“I just finished my 5th round of Chemo!!!” Miller proudly announced alongside a photo of herself putting on some mascara. “I think I deserve a little treat today, so I’m putting on my make-up just in case! #abbyleemiller #aldcla #abbylee #dancemoms #aldc.”

"She’s been very positive through the experience," ET's source revealed on Monday. "Considering what she is going through, she is doing really well. She’s ready to get back at it in her life."

"She has a good prognosis. Her future is very promising," the source added. "This is a bump in the road. She'll come back stronger than ever after this.She is going to be amazing. She’ll always dance and teach dance, that’s just who she is."
