How do you apply bolus and confirm daily air gaps/setup for vulvar cancer, especially for larger, fungating lesions?  

For me, I am into "wet cotton gauze" wrapped in (new) plastic wrapping daily....for it is more conformal than even the old paraffin wax molds I used to use back in the day. Clearly, it is at best a 'guess-ti-mate' as to the thickness required for each case. But it does and has worked...
