Good on you @Della - great that you've made your decision .... usually they wait until the surgery site has totally healed as they don't like doing it on wounds that haven' healed ....
I had my surgery in Mid Jan & then had rads in the 4 weeks leading up to Easter - so mine was a good couple of months+ after the surgery. I had a holiday booked to Norfolk Island after Easter & my Rad Onc had even said I could wait til AFTER the hols if I wanted to ... but I preferred getting it done before the hols, so I could relax & enjoy it, not 'pondering' the rads! It was my 'well done you' pressie to myself for going thru it all! xx
I went private for my surgery (about $8000 out of pocket all up) & public for my rads (I didn't have to pay a penny) & as I am rural, IPTAAS also paid for my fuel. As the treatment is every day, Mon-Fri, I stayed at the local "Rotary Lodge'' that was on the hospital grounds & just had to walk over to the Cancer Centre. It was incredibly convenient, otherwise it was a 2hr (each way) trip, every day.
Take care & all the best - I hope you get a Rads date soon. Most find their Rads fairly 'easy' compared to what we 'think it is going to be' - just make sure you let your Nurses know if there is any extreme redness or skin breakdown .... and keep applying the moisturisers that they recommend at least twice daily after each treatment. (They don't like it being applied on the day BEFORE the treatment, but is fine afterwards.). They'll take you thru all the procedures. xx
