FORCE’s eXamining the Relevance of Articles for Young Survivors (XRAYS) program is a reliable resource for breast cancer research-related news and information. XRAYS reviews new breast cancer research, provides plain-language summaries, and rates how the media covered the topic. XRAYS is funded by the CDC.
Eating meat has been suggested to increase breast cancer risk. The recent Sister Study looked at meat type, cooking methods and breast cancer risk in a study of 42,012 women. (9/10/19)
Vitamins are an essential part of our diet. Vitamin supplements are often used to improve general health. This study explores how vitamin B supplements may affect breast cancer risk in women with BRCA mutations. (5/17/19)
Current breast cancer treatments can negatively affect cardiovascular health. Recently, the American Heart Association released its first scientific statement on cardiovascular disease and breast cancer. This statement includes a comprehensive overview of the prevalence of both diseases, shared risk factors, cardiotoxic effects of therapy and the prevention and treatment of cardiovascular disease in breast cancer patients.

The link between alcohol intake and breast cancer is well known, but most studies have involved only White women. Recently, a large study of more than 22,000 African American (AA) women found that similar to White women, increased alcohol consumption is associated with a greater risk of breast cancer. (10/27/17)
Past studies using mostly animal models showed a link between use of hair products (dyes, straighteners and relaxers) and increased risk of certain cancers. In this study, researchers looked at data on hair product use among African-American (AA) and White women to see if certain types of hair products increased breast cancer risk, and how that risk might differ between race and breast cancer hormone status.

The World Health Organization’s International Agency for Research on Cancer (IARC) classified night shift work as a possible risk factor for breast cancer in 2007, although the majority of the evidence for this claim came from studies of animals after their normal sleep-wake cycle was disrupted. The authors of this study surveyed women from three different cohorts to examine whether night shift work can increase a woman’s breast cancer risk. (3/24/17)
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)
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)
This study found an association between prenatal exposure to the pesticide DDT, and an increased risk of women developing breast cancer. While this study does not prove that DDT exposure directly causes breast cancer, it serves as a reminder that pregnant women's exposure to toxic environmental agents can affect their children's risk for disease later in life.
