She's now  34 and said she's cancer-free.<\/p>\n<p>  In 2013, an MRI screening at the Memorial Sloan Kettering Cancer  Center in New York revealed signs of cancer in Golkin-Nigliazzo's  right breast. She then had a spot mammogram and biopsy performed.<\/p>\n<p>    The next day, Golkin-Nigliazzo received a phone call from her    doctor.  <\/p>\n<p>    \"She said, 'We found some malignant cells.' That's what she    started off with, and everybody knows that's breast cancer,\"    Golkin-Nigliazzo said.  <\/p>\n<p>    Because of her family history, Golkin-Nigliazzo was tested    after her diagnosis for mutations on the BRCA1 and BRCA2 genes,    which increase the risk of breast and ovarian cancers in women.  <\/p>\n<p>    The tests came back negative.  <\/p>\n<p>    \"I was more surprised to hear my genetic results rather than my    own diagnosis, because I assumed I inherited some kind of    genetic mutation that would make me susceptible to developing    breast cancer,\" Golkin-Nigliazzo said. Additionally, behavioral    and environmental risk factors had been determined to be    unlikely.  <\/p>\n<p>    \"So right now, I am one big genetic question mark,\" she said.    \"We don't know all of the genes that have an effect on cancers,    but I know that with the amazing research that is being done by    geneticists, when my daughter is old enough to take advantage    of genetic testing, there will be more genes to test, and we    will be able to learn more about our genetic risk.\"  <\/p>\n<p>    Golkin-Nigliazzo, the mother of an 18-month-old daughter, said    she has enrolled as a participant in a number of studies at    Memorial Sloan Kettering's research lab on unknown genetic    mutations that may increase breast cancer risk.  <\/p>\n<p>    One reason why the new mom has decided to participate in    research is because of her daughter, she said.  <\/p>\n<p>    \"When I found out I was having a little girl, I knew I would be    passing on my familial risk of breast cancer. Being able to    participate in these studies is my own way of helping    researchers identify the genes that affect breast cancer risk    in many women, including my daughter,\" Golkin-Nigliazzo said.  <\/p>\n<p>    \"I hope that genetics (research) takes us to the next level so    that she knows all of her risks and is able to really conquer    cancer head-on if that's something in her future,\" she said.    \"There's something in my blood that's genetically predisposing    myself and my family to the disease, and one day, I'm hopeful    that science will uncover that.\"  <\/p>\n<p>    But what's the likelihood of carrying such mutations?  <\/p>\n<p>    Researchers are getting a step closer to answering that    question, especially in Jewish women like Golkin-Nigliazzo.  <\/p>\n<p>    A new study of 1,007 women of Ashkenazi Jewish ancestry who had    been diagnosed with breast cancer found that a whopping 903 had    none of the widely known mutations in the BRCA1 or BRCA2 genes.  <\/p>\n<p>    Rather, among those 903 women, 31, or 3.4%, carried a damaging    mutation in lesser-known genes that are related to breast    cancer. And seven, or 0.8%, carried a different mutation on    BRCA1 or BRCA2 than what's widely known.  <\/p>\n<p>    \"I am an Ashkenazi Jew, and I personally found this article to    be particularly fascinating,\" Golkin-Nigliazzo said.  <\/p>\n<p>    The DNA samples were sequenced, and the researchers targeted 23    established and candidate breast cancer genes, including BRCA1    and BRCA2.  <\/p>\n<p>    The researchers found that overall, 142, or 14.1%, of the women    carried a germline mutation responsible for their breast    cancer, which broke down to 11% in the BRCA1 or BRCA2 genes and    3.1% in CHEK2 or another breast cancer gene.  <\/p>\n<p>    However, the study had some limitations, including that only    those genes known or suspected to harbor breast cancer-related    mutations were sequenced and considered for the study.  <\/p>\n<p>    Also, more research is needed to determine whether or how the    findings could be applied to non-Jewish populations.  <\/p>\n<p>    \"This paper is part of an ongoing quest to identify women at    high risk for breast cancer,\" said Dr. Matthew Ellis, professor    and director of the Lester and Sue Smith Breast Center at    Baylor College of Medicine, who was not involved in the new    study.  <\/p>\n<p>    \"We are inexorably moving towards a world where there will be    widespread, even universal, genetic screening to risk-stratify    patients for early diagnostic techniques, such as mammography    and MRI and for surgical intervention,\" he said. \"This paper is    a further step in that direction by looking beyond BRCA1 and 2,    as there are dozens of other genes that, when abnormal, also    increase breast cancer risk.\"  <\/p>\n<p>    The researchers wrote in the study that Ashkenazi Jewish    patients with breast cancer can benefit from testing for all    breast cancer genes.  <\/p>\n<p>    \"Approximately half of the patients with a damaging mutation in    any breast cancer gene did not have a family history suggesting    inherited predisposition,\" the authors wrote. \"Therefore, to    limit genetic testing to patients with a suggestive family    history is to miss about 50% of patients with actionable    mutations.\"  <\/p>\n<p>    \"The most recent national screening guidelines recommend    genetic testing for all Ashkenazi Jewish patients with breast    cancer,\" the authors wrote. \"This recommendation is fine, but    testing women only after they develop cancer severely limits    the power of precision medicine.\"  <\/p>\n<p>    Though more inherited genetic mutations associated with breast    cancer have been identified in recent years, the scientific    understanding of those mutations and how they impact patients    needs to be more fleshed out, Ellis said.  <\/p>\n<p>    \"The biology behind each one of these genes and the    epidemiology is becoming increasingly well-understood,\" he    said. \"Although for now, I would say we're still struggling    with this in clinic.\"  <\/p>\n<p>    For instance, when one of the rarer genetic mutation diagnoses    is made, there are still many questions about what type of    guidance should be provided to a patient, he said.  <\/p>\n<p>    \"Should you take (the hormone-blocking drug) tamoxifen? Should    you have your mastectomies? Or should you just have more    frequent screening?\" Ellis said. \"Each one of these gene    abnormalities is a separate diagnosis. It's a different gene, a    different biology, and it might take a different approach. So    there's an awful lot of work ahead of us.\"  <\/p>\n<p>    Golkin-Nigliazzo hopes work in the field of breast cancer    research might hold clues to the familial breast cancer that    she and some of her relatives have been diagnosed with.  <\/p>\n<p>    For treatment, Golkin-Nigliazzo decided to have a double    mastectomy, a procedure in which both of her breasts were    removed. Her father, Jeffrey Golkin, and now-husband, David    Nigliazzo, stayed by her side during her appointments and    surgery.  <\/p>\n<p>    Since the cancer was detected early, Golkin-Nigliazzo said,    \"finding the breast cancer at 30 was empowering rather than    scary, because I knew that I had done what I needed to do to    make my chances of survival as high as possible.\"  <\/p>\n<p>    \"The fact is, researchers are just scratching the surface and    making breakthroughs in genetics every day,\" Golkin-Nigliazzo    said.  <\/p>\n<p>    \"To say that identifying a genetic mutation that increases    breast cancer risk is like finding a needle in a haystack is an    understatement. The human genome is incredibly complex,\" she    said. \"There are no known genetic mutations associated with my    genetic background, but that doesn't mean that there aren't any    out there.\"  <\/p>\n<p><!-- Auto Generated --><\/p>\n<p>The rest is here:<br \/>\n<a target=\"_blank\" href=\"http:\/\/www.cnn.com\/2017\/07\/20\/health\/breast-cancer-genes-jewish-women-study\/index.html\" title=\"Study sheds light on the 'other' breast cancer genes - CNN International\">Study sheds light on the 'other' breast cancer genes - CNN International<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p> \"Because of my family history, I expected to be diagnosed at some point,\" said the New York-based real estate attorney.
