Why give high level radiation for microscopic positive margin
Im failing to understand this. My husband has hpv positive scc on his septum and it remained local. They were able to remove the cancer surgically and he was told there was a slight positive margin but the surgeon felt ut was negative but pathologist felt it was positive so they are recommending radiation as extra precaution but high levels going into his nose and front palate. The side effects and risks seem very high for possible microscopic positive margins. I jist don't want my husband to go thru possibly getting more cancer from radiation but I also understand the risks of it coming back. Can anyone help me understand this or had similar questions?
