Sherril was living in Delray Beach, Florida when she was diagnosed with breast cancer in 2018.  She went through treatment in Florida, including a mastectomy.

Having grown up in Massachusetts, and the daughter of Bruins Hall of Fame goalie Gerry Cheevers, Cheryl was very familiar with Dana-Farber.

Cheryl decided to go for a second opinion with Dr. Erica Mayer at Dana-Farber's Susan F. Smith Center for Women's Cancers following her treatment in Florida, just to make sure everything was on the right track.

 She was just finishing up a telehealth consult when she told Dr. Mayer that she thought she felt a swollen lymph node.

 That revelation set off alarm bells for Dr. Mayer and Cheryl was subsequently diagnosed with a different type of breast cancer in March 2020 at the start of the COVID pandemic shutdown.

Her treatment included chemotherapy, radiation, surgery and targeted therapy for her specific type of cancer.

Because patients could not have visitors with them during the shutdown, Cheryl took money she raised from a golf tournament to help pay for little gift baskets for other patients at Dana-Farber to help boost their spirits during this difficult time.
