  Notes

  Prologue

  Every person has two pairs of BRCA genes: Location of BRCA genes: “Hereditary Breast Ovarian Cancer Syndrome (BRCA1/BRCA2),” Stanford Medicine, Cancer Institute, accessed March 6, 2014, http://cancer.stanford.edu/information/geneticsAndCancer/types/herbocs.html.

  Scientists identified these genes in the 1990s: William Check, “BRCA: What We Now Know,” CAP Today, September 2006, www.cap.org/apps/cap.portaL?_nfpb=true&cntvwrPtlt_actionOverride=%2Fportlets%2FcontentViewer%2Fshow&_windowLabel=cntvwrPtlt&cntvwrPtlt%7BactionForm.contentReference%7D=cap_today%2Ffeature_stories%2F0906BRCA.html&_state=maximized&_pageLabel=cntvwr; Sarah Berger, “Genetics Pioneer Mary Claire King,” Moment, accessed March 6, 2014. www.momentmag.com/2013-guide-to-jewish-genetic-diseases.

  Lifetime chance of developing cancer chart: “BRCA1 and BRCA2: Cancer Risk and Genetic Testing,” National Cancer Institute Fact Sheet, accessed March 6, 2014, www.cancer.gov/cancertopics/factsheet/Risk/BRCA; Similar numbers at “Hereditary Breast Ovarian Cancer Syndrome (BRCA1/BRCA2).”

  In addition to having an elevated lifetime risk: Younger ages: National Cancer Institute “BRCA1 and BRCA2: Cancer Risk and Genetic Testing.”

  The median age of breast cancer diagnosis: “SEER Stat Fact Sheets: Breast Cancer,” Surveillance, Epidemiology, and End Results Program, National Cancer Institute, National Institutes of Health, accessed March 6, 2014, http://seer.cancer.gov/statfacts/html/breast.html.

  Triple-negative cancers are resistant: “BRCA1 and BRCA2: Cancer Risk and Genetic Testing.”

  BRCA mutations are pretty rare: “Genetics of Breast and Ovarian Cancer (PDQ®),” National Cancer Institute, National Institutes of Health, accessed March 6, 2014, www.cancer.gov/cancertopics/pdq/genetics/breast-and-ovarian/HealthProfessional/page2#Reference2.21; “Hereditary Breast Ovarian Cancer Syndrome (BRCA1/BRCA2).”

  yet this tiny segment accounts for fully 5 to 10 percent: “BRCA1 and BRCA2: Cancer Risk and Genetic Testing.”

  The BRCA1 and BRCA2 genes produce proteins: Tumor-suppressor genes: Stanford Medicine, “Hereditary Breast Ovarian Cancer Syndrome (BRCA1/BRCA2)”; Repairing cellular damage: National Cancer Sheet “BRCA1 and BRCA2: Cancer Risk and Genetic Testing.”

  Since as we age we all acquire genetic mutations: For an explanation of genetics and how cancer grows, see: “What Is Cancer?,” American Cancer Society, accessed March 6, 2014, www.cancer.org/cancer/cancerbasics/what-is-cancer; For an explanation of how tumor suppressors cause cancer, see: “How Genes Cause Cancer,” Stanford Medicine, Cancer Institute, accessed March 6, 2014, http://cancer.stanford.edu/information/geneticsAndCancer/genesCause.html.
