Same happened to me, I was in shock after I saw the drawings on my hands. I thought I just had one nodule and small cord on the right hand and about 5 flat nodules growing on the left. Not so, my drawings on my hands were almost the same as yours. I know I made the right decision. Still, no progression on either hand. (First round of RT was in Sept., second in December).
Nodule on right hand, was very big, is almost gone. Still have the cord, but who cares, it does not bother me.

Best of luck with the treatment.
