20 years and still "dancing"

I wear a ballerina charm on my bracelet. Only did tap dance at age 5, but seemed appropriate. Out of curiousity I looked up appropriate symbol for 20 years (silver is 25, etc). Platinum is 20 years. Platinum is far more expensive than gold for 50 and no way could I afford that. But I found platinum coated sterling silver rings that are beautiful AND inexpensive. So I treated myself.  I had never celebrated a milestone before.  In addition, have gone so far as to have (had, I hope) mets to my adrenaline gland. But my tumor markers have been in the normal range for the last 4 months. I ask my onc do I dare think that all is now gone. She replied that my bc has certainly been quiet for a few months. Quiet I will take!
