one. Going to move to our "Gma" cover story. "Dance moms" star Abby Lee Miller out of prison about to make her return to TV and talked to Paula Faris about surviving a difficult health battle behind So Abby Lee beat cancer, been through a lot. When I asked her how prison changed her she says, you don't want to know but then she detailed how she was threatened and mistreated during her time behind bars. Sloppy. Get up in the air. Reporter: This morning the hard-charging larger than life "Dance moms" star Abby Lee Miller. Everybody is watching you cry. Save your tears for the pillow. Reporter: Getting candid about her eight months in prison proper bankruptcy fraud. How does it change you. It's a joke. Wouldn't I have done better teaching underprivileged children to dance or just working, you know, fine me. Whatever. It's absolutely asinine. The entire thing? Are you treated any different because you are a quote/unquote celebrity. I was by the guard, by the prison system absolutely. Did you ever feel threatened in prison. Only by the staff, by the guards. I was --S where's that dance lady. Where is that TV star lady. We're going to get her. They said -- They come into your room and take your locker, they dump everything out of it. They take red soda pop and shake it up and spray it over your clothes. When a man or somebody, a woman, in power screams the "F" word at you over and over again, to me that's offensive. That's violent to me. And that went on a lot. Trying to pull my eyelashes off that were extensions. They were pulling your eyelashes off. Yes, the first day I went in and she kicked my bed and she screamed at me. Reporter: The federal bureau of prisons would not comment specifically on Miller's allegations citing inmate privacy but in a statement to ABC news said that it provides, quote, a safe, secure and humane environment for staff and inmates adding that if there are allegations of misconduct, they are taken seriously and when appropriate referred for proper investigation. Miller meantime, reflecting on her time behind bars, by offering advice for actsses Lori Loughlin and felicity Huffman who are both facing possible prison time for their alleged involvement in a college admissions scandal "Varsity blues," Loughlin has pleaded not guilty in the case. What should they expect if they have to do prison time? The girls in prison are going to be fans. They want to know what it's like to live with a movie star or, you know, a television star. They want to know about your case. Everybody in there, every single woman that I came in contact with just wants to tell their story. I don't know those two ladies personally but from their television personas, I don't think they would have the same issues that I had. Okay. Because, you know, everybody knows me as being tough and mean and yelling at little kid. After leaving prison Miller was ready to start a new life but then another setback. She was diagnosed with Burkett lymphoma discovered raf an emergency back surgery. What would have happened had they said go home. I would have been dead ten minutes. You were that close to dying. That close to dying. I was paralyzed from the neck down. No movement because this cancer, this lymphoma was choking my spinal cord. Miller endured ten rounds of chemo and two surgeries. She still can't walk. Do the doctors anticipate that you'll be able to walk again Jo. Yes, right now the biggest issue is my right knee. I have needed a knee replacement for about seven years now. When do you want to walk again. Right now, today. What does that say about you that you beat this strong cancer? Well, I'm tough and, you know, I firmly believe that all the world is a stage and we are merely the players so I think this was all destiny. It was supposed to happen this way and it did and I'm just following the script. One word to describe how different you are? More appreciative. Thankful. Reporter: Now 52, Miller is getting back to what she does best. I've been given a second chance. Will this team have what it takes to carry on my legacy? Reporter: Returning to the spotlight for season 8 of "Dance moms," the show that made her famous. At the end of the day I'm a teacher. It's what I do. Just needs to be bigger, bigger, bigger than life for the internet. What are these kids in for? The ride of their lives. You're notoriously tough on these kids. Do you ever regret going tore? Never. Never? Never. You survived prison. You beat cancer. How does that change who you are, Abby? It doesn't change me. I've always been a fighter. For every mistake I've had to come back stronger, tougher, better. So I asked who is tougher, the prison guards or these unreasonable dance moms she has to deal with and she said without hesitation, the prison guards were tougher. I thought you were going to say the other. Well, it's kind of a toss-up but season 8 premieres on lifetime in early June and looking forward to creating some other shows and hopefully gets to pitch those in the near future. To ginger.
