Study : Do BRCA mutations affect fertility?
Relevance: Medium
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: Women with a BRCA mutation who want to become pregnant
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.

Article : New York Times report demonstrates need for genetic counseling, but doesn’t give the whole story
Most relevant for: People diagnosed with breast cancer
A New York Times report discussed how genetic testing could provide “grim data” without guidance for patients. While this is a valid concern, this report does not sufficiently emphasize certain important issues regarding genetic testing, particularly the need for genetic counseling by a health care provider with expertise in genetics before and after genetic testing.

Study : Do women who eat a high fiber diet have a lower risk of breast cancer?
Most relevant for: Adolescent and young adult women
Some researchers believe that dietary fiber may decrease breast cancer risk by lowering estrogen levels in the blood. However, many previous studies have failed to find a link between fiber consumption and lower breast cancer risk. The current study suggests that consuming high dietary fiber during adolescence and young adulthood may lower breast cancer risk, but more work needs to be done to confirm this finding. In the meantime, everyone is encouraged to eat a variety of high fiber foods for the many well-documented health benefits. (03/08/16)

Study : What are the genetics underlying 12 different cancer types?
Relevance: Medium
Strength of Science: Medium-High
Research Timeline: Post Approval
Most relevant for: People diagnosed with cancer
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
Relevance: Medium-High
Strength of Science: Medium-High
Research Timeline: Post Approval
Most relevant for: People who smoke cigarettes
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)

Study : How do ultrasound and mammography compare in breast cancer screening?
Relevance: Medium-High
Strength of Science: High
Research Timeline: Post Approval
Most relevant for: Young women at high risk for breast cancer with limited access to mammography and MRI is not easily accessible
Mammography has been shown to reduce breast cancer deaths; however, women in developing countries don’t have easy access to mammography. Ultrasound screening, on the other hand, is portable and less expensive, and could be an alternative to mammography. This study compared mammography to ultrasound in women with dense breasts and found the two techniques have similar cancer detection rates, although the false positive rate is higher with ultrasound.

Study : Sugar promotes tumor growth and metastasis in mouse model breast cancer
Relevance: Medium
Strength of Science: Medium
Research Timeline: Animal Studies
Most relevant for: People diagnosed with breast cancer
Previous human studies found associations between high sugar intake and breast cancer risk. This study looked at the direct effect of sugar on breast cancer growth and metastasis in mice. While researchers observed that sugar increased tumor growth and metastasis, more work needs to be done to see if this finding is relevant in humans. It is important to remember, the overall health benefits of limiting sugar intake remain undisputed. (02/02/16)

Study : Do parabens in personal care products increase breast cancer risk?
Relevance: Medium
Strength of Science: Medium
Research Timeline: Lab Research
Most relevant for: Women who use personal care products that contain parabens.
Parabens are chemicals that can mimic the hormone estrogen in the body. As estrogen has been shown to increase breast cancer risk, some people have asked if parabens found in some cosmetics and shampoos will also increase breast cancer risk. Many studies have shown that parabens in the quantities found in personal care products are safe. A recent study of human breast cancer cells suggests that in certain conditions, parabens could help some breast cancer cells grow. It is important to remember that this is early research; this single laboratory-based study does not conclusively prove that parabens are dangerous. More work, including human studies, needs to be done to understand if parabens increase cancer risk. (01/16/2016)

Study : How many children with cancer have mutations in genes that increase cancer risk?
Relevance: Medium
Strength of Science: Medium-High
Research Timeline: Human Research
Most relevant for: Survivors of childhood cancer and people with a family history of relatives diagnosed with childhood cancers
Many genes are associated with increased cancer risk in adults, but it is unclear how common these mutations are in children with cancer. This study found that about 9% of children with cancer carry mutations in a gene that is known to increase cancer risk. Over half of the mutations were in the TP53 gene, which is associated with increased cancer risk at a young age and increased risk of breast cancer in adults. (12/15/2015)

Study : Aerobic exercise lowers estrogen levels in premenopausal women at high risk for breast cancer
Relevance: Medium
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: High risk women with a BRCA mutation or a close relative with a BRCA mutation
Many treatments that lower estrogen levels also reduce breast cancer risk. Unfortunately, these treatments are also associated with negative side effects. A recent study looked at the effect of regular aerobic exercise on the estrogen levels of women who are at high risk for breast cancer. (11/14/2015)
