The BRCA 1 BRCA 2 test is expensive - about
$3,000 - and there is no point having it unless you are prepared to do something if it turns out positive. If you have the gene, will you have a double mastectomy so you will never get breast cancer? Will you have your ovaries removed? If not, will you worry, knowing that everyone who has the gene DOES NOT get breast or ovarian cancer...but a lot do? It's a very personal decision.
A negative result doesn't mean you would never get breast or ovarian cancer. I don't have the BRAC gene. No breast cancer or any other kind of cancer is in my family. I got breast cancer anyway. For me, the right decision was removing both breasts so I never had to worry about it coming back or showing up in the other breast. Not everyone would make the same decision and their reasons would be right for them.
If you have the gene and decide against surgery, you need to be aware of symptoms that could be ovarian cancer warning signs, do self breast exams, and get mammograms. Not all breast cancers can be detected with mammogram and MRI. Mine was supposed to be confined to one breast, as per all the tests, but the pathology report after my double mastectomy showed the "non-cancer side" had cancer too. Even if that breast had been cancer-free, I would still be happy with my decision.
Until you are sure of what you will do, my advice is to wait until you are sure.
