Gruesome Knitting Impalement Uncovers Lethal Threat

July 14, 2009 -- An unthinkable setback can be a blessing in disguise. No one knows that better than 58-year-old Ellin Klor. For her, a cosmic roll of the dice worked in wonderful ways.

On an otherwise normal Monday in January 2006, Klor joined her knitting club at a friend's house in Palo Alto, Calif.

"I was carrying the bag with the two needles in my right hand ... and tripped on the first step and sort of fell on my chest, on her porch," said Klor. "And I stood up and felt more or less OK, but I noticed that I had a pain in my chest whenever I took a breath."

Watch "20/20" FRIDAY at 10 p.m. ET to see Klor's story.

Klor picked up her bags and went inside her friend's home. Before long the pain in her chest became impossible to ignore.

"I put everything down and lifted up my sweater and my shirt and looked down and saw this broken knitting needle sticking out of my chest," Klor said. "And someone said, 'should we pull it out?' And I said, 'no, call 911.'"

That small decision may have saved Klor's life. Her doctor, Susan Brundage, said the needle pierced Klor's heart, and had she pulled the needle out of her chest, she may have bled to death.

"I asked her when she was outside the operating room, 'How did you know that?' said Brundage. "And she said, 'Well, I watch 'ER,' and on 'ER' they said never pull anything out that's stuck in your body.'"

Klor was rushed to Stanford University Hospital, where doctors worked on her for five hours. In an intricate operation, they removed the needle and sewed up Klor's heart. She had survived an incredibly random accident, it seemed.

But Klor's story doesn't end there. Ten days later, she got a call from the hospital, where a technician has been reviewing an X-ray from a follow-up test.

The news was devastating. The technician had discovered an enlarged lymph node on the right side of Klor's body. Soon, Klor was diagnosed with breast cancer.
