grade 3 meningioma

Had surgery 6 weeks ago to remove grade 3 meningioma was told 2-3% remaining was offered 6 Weeks of radiotherapy 5 days a week reading a lot of information I came to the conclusion that it wasn't for me..the fact that the consensus is one size fits all and putting poison in a body to cover the area seems like sledge hammer to crack a nut or blanket bombing an area to kill one little mouse.

I'm vegan, healthy, on no medication am now getting into many antioxidant foods I'm a fit 69 yrs my question is if it comes back will I get chance of surgery? 

I go to bed early so am awake early 

Much regards
