Herceptin and CA 27.29 tumor marker

[Cal-Gal]

Hi Weety,

So sorry you are going through this worry--

You can see since my initial worry in April that the following month the marker went down almost 6 points--it seems mine like yours tend to bounce around that same area.

I finished Herceptin about 6 weeks ago--and funny you should ask about this now--I was freaked out only about a week ago-after being off the Herceptin about 5 weeks, my marker jumped to 42.2--the Onc had me retest 2 days later and it was back within normal range--but still at 34---

I have read that the 38 normal set point is just that a set point and that some Onc's think it should be lower.

All I know is that if mine is within normal my Onc doesnt freak out--

As for ME--I am just making sure that I am diligent about reporting pains etc-and making sure I have all my scans on time!!

Don't know if we can do anything else?

Good luck--Hugs,
