The day of her appointment, Molly prepared herself for the worst. "[The doctor] sat across from me and just was bawling," Molly says. "I remember thinking, 'My God, now what?'"

Then, the doctor broke some shocking news…Molly never had breast cancer. During testing, a medical technician accidentally switched her biopsy slide with another woman's sample. That woman had breast cancer but was mistakenly told she was cancer-free.

As the information started to sink in, Molly says things began to move in slow motion. "I just couldn't believe what was coming out of her mouth. Like: 'Wait a minute. I didn't have breast cancer?'" she says. "I was relieved because I thought: 'Okay, now I'll go back to my neck cancer, but what about that lady? What about the lady whose slide was switched with mine? Do you know who she is?' … The carpet's pulled out from under you, and you're just left there thinking, 'Now what?'"

Molly quickly began treating her neck cancer with chemotherapy and radiation, which had been postponed so doctors could focus on the breast cancer. Thankfully, the treatment was a success. She's been cancer-free for almost four years.
