Study: Early research on a drug to prevent breast cancer

Many researchers are interested in non-surgical options to reduce the higher-than-average risk of developing breast cancer in BRCA mutation carriers. This research study identified a type of drug, called a “RANK ligand inhibitor,” that may prevent breast cancer. Among mice that were genetically engineered to have no BRCA1 genes, those that were given the drug developed tumors less frequently than those that did not. While this is an exciting early study for BRCA mutation carriers, more work and human clinical trials need to be done before this can be used as a prevention therapy in humans. (7/12/16)

Update added 11/24/19: The RANK ligand inhibitor, denosumab is currently being studied as a possible breast and ovarian cancer preventive agent in human clinical trials.

Study: Breast cancer risk model updated for average risk women with genetic, lifestyle and environmental information

A number of factors are known to increase breast cancer risk, but some of these factors have not been included in models to predict breast cancer risk. This study looks at an updated model that includes some of these factors, such as genetics, smoking, and drinking. The goal of the model is to give women a more individualized breast cancer risk assessment. (6/29/16)

Study: Does light alcohol consumption affect your breast cancer risk?

Alcohol is known to increase breast cancer risk, but does that include light consumption? This study indicates that some breast cancer occurrences and mortality is due to light alcohol consumption. (06/21/16)

Study: Dense breast notifications are informative but hard to read and understand

Some states offer women dense breast notifications that are meant to explain that dense breasts are risk factors for breast cancer and can hide cancer on mammograms, and to identify appropriate supplemental screening options. But recent research found that this information is often not easy to read or understand, which questions the usefulness of the documents. (6/7/16)

Study: Do BRCA mutations affect fertility?

Age affects fertility. As women age, their ovaries release eggs that are not as healthy as those released in younger women. Fewer eggs are released each menstrual cycle as women age, making it harder for older women to become pregnant. Are women with BRCA mutations less fertile? Previous research suggested that BRCA mutations might affect women's fertility as she ages. A recent study found that BRCA1 mutation carriers may have slightly lower fertility than women without the same mutation, but more research is needed before this finding is useful for medical decision-making.

Study: More patients with invasive breast cancer opting for double mastectomies

There are a number of surgical options for treating invasive breast cancer. These include lumpectomy with radiation, a single mastectomy to remove only the breast with cancer, or a double mastectomy, which removes both breasts. A new study finds that more women are choosing double mastectomy, even though it does not increase overall survival for these patients. (5/3/2016)

Study: Is breast cancer risk increased in women who test negative for the BRCA mutation in their family?

Some women who do not carry a BRCA mutation, but come from a BRCA-positive family, still develop breast cancer. This research examines whether these women are at higher risk for breast cancer, or whether their risk is similar to women in the general population. (4/19/16)

Study: BRCA testing in young women with breast cancer

National guidelines recommend genetic testing for BRCA mutations in young women who are diagnosed with breast cancer. However, little is known about how women decide to get testing, or how they use genetic information to decide on treatment options. This study found that genetic testing is increasing among young breast cancer survivors, and it explores some of the factors that play into patients’ decision making about genetic testing. (3/22/16)

Study: What are the genetics underlying 12 different cancer types?

As gene sequencing has become more affordable, researchers and health care providers are now looking for mutations in many genes beyond BRCA1, BRCA2 and others that are associated with known hereditary cancer syndromes. By sequencing thousands of genes rather than just one or two, researchers can better understand which inherited mutations affect cancer risk. In this study, researchers sequenced thousands of genes in patients with one of 12 cancers, including breast, and catalogued which gene mutations are most commonly found in each cancer. (03/01/16)

Study: Smoking before or after a breast cancer diagnosis associated with poorer breast cancer survival

Cigarette smoking is an important public health issue that causes more than 480,000 deaths annually. Smoking increases the risk of many diseases, from heart disease to stroke. This research indicates that smoking before and or after a diagnosis of breast cancer affects survival, and also shows that it is never too late to quit smoking. (02/23/16)
