The 68-year-old singer and actress announced on Tuesday that she would be postponing her concert tour dates in the U.S. and Canada in June after doctors discovered that she has breast cancer, and that it has metastasized to the sacrum, the triangular vertebra at the end of the spine.

This isn't the first time the best-selling recording artist has battled breast cancer. She was first diagnosed in 1992 and subsequently underwent a mastectomy.

ET spoke with Newton-John in 2005, who opened up about her health struggle, sharing, "Breast cancer is a very scary thing to go through and particularly in the first initial stages when you are first diagnosed because you don't know what that means. You don't know if it's spread anywhere else in your body. You don't know if you're gonna die. You don't know anything."

"I also was determined that I was gonna get through it, but I'd be lying if I said I didn't have fear and dread," she continued. "Of course I did."
