I haven't done much research about stage 3, but my reasoning tells me that it depends on whether those suspected nodes were cancerous before chemo. If that was the case, I think your mom would be a Stage 3, NED. If those nodes were not cancerous, then it would either be Stage 1 or 2--again, depending on whether the shrinkage was a response to treatment or was due to imaging issues. Regardless, it's a great sign! Even if those nodes were indeed cancerous before, 0/38 means a complete pathological response, which is p e r f e c t!
Sending you and your mom hugs!
