Tumor Markers make me wonder

[Gift]

My tumor marker CA 153 before the operation was 13.8. It dropped to 11.3 afterward.
Just had the result of CEA today and it's still in range 3.850 ng/mL (0.000 - 4.700)

I am wondering if these tumor makers show anything, whether they sound.

dx July 2010 with ER 80% PR - Her2 +++ 7 cm lumph
3 rounds AC (stop after round 3 since the tumor didn't shrink)
3 rounds Herceptin until tumor gets smaller to 4 cm
Lumpectomy on 12 Dec 2010
Still on with TCH x 6, and continue Herceptin to one year

Gift,

Here's a website about the tumor markers:

I've never been given a tumor marker test. My oncologist does not think they are reliable measures for my diagnosis and treatment.

It looks like your tumor responds well to Herceptin. That is great! Please keep us posted.
