Tumor Marker Ca 27 29

[HavahJ]

I have been reading this board for a long time, but I just got enough courage to register. I'm climbing the walls about the ca 27 29. I have IIA, which is a new contralateral tumor after 13 years. I had mastectomy, all the chemo and 1 year of herceptin that ended in August. The tumor was small, 1 node ER/PR pos, her 3+. I also have a complicating factor of multiple sclerosis! That's the short short story. Anyway, since herceptin I've had 3 ca27/29. The first was 13, then 17, then 25. I can't get retested until next week and being alone here, all I do is cry and worry that it must mean I have a recurrence. Can anyone else tell me their experiences with CA27/29? Hearing other peoples' experience is the only thin that calms me down. Thank you P.S. Does anyone know if having a flu shot right before the test would change anything?
