Hmmmmmmmmm...higher rate?
Terri,
I certainly do not have an answer on Her2 rate associated with DCIS or
less with IDC....
But, when I had my mammogram the first words from my dr. was it was
so small that they were very positive it was DCIS...also the breast surgeon told me that currently DCIS is now being treated as a cancer.
Yes, it is a pre-cancer...and it would be staged at 0 it really means
that the cancer has not become invasive. As small as my tumor was
a portion of it had become or was...invasive. DCIS still requires treatment.
Also one is at a higher risk when being dx. with DCIS for the cancer to come back, therefore, treatment is advisable. Lumpectomy, radiation.
There are different grades of DCIS...maybe that is where the Her2 rate
may show more information (I do not know)....I would gather that Her2
is not in all DCIS but would be judged by the personality of the DCIS.
I do know of any studies done on DCIS rates with Her2.
