Garcia, et al., “Risk Management Options Elected by Women after Testing Positive for a BRCA Mutation.” Different numbers that follow the same general trend can be found here: M. S.

  If screening works: Given that recurrence rates are different for different stages and types of breast cancer, the exact percentage of early-stage cancers that later metastasize is difficult to pin down. Here are a few estimates: Up to 30 percent. (Elia Ben-Ari, “A Conversation with Dr. Patricia Steeg on Redesigning Clinical Trials to Test Therapies That Could Prevent Cancer Metastasis,” NCI Cancer Bulletin 9, no. 12 (June 12, 2012), accessed March 13, 2014. www.cancer.gov/ncicancerbulletin/061212/page4). 21 to 25 percent for estrogen-receptor positive cancer with five or ten years of tamoxifen treatement. (National Cancer Institute, “Ten Years of Tamoxifen Reduces Breast Cancer Recurrences, Improves Survival,” March 20, 2013, accessed April 17, 2014, www.cancer.gov/clinicaltrials/results/summary/2013/tamoxifen-10yrs0313). About 30 percent of early-stage patients end up with recurrence. (A.M. Gonzales-Angulo, et al., “Overview of Resistance to Systemic Therapy in Patients with Breast Cancer,” Advances in Experimental Medicine and Biology, 608 (2007): 1–22). 25 to 45 percent of breast cancer patients develop metastatic cancer.

  Unfortunately, the idea that women: Over at Forbes, David Kroll was concerned “that women with breast cancer may think they are not being aggressive enough with their current treatment plan,” as well as that Jolie’s mastectomy might scare some women off from yearly mammograms and self-examinations. (David Kroll, “A Cautionary Perspective on Angelina Jolie’s Double Mastectomy,” Forbes, May 14, 2013. Accessed April 18, 2014. www.forbes.com/sites/davidkroll/2013/05/14/a-cautionary-perspective-on-angelina-jolies-double-mastectomy/.); At CNN.com, H. Gilbert Welch noted, “If American women saw themselves in Angelina Jolie—then that would be a problem. Because the next logical question is: Should I get a preventive mastectomy?” (H. Gilbert Welch, “What Angelina Jolie forgot to mention,” CNN.com, May 18, 2013. Accessed April 18, 2014. www.cnn.com/2013/05/17/opinion/welch-jolie-mastectomy/.); At Salon, Joan Walsh concluded her piece on Jolie with, “It would be wonderful if Jolie’s essay motivated more women to learn more about their breast cancer risk. It would be sad if it scared them out of screening, or into getting unnecessary mastectomies.” (Joan Walsh, “Angelina Jolie’s Choice Not the Only One,” Salon, May 14, 2013. Accessed April 18, 2014. www.salon.com/2013/05/14/angelina_jolie%E2%80%99s_choice_not_the_only_one/.) For more examples of how the media treated Jolie’s mastectomy, simply do an Internet search for “Jolie unnecessary mastectomy.”

  Some of the articles confused: It is worth noting that between 1993 and 2003, the rates of women with breast cancer—not necessarily just BRCA patients—choosing contralateral prophylactic mastectomy increased by about 150 percent, a trend that has justly concerned medical professionals. (Abenaa M. Brewster and Patricia Parker, “Current Knowledge on Contralateral Prophylactic Mastectomy Among Women with Sporadic Breast Cancer,” Oncologist, 16(7), (July 2011): 935–941.) Still, although it appears that contralateral mastectomy may not increase overall life span, I feel that dubbing these mastectomies “unnecessary” does an injustice to the women who choose them. Life span is not the only measure of an operation’s effectiveness and worthiness. For women without BRCA mutations who have already had cancer in one breast, and who are under fifty at the time of their first diagnosis, the risk of developing contralateral breast cancer is around 13 percent—about the same as an average woman’s chance of developing the disease in the first place. These women have already failed their first dice roll—is it so unreasonable for these same patients to worry about losing the roll again during round two? Who gets to decide what level of lifetime risk—what level of fear of breast cancer—is tolerable for an individual in the long run? Presumably, to these patients, a contralateral mastectomy may feel essential as a tool for remedying fear of a recurrence, as well as for reducing the relatively low risk of developing contralateral cancer.
