Students at Billerica Memorial High School are giving up their cellphones for three weeks to raise money for those affected by cancer.

The "Celling Out for a Cause" event started two years ago when the school’s hockey team gave up their phones to raise money for a local boy with leukemia. The team ended up donating $75,000 to Ian Cadden, who is now cancer-free and a freshman on the school’s junior varsity hockey team.

More than 50 students and staff members turned their phones in to Billerica Police, who will lock the phones away for three weeks. Since helping Ian, the school has chosen a different family affected by cancer to help each year.

"I just think the sacrifice of giving up a phone is nothing compared to cancer," said Kayla Foye, who gave up her phone.

About 10 percent of the money raised will also be donated to the Dana Farber Cancer Institute.
