its been a while

I would ask for a referral for genetic counseling, and go from there. They will look at your family history and determine if testing for BRCA or other potential hereditary genes is appropriate. 

Counseling is an important step as they can also go through with you the issue of "answers". Now, I assume your mother and sisters never tested for BRCA or other genetic mutations. It is always best to test an affected member of the family first if possible as it can lead to certainty with your result. If they test, and were positive for a mutation then you can test JUST for that mutation (which would be under $500 and pretty quick turnaround). If you are negative for it, you are a true negative. If they test, and are negative, there is little reason in you testing unless there are other potential hereditary issues in your family that need to be discussed with a counselor.

Now, if your affected members are not tested, and you get a positive mutation result then it can be assumed it is likely that mutation may be related to the cancers in your family (though not necessarily). Other family members can then test for that mutation too and you can kind of trace it. In any event, a mutation would give you an idea of your risk based on quite substantial research at this point (at least for BRCA).

Complications arise if your affected family members are not tested and you get a negative result...as now there is no "context" for your result. You are considered an uninformed negative. There may be a mutation in your family that affected your affected family members, which you did not inherit so you are technically a true negative but you don't know this for sure. Or, they may not have a mutation either, and so your negative result does not clear anything up...there may be other reasons for the hereditary pattern in your family (an undiscovered mutation, a combination of genetic variations, and so on). So, the question becomes what do you do with that negative result when it is not a true negative result (it may be, but you don't know for sure). And that can come down to your own comfort with uncertainty and the risk assessment your genetic counselor can provide you.

With health insurance, if you quality, you would be covered (at least in great part). Without it, it can cost quite a bit if you are running a full panel (for BRCA1/2 and BART/reflex testing). There are different labs, but I paid around $3,000 through Ambry Genetics (testing is covered in Canada, but I traveled to the U.S.). Myriad is around $4,000. U of Washington is closer to $2,000 (I believe) but they do take a few months to get you results. Single-site testing or the three-site panel (the Ashkenazi panel) are both around $400-500.

I would recommend paying a little extra to test through Myriad or Ambry if you can.  University of Washington can be a LONG wait indeed.  

Good luck whatever you decide!
