The "Dance Moms" star attempted to walk for the first time, on Tuesday's episode of "The Doctors," since she was paralyzed and confined to a wheelchair after being diagnosed with Burkitt Lymphoma in April 2018.
However, the specialist claimed the cancer has a "10 to 20%" chance of returning, which gave Miller pause.
"I'm thrilled, and I know I'm supposed to be overjoyed, but I didn't know that Burkitt Lymphoma could even come back… I thought Burkitt Lymphoma, I thought once we killed it, it was done. Maybe I was just lying to myself and not wanting to believe that it could ever come back."
"It is a very curable thing, but it does have a relapse rate. The first year is the most important time. We need to survey it very closely," Piro reassured her.
A defiant Miller quipped "It's not coming back because I don't have time."
The Pittsburgh native, who recently served time for bankruptcy fraud, was diagnosed with cancer last year after undergoing several spinal surgeries to remove an infection.
But now with the news of remission, Miller can enjoy the next chapter of her life with her family and friends, including JoJo Siwa. The internet sensation surprised Miller with a pre-taped video message during the episode of "The Doctors".
"You are seriously one of my favorite people ever… and the time we worked together on 'Dance Moms' was the time of my life. You are so awesome, I love you so much. And forever."
