Estrogen Blockers?

I have been diagnosed with ADH and will see an oncologist next week to discuss the possible use of estrogen blockers. What are oncologist ccalculations? How realiable are they?

Dear tk150:  We do not understand your question.  Statistics are the result of research, not calculations.  The oncologist is likely to discuss the potential benefits and risks of such an approach in your situation.

Is there a right or wrong answer to using estrogen blockers for ADH? I realize that ADH isn't cancer just a disorder that puts me at a higher risk to develop breast cancer. Has the research shown that it is better one way than the other? Estrogen blockers vs. monthly breast self-exams, MRI's of the breast and noting any type of changes in the breast? I'm only 54 years old and not really sure what to do from here? I have a young teenager at home and would like to do everything proactively that I can.
Thank you for taking the time to answers my (our) questions.
