Olivia Newton-John announced yesterday that she has breast cancer and is canceling her June tour.
The 68-year-old said she initially thought she was suffering from back pain, but learned it was "breast cancer that has metastasized to the sacrum."
Olivia said she will go through "a short course of photon radiation therapy" and hopes to perform later this year.
Ticket buyers will be refunded for the canceled shows.
