Is there anyone that also tested positive for both? I keep reading those that test positive for one or the other but not both. ...

 She has been an ovarian cancer survivor sense 2003. She now has a lump in her breast which they think is cancer. 

 What are my chances as her daughter and considering that she tested positive for both BRCA1 and BRCA2?

    You should see a certified genetic counselor, they can estimate your risk of being one, none or both. You can find a CGC at http://www.nsgc.org

    You have a 50% chance of having the same mutations as you mom, its a crap shoot.How old was your mom at the time of her ovca diagnosis? How old are you?  Any other siblings would also have the very same 50/50 chance, including males. I also echo the thoughts of Jeskachi, please seek the advice of a genetic counselor for genetic testing. Best wishes, be very vigilant and remember: knowledge is power!!!

    I would suggest that you meet with a genetic counselor.  As far as the risks, if your mother does have a mutation in both the BRCA1 gene and the BRCA2 gene, it is 50% for you to inherit the BRCA1 mutation and 50% for you to inherit the BRCA2 mutation.

    In that case, there are 4 possibilities.  You inherit both mutations (25%), you inherit just the BRCA1 mutation (25%), you inherit just the BRCA2 mutation (25%), and you inherited neither (25%).

    thought you can have either or , but not both.  my sister was tested for brca 1 and brca 2, came back positive for the brca 1. so when it was time for me to get tested, i just got tested for the brca 1 and came back positive for that gene.

    It is possible to have both. I read about it on the FORCE website. It is important to see a genetic counsellor.

    I would certainly chime in here and tell you that yes, you must see a genetic counselor.  Your dr. can write a note to get it covered by insurance.  Mine rejectected it three times, but he has written them, and they finally cleared it.

    Every single person is completely different.  Your chances are higher that you may carry the gene as your mom does, but it doesn't mean you do.

    since your mom does, it only makes sense to get tested for it.  Knowledge is certainly power and you can take appropriate action.

    Good luck to your mom!!
