My son did not have chemo or amputation, he had radiation followed by surgery, but our story along with everyone's here is so unique and complex. From all the stories here, It depends so much on where the tumor is as to what course of treatment is recommended, what is crucial is they have to be able to get it all out as the spread is so likely and SS can come back after such a long time. The doc needs to explain the reasons for his choice to you in a way that makes sense, ask lots of questions. Amputation may seem harsh because your precious son is so young, but SS is way scarier. There are many positive amputation stories here. The one thing I do know is that the decision you make will be the right one, and you have to know that and believe in that with all your heart and soul. Wishing you strength & sending lots of love.
