Abby Lee Miller has been giving us many health updates via Instagram lately. But her newest one is making her fans especially worried.

On Tuesday night, the 51-year-old Dance Moms star, who was diagnosed with a form of non-Hodgkin's lymphoma called Burkitt lymphoma in April, revealed on Instagram that she recently underwent an "emergency surgery" and is now on the mend.

Miller's announcement comes just a few days after she celebrated being released from jail on May 25 for bankruptcy fraud.

"After another 2 hour MRI this morning, the pros thought I needed one more quick little emergency surgery! Ugh!," Miller wrote on her newest post. "I'm in recovery now and texting so everything must be okay, just hiccups in my plans!"

She finished her caption with a shoutout to her fans for being so supportive through her difficult journey.

"I'm on a tight schedule, shooting two projects and I need to get out of here and on with my life! Please keep me in your prayers. I'm grateful for all the well wishes!"

Despite Miller's reassurance that everything is okay after the "emergency surgery," her Instagram followers understandably began voicing their concerns for the reality star.

"Hope all is okay Abby ❤️❤️🙏," chloeculligan said. Meanwhile, user matosmanny seemed worried that she was focusing too much on her endeavors instead of getting better. "Projects can wait. Your health comes first. Sending lots of love and healing prayers from Tampa," he wrote.

According to another Instagram post four days ago, Miller recently began another round of chemotherapy.

"I should be planning a weekend of fun in the sun at the pool," she captioned alongside a throwback photo on Instagram. "There’s nothing I enjoy more than swimming and a good tan! Instead, I start round 3 of chemo ……… another battle that I must win!!!”

At the end of May, People reported that she still may have even more chemotherapy to go.
