My unit doesn't have a bell. So I have bought them one...just need to get a plaque done with the poem. After all the endurance of treatment I don't think you can underestimate the importance of ringing that end of treatment bell. My last chemo was such an anticlimax, I baked a cake...and they just cut it up out the back...I'd planned to cut it myself as the celebration . ..but I guess unless you've been through it...you just can't appreciate it. Even though I'm still on herceptin...the completion of each part is significant. Well done you . ..you're an inspiration...and such an incredible birthday present.
