Abby Lee Miller reflects on painful cancer battle as she marks four years since becoming paralyzed from 'the neck down'

Abby Lee Miller reflected on her challenging battle with a rare form of cancer, Burkitt lymphoma, as she marked the four year anniversary of not being able to walk again after becoming paralyzed from the neck down. 

The 56-year-old Dance Moms shared tragic photos on Instagram from the last time she walked to the doctors office, and described the immense pain she felt while her body was breaking down. 

'Today, April 13 is the Anniversary of the last time I WALKED,' she wrote. 'In horrific pain, I made it into a Doctor's office and then across the street to a hospital for a sedated MRI. 

'On Friday the 13th, 2018 techs had to remove me from the imaging machine after 15 minutes because my arms & legs were flailing about uncontrollably! My health declined rapidly. 

Miller noted that she was then admitted to the hospital and 'then ignored' by medical staff. 

'Over the next 24 hours my blood pressure dropped to 23 over 17, my Kidneys started to fail, and I became paralyzed from the Neck down,' she wrote. 'It was too late to transfer me. Emergency surgery had to be performed.

She added: 'I have never walked on my own again.' 

Miller wrote that she's filming the final footage on a documentary about her journey and thanked all of her fans for their continued prayers and support.   

Abby Lee has since used a wheelchair for mobility after being diagnosed with the  rare form of non-Hodgkin's lymphoma. Her diagnosis came after the surgery, which was initially believed to be a spinal infection.

In 2019, Miller revealed that she was cancer-free, and told PEOPLE at the time that she's 'more than grateful' for her health.

'I was always grateful but I think I must say 'Thank you' a hundred times a day because I have to rely on strangers; someone to open the door, someone to get the hanger off the rack at the department store, someone to pick up my phone if I drop it,' she said. 'How am I supposed to get it? I'm very grateful and thankful to strangers that have been so kind.' 

She had a heart to heart with Jada Pinkett Smith at the grand opening of Debbie Allen Dance Academy at the Rhimes Performing Arts Center in Los Angeles last weekend, where they talked about hair loss.

'I had a chance to talk to the radiant @jadapinkettsmith and we both agree - it's just easier to throw on a baseball cap than it is [to] do your hair!' she wrote.

'Whether you lose it all going through rounds of chemotherapy (like I did) or as a result of many other illnesses, functional disorders, too much wear and tear, even a hereditary disposition - you can always be beautiful inside & out!' 

In 2017, Abby was indicted on 20 counts of fraud and was sentenced to one year and one day in federal prison. She was also ordered to pay fines of $40,000 and $120,000.
