Sorry....I'm getting ready to head into the clinic so it has taken me a few moments to reply ;)
I'm glad that your biopsy was normal and everything is looking good. It sounds like you are getting excellent care.
To answer your question:
A otherwise normal woman has a lifetime risk (between birth and age 80) of having breast cancer of about 1 chance in 8 all things considered.
So. What is the take home message?
Continue to routinely examine your breasts as directed by your doctor and you should be fine. There is no need to panic from what you have posted.
Does this make sense to you?
Don't forget to mash the positive feedback button for me...the one labeled "excellent" is the most fun to push by far ;)
It's safe for you to press the positive feedback button now if you so desire. And, never fear, even after you press that button I'll still be right here to continue helping you, but, as I do work for tips, I want to make sure you are happy before rating me.
