Only a crystal ball!  It is rather like asking on which road you are
going to get hit by a bus.  It's not the women who are ER+ or HER2+,
these are characteristics of the particular mutations that occurred to
cause the particular cancer.

There is no single test that can a.ses the overall risk factor for any
cancer.  All you can do is examine all the major risk factors (genetic
markers, family history, race, BMI, etc) and if one or a combination
suggests you are at unusual risk, then take appropriate action such as
avoiding estrogen in foods or medications or from obesity.

I don't think your particular cancer necessarily indicates much of an
increased risk for your daughter - as your risk was elevated by the use
of HRT (although of course the risk was not known at the time), then the
fact that you got it is not so indicative of a genetic predisposition as
it otherwise would be.  If *your* mother or sister also had bc, then
that would be more significant.

Web sites that might help you: on general risk factors,
  www.imaginis.com/breasthealth/bc_risks.asp
and on the oral contraceptives link in particular
  www.cancer.gov/cancertopics/factsheet/Risk/oral-contraceptives

In general try a Google query structured like
  "breast cancer" "oral contraceptive"
(that's all one line, and include the quote marks so it only looks for
the exact phrases, not all the words independently) which will find you
several more sites.
