The same thing happpened to me. My doctor doesn't thing scans are necessary and I really need to know if there is any cancer left in my body. I live in Australia and I assume that the Australian government does not cover the cost for these scans. I assume that's why GP's are not allowed to write referrals. I was also denied to have blood tests (tumour markers). I offered to pay for it from my own pocket but it was still rejected. Now I am looking for help abroad.
