A 5-year-old cancer survivor from Westchester is hoping to serve as an inspiration for other kids.

Cassidy Kline, of Larchmont, was only 3 years old when she underwent 15 months of intense chemotherapy to fight back against a sarcoma that started as a bump on her arm.

"She woke up in the middle of the night with pain and a hard lump on her left arm, and we weren't sure what happened," says Janine Kline, Cassidy's mother. "Three weeks later, after a biopsy and several tests, they told us that she had cancer. Stage 4 rhabdomyosarcoma. So, it went from taking her to a follow up doctor appointment to being hospitalized for three weeks. "

In September 2019, Cassidy along with her family were granted the news they'd been hoping for—after nearly a year and half, Cassidy was finally cancer-free.

"We had the appointment and they said, 'You can actually say that Cassidy is cancer free for her 4th birthday,'" says Kline. "I didn't realize that I had been holding my breath that entire time until that moment."

Cassidy and her family are partnering with Stop and Shop as part of the company's 20th annual Help Cure Childhood Cancer campaign. It allows customers to donate for pediatric cancer research at Memorial Sloan Kettering Hospital.

"We're able to see many of the children who are able to benefit and are survivors of the cancers that they've been diagnosed with because of the funding that Stop & Shop has provided from the generous donations from their customers," says Maura O'Brien, the manager of Community Relations at Stop and Shop.

Stop & Shop has raised more than $25 million for pediatric cancer research over the last two decades. Donations can be made during checkout at your local Stop & Shop or online.
