I was wanting some advise about having genetic testing. My situation is this my mother was dx with breast cancer at 32 my sister(twin) this past June at the age of 30, my grandmother(maternal)in her early 60's. My sister had the genetic testing and it was confirmed that the brca-2 was neg. and the brca-1 was pos. @ 87%. Im just really blown away with all this information. I would like to hear from people who have gone through this and what they choose to do.
