Jen O'Shea, Cancer Survivor, Can Turn Her Leg 180 Degrees (VIDEO)

Cancer treatment gave Jen O'Shea a very surprising talent. The Toronto woman can turn her leg 180 degrees so that the bottom of her foot faces the ceiling.

O'Shea was diagnosed with Ewing's sarcoma, a rare form of bone cancer, in 2010, and had to get an internal hemipelvectomy in 2011. In short, doctors had to remove the right side of her pelvis and didn't replace it with anything. The 28-year-old Torontonian had to go through months of physio just to do basic tasks like climbing the stairs without crutches or walking. But about a year ago, O'Shea and a co-worker discovered that the surgery gave her a weird ability.

"I slowly lifted it up and I freaked out and he freaked out and we were at work so a co-worker comes by to see what's going on and they freaked out," she told the Sydney Morning Herald.

O'Shea says that turning her leg like that doesn't actually hurt and she doesn't even feel much stretching. "My mom was very adamant that she didn’t want me to do it. She was very worried that I was ruining the procedure," O'Shea told the Huffington Post Canada over the phone.

She asked her doctor, who didn't think it was harmful either. "I showed my physiotherapist and she thought it was so cool and she was fascinated by it. But she was baffled," O'Shea explained.

O'Shea kept the ability quiet but the Ellen Degeneres show's recent "Here's My Talent" contest urged her to reveal her ability and she recorded herself bending her leg and people's reaction to it.

In the video you can see Jen's friends shocked by her ability. "That is so gross," one girl can be heard saying, half-laughing. "What in the hell?," an older gentleman can be heard saying before he proceeds to tickle O'Shea's feet. The video, posted May 13, already has more than 380,000 views. Unfortunately O'Shea didn't get on Ellen but with the attention her video is getting, the talk show host might be reaching out to her.

O'Shea has also been recording her recovery from surgery. Something she says she did to reassure her parents who live out-of-town and to show her friends who may not understand what she was going through. She hopes it also has the added benefit of showing other patients what to expect.

"There was almost no documentation on right internal hemipelvectomy," she said.

"I thought it would be great if you could help one or two people in the future who have to go through this," she added.

"I’ve received messages from other patients who say thanks, it gives me hope. They’ve appreciated that they can see what’s possible," she said.
