Study : Weight may affect breast cancer risk in women with an inherited BRCA mutation
Relevance: Medium
Strength of Science: Medium
Research Timeline: Animal Studies
Most relevant for: People with an inherited mutation in BRCA1 or BRCA2 concerned about their breast cancer risk
A study that looked at normal breast cells from women with an inherited BRCA mutation found more DNA damage among women who were overweight (based on a measurement known as body mass index) than those who were not overweight. The results suggest that maintaining a lower weight may reduce breast cancer among this high-risk population. (Posted 3/30/23)

Study : Increasing soy in your diet may lower your cancer risk
Most relevant for: People interested in reducing cancer risk
This study looked at a link between a diet rich in soy and cancer risk. With the addition of more recent literature, this study suggests that soy lowers the risk of cancer in the general population. (Posted 2/24/23)

Guideline : Guidelines on exercise, diet, and weight during cancer treatment
Relevance: Medium-High
Strength of Science: High
Research Timeline: Post Approval
Most relevant for: People currently undergoing treatment for cancer
Most professional guidelines on exercise, diet and weight management have focused on the health of the general population and cancer survivors. The American Society of Clinical Oncology (ASCO) has now published evidence-based recommendations for exercise, diet and weight specifically for people who are in active treatment for cancer.

Study : Physical activity may decrease fatigue associated with cancer treatment
Relevance: Medium-High
Strength of Science: High
Research Timeline: Post Approval
Most relevant for: Cancer patients who are experiencing fatigue related to cancer or its treatment.
Many cancer survivors experience fatigue during and after they complete treatment. This study looked at the effect of home-based physical activity on fatigue in cancer survivors. It also looked at whether frequent counseling encouraged people to start and continue their exercise routines. (Posted 8/1/22). Este artículo está disponible en español.

Study : Physical activity may prevent chemotherapy-related cognitive decline in women with breast cancer
Relevance: High
Strength of Science: Medium-High
Research Timeline: Post Approval
Most relevant for: People concerned about the impact of chemotherapy
Many people experience chemo brain or chemo fog (cognitive effects) during and after chemotherapy. Researchers looked at the impact of physical activity on chemotherapy-related decline in memory, attention and information processing in women with breast cancer. This study shows that more physical activity before and during chemotherapy is linked to better information processing after chemotherapy. (Posted 1/6/22)

Study : Drinking coffee or tea may improve survival after breast cancer
Relevance: High
Strength of Science: Medium-High
Research Timeline: Post Approval
Most relevant for: Women with breast cancer who drink coffee or tea.
In a study of 8,900 women with stage 1, 2 or 3 breast cancer, those who drank coffee survived longer after a breast cancer diagnosis than those who did not drink coffee. Both coffee and tea were linked to improved survival from any cause. Several factors were linked to greater coffee or tea consumption, so this finding must be taken with some caution. However, breast cancer survivors who are regular coffee or tea drinkers may find this research reassuring. (posted 8/31/21)

Study : Body Mass Index (BMI) may affect how well aspirin use protects against colorectal and ovarian cancer
Relevance: Medium-High
Strength of Science: Medium-High
Research Timeline: Post Approval
Most relevant for: People concerned about their risk of colorectal or ovarian cancer.
This study looked at the impact of daily aspirin use on the risk for many types of cancers and whether this effect can be modified by risk factors such as obesity, smoking, physical inactivity or a family history of cancer. Daily aspirin use:
- lowered the risk for colorectal cancer, but this effect was lost as Body Mass Index (BMI) increased.
- lowered the risk of ovarian cancer risk among obese women.
- offered little or no protection against breast, endometrial or advanced prostate cancer.

Most relevant for: Women who consume dairy or soy
Debate continues about whether consuming soy or dairy products increases breast cancer risk. This study looked at a large number of women and found no link between soy and breast cancer risk. The study did find that postmenopausal women who drank dairy milk have a small increase in breast cancer risk. (09/04/20)
