Olivia Newton-John says she has been diagnosed with cancer for the third time in three decades. The four-time Grammy winner, who will turn 70 on Sept. 26, told Australian news program Sunday Night that doctors found a tumor in her lower back in 2017.
Newton-John says she's “treating it naturally and doing really well."
"I believe I will win over it,” she says.
The Grease star says she is taking cannabis oil — made from marijuana her husband grows in California — for the pain. She has undergone radiation treatments and cut sugar out of her diet.
Newton-John says she hopes her native Australia will legalize medical marijuana.
She was first diagnosed with breast cancer in 1992, undergoing a partial mastectomy and reconstruction. She was diagnosed with breast cancer again in 2013.
