Just got a call from the oncologist, who received the results from the hospital in Philadelphia.
It's more tumor.
It is still a favorable histology tumor, which means that there are no anaplastic features. But it's fast as heck, and it means that the chemo isn't doing the trick. After the surgery next week, in which they will remove the tumor from the right side, which was there in the first place, and remove the new tumor from the left side.
No changes will be made to The Boy's treatment regimen until the pathology comes back following the surgery, after which the plot will thicken.
