'Twinge'

According to reports, Bissonnette first noticed something was wrong with her when she felt a strange "twinge" while she was performing in 2019.

"I don't think we would have found [the tumor] if I worked a normal 9 to 5 job," she explained. "Because I move so much and I do crazy things for a living - I've been doing it since I was 5 - just [that] little moment in the show [made me go], 'Why am I having trouble today? There's got to be something else going on.'"

Bissonette acted quickly on her illness and had the tumor removed by February 2019, and underwent treatment, but despite her cancer, Bissonnette pushed through and performed, being there from the very first to the last performance on Broadway.

According to E News, Bissonnette is not only a Broadway performer, she is also a dance teacher and choreographer.

She studied at Point Park University under the Conservatory of the Performing Arts and has been quite successful in her craft.

She has had a hand in choreographing for the following theaters: The Munnt, Shakespeare Theatre Company, Seven Angels Theatre, and Riverside Theatre.
