Do I wait until after Christmas to start treatment

Hi everyone

I have just been diagnosed with T3B gleason 4+4 And have a PSA of 87. No mets and no node activity.

Seeing consultant on Friday and expect she will want to put me on hormone therapy immediately followed by prostatectomy.

I want to enjoy Christmas with my family. Is there any harm in maybe  allowing myself that luxury or in your opinion do I just get on with it and suffer the side effects immediately  regardless of wanting to spend  a decent Christmas with my family ? In other words .... do I even have that luxury?

Any comments would be greatly appreciated to help me make the right decisions

Many thanks
