I recently went to the doctor and found out my tumor marking went from a 16 to 69 in one month!!!! I had a bilateral mastectomy ( two years ago), complete hysterectomy, monthly zometa for one year, Arimidex for one year, and started faslodex four months ago. I will be getting a PET scan done next month. I was wondering what it means when the tumor markers go up? My doctor told me not to be worried!!!!! But I AM!!!! Need some help!!!!


It's so hard not to panic!
The numbers themselves are not entirely definitive. According to my oncologist, what your doc and you should look for are trends upward or downward. Some women, like myself, never have TM's greater than 70 even when we have full blown acceleration of the cancer, while other women see their markers go up into the hundreds when they are just starting to have problems. It really varies a lot from person to person. So what you probably need to focus on is what your TM history looked like when the cancer was flaring up and also whether or not your next TM number continues to show an upward trend.
If you feel uncomfortable with waiting, ask if your PET scan can be moved up a few weeks. Ask your doctor to explain to you why you should not be worried by the number. If he has a valid reason, he should be willing to explain it to you. Also, listen to your body. If you are not having new symptoms or pain, then perhaps it is just a 'blip' in the numbers. Try to stay positive, but advocate for yourself and ask questions until you get answers you understand.
All of this is easier said than done, but keep trying to control the fear :) My thoughts and prayers are with you!
