Study : Hormone therapy and breast cancer risk after ovary removal in women with a BRCA1 mutation

Most relevant for: Women with BRCA1 mutations who have had risk-reducing ovary removal and have never been diagnosed with breast cancer

Does hormone therapy (HT) alter the risk of breast cancer for woman carrying a BRCA1 mutation who have never been diagnosed with cancer? In this study, researchers showed that among women with BRCA1 mutations, HT use did not increase breast cancer rates for 10 years after ovary removal. More women taking combined estrogen plus progesterone developed breast cancer compared to those taking estrogen only, though this difference was not statistically significant. (9/7/18)

Article : Interview with Angelina Jolie's doctor promotes meatless diet and scientific inaccuracies

Most relevant for:

Dr. Kristi Funk, Angelina Jolie's Hollywood breast surgeon, is promoting her new book about breast cancer. This article from the UK newspaper The Times includes an interview with Funk about her book, which proposes that diet is responsible for breast cancer. This XRAYS addresses scientific inaccuracies in this article. (8/7/18)

Study : Evaluation of some direct-to-consumer genetic testing reveals inaccuracies and misinterpretations

Most relevant for: People who are considering or have had direct-to-consumer testing

A clinical genetic testing laboratory examined results from direct-to-consumer genetic testing ordered directly by patients. They found many instances of false positives—reported mutations that were not actually present—and in some cases, reports of variants that "increased risk," but were actually benign. This study emphasized the importance of involving genetics experts in the interpretation of genetic test results. (6/28/18)

Study : Disparities in research impact breast screening guidelines

Most relevant for: Women at average risk for breast cancer

For women at average risk of breast cancer, the United States Preventive Services Task Force (USPSTF) currently recommends beginning annual breast cancer screening at age 50. However, because these guidelines are largely based on data from white women, they may not be sensitive to racial differences.  A new study assesses the age distribution of breast cancer cases across race/ethnicity in the U.S. (6/21/18)

Study : Mutations in Lynch syndrome genes MSH6 and PMS2 may be associated with breast cancer

Most relevant for: Women with an MSH6 or PMS2 mutation

Some women with mutations in MSH6 and PMS2, two Lynch syndrome genes, may have a modest (2 to 3-fold) increased risk for breast cancer. (6/14/18 updated 09/25/19)

Article : The right not to know when not knowing is dangerous

Most relevant for: People with Icelandic heritage

Healthcare providers are bound by the guiding principle of doing no harm. But how does this concept apply to their patients who have not consented to genetic testing or who do not want to know their results? In that case, is providing test results more harmful or not? Anna Clausen explores these issues in the context of breast cancer gene testing in her Global Health Now article “The Right Not to Know: When Ignorance is Bliss but Deadly.” (4/20/18)

Study : FDA updates report on risk of lymphoma from breast implants

Most relevant for: Women who currently have textured implants or expanders or who have had them in the past

Note: On 07/25/19, the FDA announced a recall of Allergan BIOCELL textured implants and expanders, due to their association with BIA-ALCL. On October 27, 2021 the FDA announced stronger guidance on breast implant safety.

In March 2017, the Food and Drug Administration reported that patients with breast implants may be at increased risk for a rare type of lymphoma. This was covered in a previous XRAYS review. The FDA has continued to collect data since the first reported association in 2011. Recently, the agency released an update on the number of reported cases of breast implant-associated lymphoma and lifetime risk estimates for women with textured breast implants. (04/02/18)

Study : Take your time, follow your heart: strategies for communication about family planning

Most relevant for: Young high risk women

When a woman is newly diagnosed with a BRCA mutation, she faces many risk management decisions. Although many of these decisions impact family planning, little guidance is available on how to communicate this information. This study examines female previvors’ advice on effective strategies for discussing family planning decisions. (03/28/18)

Study : Should biannual MRIs replace annual mammograms in high-risk women?

Most relevant for: Women at increased risk for breast cancer due to an inherited mutation

The risk of breast cancer is exceptionally high in women who have a personal or family history of breast cancer or who carry a mutation in BRCA or certain other genes. More frequent screening is one strategy for early detection of breast cancer for these women. Study results presented at the 2017 San Antonio Breast Cancer Symposium suggest that MRI screening every 6 months may be more effective than the currently recommended annual breast MRI and annual mammogram in detecting early stage breast cancers-which are more treatable-in high-risk women.

Study : What is the risk of breast cancer recurrence after nipple-sparing mastectomy?

Most relevant for: Breast cancer patients who are considering or have had a nipple sparing mastectomy

Nipple-sparing mastectomy (NSM) offers better cosmetic results for women who have immediate breast reconstruction (at the same time as their mastectomy). Over the past decade, NSM has gained popularity among surgeons and patients. Studies show that women who keep their own nipples have higher rates of satisfaction and psychological well-being after mastectomy and reconstruction compared to women who lose their nipples. However, little data exists on the long-term risk of recurrence following NSM. New research adds to a growing body of evidence suggesting that risk of recurrence is low after NSM in carefully selected patients with breast cancer. (1/25/18)
