Through tears, Miller pulled herself up and used a walker to take a few steps, as the audience cheered her on.
"This is scary, you have no idea," she said.
She shared a clip of the moment on Instagram, writing in part, "Watching this made me cry!"
Watching this made me cry! Thank you @thedoctorstv for letting me share my story with the world! Dr Lawrence Piro, Dr Hooman Mellomed, Dr Christopher Boudakian, Dr Simoni for your wisdom and kindness. My PT was so amazing, CRI is the best! I’m not nearly as strong as I was during this taping. I have a long way to go - if there’s 1 thing I know, it’s that I’m a fighter and there’s no such thing as “can’t”! . . . . . #thebestisyettocome #aldcla #aldcstrong #aldc #abbylee #abbyleemiller #cancer #lymphoma ##theangelesclinic #thespinepro
Miller was diagnosed with cancer last year and had to undergo emergency spine surgery to remove a tumor wrapped around it. All that came while she served eight months behind bars for bankruptcy fraud.
Just three weeks ago, Inside Edition's cameras tagged along while Miller had knee replacement surgery. Check out the video above to see more.
