I have a higher risk of having breast cancer due to family history and have been told that my risk is 1 in 4. I have annual Mamograms and was told that I would qualify for preventative surgery. Unfortunately I don't fall within the guidelines to have genetic screening as my family history is all at my grandparents generation, there is only one woman ie my mother in the generation above me and she hasn't had it. This doesn't fit the guidelines.
The tamoxifen apparently has a 40% chance of preventing BC, it also has side effects mostly hot flushes and discharge. I don't know anyone who has been on tamoxifen and would love to hear some experiences before I decide what to do.
