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 : Study uses mice and brains from deceased Alzheimer’s patients to assess BRCA1 involvement

Relevance: Low

Strength of Science: Medium

Research Timeline: Animal Studies

Most relevant for: This research is not relevant to people

Researchers noted reduced levels of BRCA1 protein in the brains of mice and deceased Alzheimer's patients. While this study is interesting early work on the biology of Alzheimer's disease, the focus was primarily Alzheimer's disease, rather than the effect of BRCA1 mutations on Alzheimer's. Therefore, this study's observation may be something that is seen in Alzheimer's patients, but does not necessarily cause the disease. No studies suggest that BRCA1 mutation carriers are at increased risk for Alzheimer's disease. (12/22/2015)

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 : Effects of cancer diagnosis and treatment during pregnancy on the health and development of the child

Relevance: Medium-High

Strength of Science: Medium-High

View Related Clinical Trials

Most relevant for: Women who were diagnosed with breast cancer while pregnant

Very little work has studied how a woman's cancer diagnosis and treatment during pregnancy affects her child. This study of women who were diagnosed with cancer while pregnant looks at their children at ages 18 months and 3 years. The study found no difference in general, cognitive, and cardiac development when compared to children born to healthy mothers. (12/08/2015)

Study : Do antioxidants encourage the spread of cancer cells?

Relevance: Low

Strength of Science: Medium

Research Timeline: Animal Studies

View Related Clinical Trials

Most relevant for: The clinical relevance of this study for people is not clear

Scientists do not yet know why some cancers spread to other parts of the body (a process called metastasis). A study in mice suggested that high doses of some antioxidants (chemicals that can protect cells from damage) might actually make it easier for cancer cells to spread. (12/01/2015)

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

View Related Clinical Trials

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)

Study : Breastfeeding may reduce hormone receptor negative breast cancer risk

Relevance: Medium

Strength of Science: Medium-Low

Research Timeline: Human Research

Most relevant for: Women who are pregnant or have just given birth and are deciding about breastfeeding

Previous studies have shown that women who breastfeed have a reduced breast cancer risk. This study examines this association in the different breast cancer subtypes (ER, PR, HER2 negative/positive) and finds that breastfeeding is associated with a reduced risk of ER-/PR- breast cancer.

Article : What “The Truth About Cancer” got wrong about BRCA mutations and cancer

Relevance: Low

Quality of Writing: Low

Most relevant for: Because this video is full of medical misinformation, it is not relevant for anyone making healthcare decisions

A website called thetruthaboutcancer.com, created a 9-part docu-series titled “The Truth About Cancer: A Global Quest” (TACGQ). The video states that Angelina Jolie’s decision to remove her breasts was one made out of fear; one commentator states that her decision was “barbaric." This video contains a lot of dangerous misinformation about BRCA mutations and inherited cancer. FORCE XRAYS provides the following point-by-point analysis on "The Truth About Cancer." (11/10/2015)

Study : Impact of familial breast cancer risk on young girls

Relevance: Medium-High

Strength of Science: Medium

Most relevant for: Young women and girls from high-risk breast cancer families

Does growing up in a family that is at high risk for breast cancer affect young girls? Recent research found girls from families with BRCA mutations and/or a strong family history of cancer to be as well adjusted as peers of the same age. The one difference was that girls from families facing breast cancer risk had more stress related to breast cancer than their peers. While these findings are reassuring, parents know their children best, and they should ask for help if they believe their daughters are not coping well. (11/03/2015)

Study : New research may lead to a blood test that detects breast cancer recurrence earlier

Relevance: Medium

Strength of Science: Medium

Research Timeline: Human Research

Most relevant for: People diagnosed with early stage breast cancer

Recent headlines announced a blood test that can potentially predict which breast cancer survivors are at risk of recurrence. This particular blood test, one of many being developed, is sometimes called a “liquid biopsy.” This early research focuses on a technique that is promising, but not yet available to breast cancer survivors.
