Hi All
This is Kathy from BCNA's Policy Team. I just wanted to jump into the conversation to confirm that, in Australia, tumour marker tests are really only used in women with secondary breast cancer. They are used to help doctors (usually medical oncologists) determine whether or not the cancer is responding to treatment. But as Amy said above, they are just one of the things the medical oncologists take into consideration.
There is an article about tumour markers in Issue 21 of The Inside Story, which is BCNA's supplement to The Beacon for women with secondary breast cancer.
Hope this helps.
Kathy
