i had a similar procedure--robotic removal of primary BOT and modified neck dissection to remove lymph node may 10 2013---my margins were clear and only one node had cancer and no extracapsulary extension---nonetheless radiation was recommended---i finished rads on august 7 ---worked full time as lawyer for all but last week of radiation and two weeks thereafter---checkup every 3 months and cancer free for 6 months now--some lingering dry mouth and taste issues from rads otherwise back to normal--i decided on radiation because i am otherwise healthy and wanted to fight when i was strong--don't let employment drive your decision--there are always jobs--good luck
