'Dance Moms' New Season Will Chronicle Abby Lee Miller's Cancer Battle

The newest season of "Dance Moms" is set to be its heaviest as the show will showcase the diagnosis, treatment and return of Abby Lee Miller while she wages war on cancer.

The sizzle trailer for "Dance Moms Resurrection" just dropped, and reveals a camera crew has been with Abby Lee Miller since she was released from prison and diagnosed with Burkitt lymphoma.

Fighting through pain and tears, Miller says, "I need to get back to teaching, need to get back to screaming at children." She works her way back into the dance studio to prepare a new crop of kids for competitive dance.

Miller makes it clear, "The ALDC is back ... watch out!"

"Dance Moms Resurrection" premieres in June.
