Once again, the Tree of Hope Lighting lit up the night sky at Kaminski Park at Roswell Park Comprehensive Cancer Center. 

From 4:30 p.m. until 6:30 p.m., families and friends enjoyed a dazzling display of nearly 75,000 animated lights orchestrated to music along with fun activities including the Gingerbread House Contest and raffle, a festive horse-drawn carriage ride, sips of hot chocolate and visits with Santa & Mrs. Clause!

During the annual holiday tradition, we told stories of how treatment at Roswell Park has offered hope to those touched by cancer, even those who live beyond our borders.

We also provided an update on the SurVaxM clinical trials that are showing some promising results.

Before the lighting of the Tree of Hope, we took a moment to honor all of those touched by cancer during a candle-lighting ceremony.
