Abby Lee Miller has returned to television as she continues to battle cancer.

The 52-year-old posted a photo to Instagram in which she is sitting in a wheelchair on set. The photo is found below.

The former "Dance Moms" reality star is in the midst of filming a documentary according to a source from E! News.

She captioned the Instagram post:

"Grrrrrrrr!!!! Back to the daily grind. Comment if you can guess what we’re shooting today? #abby #abbyleemiller #abbylee #dance #tvshow #dancemoms"

Miller smiled at the camera as she took the pic. A monitor is seen at the forefront, and a brown wall with the logo "Abby Lee Dance Company" is towards the back.

Miller is receiving treatment for Non-Hodgkin's lymphoma. She was diagnosed soon after her release from prison. She had been in federal prison for a year after she was convicted of bankruptcy fraud.

Prior to that, Miller quit the long-running show after its sixth season in 2017. Fans still believe she may return. Thus far, Lifetime has not commented on the matter.

Miller left the network on a distinct note. At the time, she stated that:

"For the past six years/seven seasons I have asked, begged, and even demanded creative credit for all the ideas, award-winning routines, themes and costuming -- to no avail!"

Following her diagnosis, Miller spent time in rehab undergoing chemotherapy and surgeries. She left just two months ago to live in her Los Angeles house.

Despite the star's grim diagnosis (doctors told her she might never be able to walk again), she is not giving up without a fight.

A source for People has described her as "getting a little stronger every day." And Miller seems to be holding onto that.

She continues to remain positive and is now soon to be back in the spotlight based on the Instagram post.
