Cancer-Stricken Abby Lee Miller Gives Fans New 'Horrible' Health Update

Ill Abby Lee Miller has been sharing her battle with cancer with fans—and on Saturday, she revealed how serious her treatment has been following her cancer surgery.

The former Dance Moms teacher wrote on Instagram, with a photo celebrating the recent end of her prison sentence, "Now I have to handle the aftermath/ treatment/ physical rehabilitation of 10 hour emergency spine surgery to remove a mass from strangling my spinal cord and the horrible severity of what that mass turned out to be!"

Miller, 51, spent eight and a half months in prison after pleading guilty to not reporting an international monetary transaction and one count of concealing bankruptcy assets.

RadarOnline.com exclusively revealed on March 27 that the former Dance Moms star had been transferred from Victorville federal prison to a halfway house in Van Nuys, California. But just days later, Miller's medical crisis began!

On April 17, Miller went into surgery for a multi-level laminectomy after she experienced "excruciating neck pain" and weakness in her arm.

She was ultimately diagnosed with Burkitt lymphoma, a rare and fast-growing cancer that affects the lymph nodes.

Since then, Miller, who was disgraced by her financial misdeeds, has been getting her business affairs, will and funeral plans in order, according to a RadarOnline.com insider.

Now Miller, who didn't have to complete her prison sentence in the halfway house after her hospitalization, is free of legal woes.
