Hi there @Michaela When I was first diagnosed with BC in 2006 radiation therapy was recommended. There was no public service where I live and the provider would only give an estimate of costs -- about 10k.
I didn't have the money, being a single mum, and the only local provider suggested I sell my house if that was the only way I could afford the treatment. I told them to bugger off and I'd take my chances. In was already broke, and I couldn't see how don't homeless would help. At least the house was insured and I had a bit of super which would give my dependent son half a chance. That was a shit position to be in, but was common enough at the time.
My cancer came back in 2016 but by then there was public radiotherapy here, even if I had to travel 100 km each way for it. I don't regret doing that.
To be honest, rads is a doddle compared to surgery and chemo. None of this is fun and I ended up with some nasty burns, but they only lasted a fortnight. Which is a pretty small price to pay.
Throw everything at it if you can. Mxx
