Rats with chemically induced mammary tumors fed fish oil with tamoxifen showed lower expression of genes that drive tumor growth and spread than rats on corn oil. Fish oil also raised some immunity genes tied to inflammation, which may work against the benefit.

Estrogen plus progestin more dangerous than thought
Rowan Chlebowski's team reported in JAMA that women who used estrogen plus progestin for an average of 5.6 years were 25 percent more likely to develop breast cancer and twice as likely to die from it, over follow-up running through August 2009.
Phytochemicals
Soy food doesn't affect breast cancer survival
Pooling four cohorts covering 18,312 women with invasive breast cancer, Vanderbilt's Xiao Ou Shu found those eating more than 23 mg of soy isoflavones daily were 9 percent less likely to die and 15 percent less likely to relapse. Neither result reached statistical significance.
Disease
Can breast milk help doctors screen for breast cancer?
Kathleen Arcaro of UMass Amherst and colleagues collected milk from both breasts of about 250 women scheduled for or recovering from a biopsy, isolated DNA from the cells and looked for methylation signals, comparing them with biopsy-assessed risk. She says the approach could personalize screening.
Drug
Gene mutation in breast milk may help diagnose breast cancer
Researchers tested breast milk from about 250 women who had had or planned a breast biopsy and found methylation of the SFRP1 gene more often in milk from biopsied breasts, suggesting milk might help gauge breast cancer risk. More research is needed to confirm it.
Minerals
NEW Studies Reveal Alarming Hidden Cause of Breast Cancer
Russell Blaylock reviews studies finding higher free iron and ferritin in the breast ductal fluid of cancer patients, with ferritin five times higher and aluminum about twice as high. He argues iron released from its binding proteins matters more than iron intake.
Vitamins
Higher vitamin D intake needed to reduce cancer risk (PR)
UC San Diego and Creighton researchers report in Anticancer Research that adults need 4,000 to 8,000 IU of vitamin D a day, far above the 400 IU that defeated rickets, to reach blood levels associated with about halving the risk of breast and colon cancer, multiple sclerosis and type 1 diabetes.
Lifestyle
Obesity linked to higher risk of breast cancer
Among 155,723 Women's Health Initiative participants, those with the highest body mass index were 35% more likely to develop triple-negative and 39% more likely to develop estrogen-receptor-positive breast cancer, while the most active women had lower risk of both.
Disease
Breast Cancer Breakthrough - Cut Your Risk of Death in Half
Mercola cites National Breast Cancer Foundation figures, including 200,000 new U.S. cases a year and a rise from one in twenty women diagnosed in 1960 to one in seven today, plus an American Institute of Cancer Research estimate that 40 percent of cases are preventable.
Supplements
Magnesium supplements relieve hot flashes in breast cancer patients
In a pilot trial, 25 breast cancer patients completed four weeks on 400 to 800 mg of magnesium oxide daily. Weekly hot flashes dropped from 52.2 to 27.7, a 41% fall, and hot flash scores fell about 50%. Fourteen of the 25 more than halved their score.
Disease
Hot flashes are signs of reduced risk of invasive breast cancer
Christopher Li and colleagues report postmenopausal women who ever had symptoms such as hot flashes were 50 percent less likely to develop invasive ductal or lobular carcinoma. More intense symptoms tracked with lower risk, independent of hormone therapy and body mass.
Drug
Study - Breast cancer screening guidelines from ACS are better
Colorado and Michigan researchers reanalyzed the same data the USPSTF and the American Cancer Society used and found women starting annual mammograms at 40 would see breast cancer deaths fall 40 percent, against 23 percent for those starting at 50.
Environment
Cigarette smoking boosts breast cancer risk
In the Nurses' Health Study, women who ever smoked were 6 percent more likely to be diagnosed with invasive breast cancer, and 20 pack-years before a first birth came with 18 percent higher risk. Postmenopausal smoking and passive smoking showed no increase.
Environment
Unrecognized Dangers Of Formaldehyde (PR)
The Cancer Prevention Coalition's Samuel Epstein faults a New York Times article on formaldehyde in wrinkle-free clothing for overlooking longstanding evidence of the chemical's carcinogenicity, detailed in five National Toxicology Program reports and linked to nasal and breast cancer.
Lifestyle
Smoking before menopause may boost breast cancer risk
A study of 111,140 women found smoking before menopause, especially before giving birth, modestly raised breast cancer risk, with the earliest and heaviest smokers most affected. Light and moderate smoking and secondhand smoke showed no increase.
Lifestyle
Social supports help breast cancer survival
Researchers followed 2,230 breast cancer survivors in Shanghai and found that, six months after diagnosis, women with greater social well-being had a 38 percent lower risk of dying and a 48 percent lower risk of recurrence.
Drug
False positive mammograms lead to anxiety, lower quality of life
Among 385 Dutch women with abnormal mammograms, the 233 with false positives reported more anxiety and lower quality of life than the 152 diagnosed with breast cancer, with effects lasting at least a year. Lead author Lideke van der Steeg says anxiety-prone women fared worst.
Diet
Western diet linked to breast cancer
PyMT mice fed a Western-style diet of 21.2% fat and 0.2% cholesterol developed twice as many tumours, 50% larger, as mice on a low-fat, cholesterol-free diet, and were likelier to have cancer spread to organs such as the lungs. Their blood cholesterol ran lower.
