I didn't know, Debby, but I looked it up and this is what I found:
"The tradition of the bell began at MD Anderson Cancer Center in 1996 when U.S. Navy Rear Admiral Irve Le Moyne, a patient, installed a brass bell at their radiation treatment center. The significance of “ringing the bell” caught on, and many cancer centers across the nation have also added this tradition. Several years ago Willmar Regional Cancer Center staff brought the thoughtful and caring action forward to their team. The decision was made to add their own bell to the Center as a positive way to celebrate the milestones in their patients’ lives.
“When a patient has completed their radiation or chemotherapy treatments, the joyous sound of that bell rings out,” said Lisa McBrian, RN and cancer care coordinator at WRCC. “It’s such a wonderful thing for everyone at the Cancer Center to hear though it may mean something different for every patient.”"
Thanks for looking that up Blooie!
For those still in treatment it may serve as that bright light in their future that they are working towards.
That's what I was thinking sour...the sound of the bell must give some hope they'll be able to do it too.
