In April, she had emergency surgery after what was believed to have had an infection in her spine.

And nearly five months after her procedure, Abby Lee Miller, 51, has reportedly left rehab, according to Us Weekly.

The Dance Moms star made the decision to exit in order to cut costs, despite struggling to walk.

'She isn't doing good. She left because it's too expensive to stay in rehab,' a source told the site.

'She's home, she can't go anywhere else. She still can't walk. It's really sad.'

Abby's choice to undergo the surgery was done in order to prevent paralysis.

The day following her operation, Abby was diagnosed with non-Hodgkin's lymphoma.

What was originally thought to be an infection turned out to be cancer, her doctor told People back in April.

'It was not an infection, it was a type of a non-Hodgkin's lymphoma...'

She has since been receiving chemotherapy to treat the disease, and has documented her progress on Instagram.

Last week, the Pittsburgh native shared a snap of herself with two occupational therapists.

'I still beat them! On foot they failed & their birds flew too slow! Seriously, these two female Doctors, @kadeletti and @missoscar22 were such vital parts of my Physical Rehabilitation - I can never thank them enough!,' she said.

Despite her struggle, Abby has done her best to remain strong, and has received support from her former dance students, including Jojo Siwa.

'Abby is doing great. She's in good spirits, she has great people surrounding her,' the Youtube star told Us. [She still] 'has a couple of rounds of chemo to go through.'
