Radiotherapy or not?

Hi everyone 

I am 8 weeks post reconstruction surgery for ACC of palate (T1). Got the all clear from histology but advised to see oncologist by the surgeon because at a previous operation 3 months ago (when they thought my tumour was benign) there was evidence of peri neural invasion. Which is why I went on to have reconstruction.

I am waiting to see oncologist but my feelings are if my recent surgery shows no spread and all clear why have radiotherapy?? If ACC tends to return in the future (so I’ve read) surely it’s better to keep the radiotherapy treatment for when and if the cancer recurs especially if it is graded higher or has metastasised ??? 

I’ve read such a lot about ACC, it seems fairly standard that everyone has radiotherapy just wondered what people think and if anyone has had a similar experience??
