Article : FDA busts myths of preventing and treating cancer by eating apricot kernels, herbs, and other ingredients
Most relevant for: People diagnosed with or concerned about their risk for cancer
Maggie Fox (NBC News) writes about a new FDA report that warns of 14 "fraudulent” cancer products claiming to either cure or treat cancer (1). The companies that sell these products claim that many of them also prevent cancer, but are they safe or effective? (6/26/17)

Study : Does eating soy affect the risk of death in breast cancer survivors?
Most relevant for:
Is eating soy safe for people who have had breast cancer? This topic has been controversial among health care providers, patients, and survivors for many years because research has yielded mixed results. Some studies suggest people who have been diagnosed with breast cancer should eat more soy products, while other studies recommend they eat less or avoid it altogether. Which should it be? Adding to this research is a new study that asked breast cancer survivors about their soy consumption before and after diagnosis. (4/27/17)

Study : Research suggests exercise is safe for breast cancer patients at risk for lymphedema
Relevance: Medium-High
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: People with, or at high risk for lymphedema after breast cancer
Patients and health care providers are often concerned about how exercise affects lymphedema (swelling in the arm or hand) in breast cancer survivors or other women who have had lymph node biopsy at the time of mastectomy. Research on this topic has been mixed. A new study suggests that exercise after breast cancer treatment does not lead to lymphedema or worsen existing lymphedema. However, because this study was small, more work needs to be done to understand the relationship between exercise and lymphedema in cancer survivors. (2/22/17)

Study : Hot chili pepper component slows growth and kills laboratory-grown breast cancer cells

Most relevant for: This research is not relevant to people yet
Finding new treatments that target triple-negative breast cancer is an area of great interest. An early step in developing these treatments is learning more about the biology of tumor in the laboratory. This study looked at how capsaicin, the spicy component of chili peppers, might work with a protein found in many cancers, including triple-negative breast cancer, to stop cancer cell growth. This is the first step in a long process towards developing new treatments for triple-negative breast cancer. (2/14/17)

Study : High vitamin D levels at breast cancer diagnosis may be associated with a better prognosis
Relevance: Medium-High
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: Women at average risk for breast cancer and newly diagnosed women
Vitamin D is most known for its role in maintaining bone health but vitamin D has additional roles in keeping us healthy. In this study, researchers found that breast cancer patients who had the highest amounts of vitamin D in their blood (slightly over the recommended levels) had better health outcomes, including overall survival, than women with lower amounts of vitamin D. This finding adds to the growing evidence for the role of vitamin D in cancer, but it does not change how breast cancer is prevented or treated. (1/10/17)

Study : Is there a link between exercise and memory in breast cancer survivors?
Relevance: Medium-High
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: People diagnosed with early stage breast cancer
Exercise has many health benefits, but can it also help improve memory for breast cancer survivors? This research finds that breast cancer survivors who exercised more had less fatigue and distress (anxiety, depression, stress, and/or concern about recurrence) and scored better on memory tests.

Study : Breast cancer risk model updated for average risk women with genetic, lifestyle and environmental information
Relevance: Medium
Strength of Science: Medium
Research Timeline: Human Research
Most relevant for: Women at average risk for breast cancer
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?
Most relevant for: Women who drink alcohol and are concerned about their 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 : Can long periods of fasting protect against breast cancer recurrence?
Most relevant for: Breast cancer survivors
Previous research in mice suggested that long periods of fasting provide protection against factors that are associated with a poor cancer outcome. A new study associates prolonged fasting (13 hours or more) at night with a lower risk of breast cancer recurrence, but no association between fasting time at night and mortality. While these findings are interesting, more research needs to be done to confirm them. In the meantime, breast cancer survivors should discuss any concerns about nutrition with their health care providers. 05/30/16

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)
