Hi Tanya, thanks for your response. Yes I knew that some sort of test existed and had tried on more than one occasion to investigate it with my medical team but had no luck. You reminding me of the test made me take up the task of digging further and I eventually found out that the name of the test is Tamoxifen PredictAR! From what I can see, it hasn't been available in Australia for very long and is not on the PBS list like you said. I went to see my GP today and he was very supportive of me getting the test done which was wonderful news! I am going to find out a bit more about it first, including the cost, via a customer helpline that the testing company has.
So thanks once again Tanya for giving me the encouragement to continue pursuing this. It just goes to show that at times we need to be very assertive, determined and persistent when it comes to our health....and like the old saying goes "there's more than one way to skin a cat!"
