The West Side Story star took to social media to share her experience with a breast cancer scare she faced when she was just 19.

"Two years ago I found a lump in my breast and went through what was undoubtedly the scariest week of my life," she wrote on her Instagram Stories on Sept. 24.

"No OB/GYN was taking new patients due to the backlog of the pandemic, but I was fortunate to have the care of my pediatrician who prescribed me an ultrasound.

Despite the serious situation, Rachel shared everything turned out okay and that the lump turned out to "thankfully" be benign.

Along with her message, the now-21-year-old shared a black-and-white photo of herself sporting the scar she was left with after the procedure. 

She said it "serves as a reminder to check my breasts regularly for any irregular growth."

"The fibroadenoma in my left breast is a common occurrence but nevertheless extremely scary to find," she continued.

Rachel's reveal comes six months after she shocked fans by claiming she did not receive an invitation to the Oscars ceremony.

"I will root for ‘West Side Story' from my couch and be proud of the work we so tirelessly did three years ago," she wrote on Instagram on March 20.
