[kat in the delta]

I go to my Onc. tomorrow to see the results of my hormone levels---which I am sure I will be post menop. I had my uterus removed 6 yrs ago, but kept my ovaries. He mentioned either Arimidex or Femara, which my sister took and it make her jts/ ache/ Her Onc changed her to Aromasin and she says it is better altho she liked tamoxifen the best---but was on it for 5 yrs. She was not her2. like me. kat
Is there anything I need to know or ask him about before my visit ???? I just finished my only year on herceptin, but see another study of 2 yrs. What is the difference between the Bayer Serum test and the serum blood test/?, elissa(sp?) blood test etc,,,,,,kat
