Hyperhydrosis treatment with Botox after lymph node clearance?

I have treated people with Botox after lymph node clearance. There is no contraindication. However, it is always best to discuss any procedures, especially those that are cosmetic, with your oncologist too. "This answer has been solicited without seeing this patient and cannot
be held as true medical advice, but only opinion. Seek in-person
treatment with a trained medical professional for appropriate care."
