at the base of her spine.

She has since undergone radiation treatment, and is also treating the disease with natural therapies such as the use of cannabis oil.

"I'm still treating it, and I'm treating it naturally and doing really well, yeah," she told the network late Sunday from her home in California.
