Hereditary Breast and Ovarian Cancer: What Every Jew Needs to Know



A little more than two years ago, the U.S. House of Representatives unanimously approved House Resolution 1522, designating the last week in September as National Hereditary Breast and Ovarian Cancer (HBOC) Week and the last Wednesday of the month as National Previvor Day. Ironically, when Rep. Debbie Wasserman Schultz (FL-20) first introduced the resolution in July 2010, just weeks after I’d lost my mother to breast cancer, I didn’t even know what the HBOC community was, let alone that I, together with Rep. Wasserman Schultz, was among its ranks. That all changed in August 2010, when the results of a simple blood test to check for the presence of BRCA (an acronym for BReast CAncer) gene mutations revealed that I do in fact carry one of these mutations, which we surmise I inherited from my mother.

Healthy BRCA genes—without mutations—function as tumor suppressors, helping the body fight off rapid and unregulated cell growth. Individuals with a BRCA gene mutation have a significant risk of developing breast and/or ovarian cancer within their lifetime—often at an earlier age than those in the general population. Although a woman’s risk of developing one or both of these diseases varies based on her personal family history and the specific gene mutation she carries (there are hundreds of different BRCA mutations), for those in the HBOC community, the risk of breast cancer can be as high as 87% (vs.12% in the general population) and as high as 50% (vs.1.5% in the general population) for ovarian cancer. Men, too, can carry BRCA mutations, which increase their lifetime risk of developing breast and prostate cancer. Like women, they can inherit a mutated gene from their father or their mother and, also like women, there is a 50% chance they’ll pass the mutation along to their children—both sons and daughters. BRCA mutations also are associated with pancreatic cancer and melanoma, as well as with fallopian tube and primary peritoneal cancer. Unlike some genetic diseases, such as Tay Sachs, in which individuals must inherit two “recessive” genes—one from their mother (who is a carrier) and one from their father (who also is a carrier)—in order to develop a particular disease, BRCA gene mutations are “dominant.” Inheriting just one BRCA gene mutation puts an individual at increased risk of developing cancer at some point during his or her lifetime. At the same time, some people with BRCA mutations will never develop either breast or ovarian cancer—some because of luck of the draw and others because they elect to take chemoprevention drugs or to have prophylactic surgeries to remove their breasts and/or ovaries, greatly minimizing their risks. These individuals, survivors of a genetic predisposition to cancer, are known as “previvors.”

As it always does, Hereditary Breast and Ovarian Cancer Week bridges Ovarian Cancer Awareness Month in September and Breast Cancer Awareness Month in October. This year, by coincidence it fell right in the middle of the High Holy Day season—with National Previvor Day on Yom Kippur. Then again, perhaps it’s not really such a coincidence—BRCA mutations are more prevalent among Ashkenazi Jews than in any other ethnic population. Overall, one in every 500-800 people is a BRCA mutation carrier, while among Ashkenazi Jews, approximately one in every 40 people (2.5% of the population) is a carrier, and most carriers are not aware of their BRCA status. Even though the majority of Ashkenazi Jews are not BRCA mutation carriers and only five to 10% of all breast and ovarian cancers are caused by BRCA mutations, it is important to know the possible signs of these hereditary cancers. These include a family member with:

  • Ovarian or fallopian tube cancer at any age
  • Breast cancer before age 50
  • Breast cancer in both breasts at any age
  • Both breast and ovarian cancer
  • Triple negative breast cancer
  • Male breast cancer

Other signs of hereditary breast cancer include more than one relative on the same side of the family with any of these cancers:

  • Breast cancer
  • Ovarian or fallopian tube cancer
  • Prostate cancer
  • Pancreatic cancer

If you suspect that you or a family member may be affected by HBOC, you may wish to contact a genetic counselor, who is specially trained to assess individuals’ personal cancer risks and help determine appropriate risk management strategies. The National Society of Genetic Counselors can help you find genetic professionals in your area. Facing Our Risk of Cancer Empowered (FORCE), an organization solely devoted to the HBOC community, also can provide resources and information helpful to you and your family.

Even if your family is not touched by HBOC, it is important to recognize the presence of hereditary cancer risk in the lives of countless families—many of them Ashkenazi Jews—and, in light of HBOC Week, to acknowledge the struggles and triumphs these families face in heeding our tradition’s call to “choose life so that you and your offspring shall live.”

    Dear Jane,
    Thank you for this timely reminder. 21 months ago my wife Irene died of breast cancer She found out that she had the BRCA gene only when here illness was already stage 4. She lived for 11 months after the diagnosis. My daughter Elana, now age 22 also has the gene and is being carefully monitored.
    During the past week, another Jewish friend of mine died of breast cancer.
    Whatever can be done to raise awareness of the Jewish susceptibility to this cancer WITHIN the Jewish community would be of great benefit. Please let me know if there is anything I can do to help.

    Dear Allan,

    Many thanks for your kind note and your offer of support. I am sorry for your loss. My mother was never tested for the mutation, but her sister also had breast cancer (and survived, but has not been tested) and so my sister and I opted for genetic counseling and testing shortly after our mom died. (To this day, I cannot believe that her oncologist never suggested it for her, especially knowing that she had two daughters.) Thankfully, my sister tested negative, but I was not so lucky. It’s been a long, difficult road, but I’m proud to say that just last week I finished the last step of my reconstruction, which feels like quite a milestone.

    If Elana is inclined, she might want to get involved with a local chapter of FORCE, whose “sisterhood” has been tremendously helpful and supportive to me throughout.

    Wishing both of you a sweet, healthy new year!

    Thank you for including that men need to be screened and look after themselves. Too many of my female relatives dies from ovarian, breast and pancreatic cancer.

    Our family is unique in that all my cousins are male. When I went for screening the counsellor was amazed that I hve no female cousins. That is our way of trying to stop passing on bad genes.

    Thanks for your comments, Marty. Just want to reiterate that males, too, can pass BRCA mutations along to the next generation — both sons and daughters.

    Wishing you a sweet and healthy new year.

    Having the BRCA mutation does not necessarily mean that you will get cancer. Studies show that most cancers are environmentally caused and not the result of hereditary.

      Big George,

      You are correct. As I noted in the post, only five to 10% of all breast and ovarian cancers are hereditary (caused by BRCA mutations). For those people who have a mutation, however, the likelihood of a cancer diagnosis is quite high, and in some carriers, exceeds 85% for breast cancer.

      As someone described it to me a number of months ago, if a flight attendant told you that the plane you were about to board had an 85% chance of crashing, would you get on it?

      At the same time, I certainly understand that the decisions about whether or not to get tested (and when) and whether or not to have prophylactic surgery (and when) are intensely personal and fraught with emotion. What’s right for one person can’t possibly be right for everyone, but knowledge and understanding of BRCA mutations are essential, no matter what you ultimately decide to do.

    The documentary film, “In the Family,” tells the story of various individuals undergoing BRCA testing and the decisions they make as a result of that testing. It will be screened in New York City on Sunday, November 4. RSVPs are required.
