How has Serum Her2 test worked for you??

[alw]

Hello,

For those of you using the HER2 Serum Test to monitor disease, what would be (or has been) your course of action should the number begin to rise? and also, how often are you having the test performed?

My sister's oncologist has said that the test is too new to dictate treatment changes. I'm wondering if anyone else has come across this type of attitude?

And how is your treatment impacted by any changes in the test results?

Regards,

Amy
