Hi @Pamella you've had some good suggestions there to think about. Can I suggest a couple of other resources? There is a molecular test available under certain circumstances to help clarify if the addition of chemotherapy to radiotherapy and homone blocking therapy will provide additional benefit. The cost of the test is around $4000 and is not covered by Medicare. it may be worth asking your oncologist if your situation makes you eligible for the test. Here is the link for more information:

If you would like to talk through your choice with someone, don't hesitate to contact the BCNA Helpline on 1800 500 258 Mon-Fri 9m-5pm EST.
