A sister of Heather Farr has breast cancer, the same disease that killed the golfer in 1993.
"I've known about it for five days, and I'm in shock," Missy Farr-Kaye said. "The minute I found out, I thought of Heather and what she went through.
"It's very surreal, like a really bad movie. I feel like I'm talking about someone else, like it was Heather's disease. That it's gotten me, too, is devastating."
Farr-Kaye, 30, has two sons, Dalton, 4, and Riley, 7 months. Her surgeon, Dr. Raymond Shamos, said he is "hopeful of a total cure."
Heather Farr died at 28 after battling cancer for four years.
Farr-Kaye won the 1982 Arizona state high school championship as a sophomore. She was all-Pac-10 at Arizona State.
