Abby Lee Miller may never walk again.

The former 'Dance Moms' star - who is currently battling Burkitt Lymphoma, a rare form of cancer - has been told by doctors that her prognosis is looking ''bleak'' but she's not letting it affect her as she's determined to dance again.

A source told E! News: ''Her prognosis is bleak, but she is vowing to beat this and not only walk, but dance again. She has been open about her diagnosis with her close friends who are in awe of Abby Lee's fighting spirit. Her inner circle is rallying around her with support and regular visits to the 'Dance Moms' star.''

Abby's cancer battle has been documented on camera and she has agreed to release a special show to raise awareness and share her heartbreaking journey.

The insider explained: ''This entire situation is being documented on camera and will be a focal point on Abby Lee's upcoming televised cancer special.''

The 51-year-old star first underwent emergency surgery in April after complaining of ''excruciating neck pain''.

She went under the knife for a laminectomy, an operation to remove the back of one or more vertebrae, and her doctor, Dr. Hooman M. Melamed, previously admitted the dance instructor would have died if she had not had the procedure.

He said at the time: ''She's made some recovery in 24 hours, which is better than no recovery.

''Nobody wants to end up thinking they're going to be paralysed for the rest of their life. That's a reality that's facing all of these patients going into it. All you can do is pray and, as a surgeon, you maximize everything you can for the spinal cord to recover itself. I am hopeful.

''There's a chance this can spread to any part of the body ... this is probably coming from somewhere else.

''We don't know where the source is. Any tumour that spreads anywhere is automatically Stage 4, but we have not determined the stage yet.''
