After commissioning a systematic evidence review of the breast cancer screening literature to inform an update of its 2003 breast cancer screening interval guideline, the American Cancer Society (ACS) released new guidelines for women at average risk of breast cancer. The recommendations include...
For some early-stage breast cancer patients, accelerated partial-breast irradiation using multicatheter brachytherapy following breast-conserving surgery may be an excellent treatment option, as it has now been proven to be as effective as the current standard treatment—whole-breast...
Cancer is the result of normal cellular functions going wildly awry on a genetic level. That fact has been known for some time, but increasing evidence is showing that the human microbiome, the diverse population of microorganisms within every person, may play a key role in either setting the stage ...
In a study reported in the Journal of the National Cancer Institute, Ambrosone et al found that risk of estrogen receptor–negative breast cancer was reduced with later age at menarche in both parous and nulliparous African American women. Greater interval between menarche and first live birth ...
Accelerated partial-breast irradiation was designed to be a faster, more convenient, and potentially safer way for many women with breast cancer to reduce their mortality risk and help keep their cancer from returning after surgery. But a new study shows that despite the availability of accelerated ...
A multivariable analysis of clinical factors associated with tamoxifen use among premenopausal women with hormone receptor–positive breast cancer showed that fertility preservation was a significant factor and “the only predictor of both noninitiation and early cessation” of...
For a malignant tumor to form, cancer cells must evade the immune system's attack. Numerous studies have already shown that cancer spreads particularly aggressively if there is an unfavorable balance between suppressing and active immune cells in the tumor microenvironment. “But we didn't...
As reported by Solin et al in Journal of Clinical Oncology, 12-year results from the ECOG-ACRIN E5194 trial indicate that among women with ductal carcinoma in situ (DCIS) with low-risk clinical and pathologic characteristics, surgical excision without radiation therapy was associated with...

As reported in the Journal of Clinical Oncology by Rock et al, the Exercise and Nutrition to Enhance Recovery and Good Health for You (ENERGY) study has shown that a group-based behavioral intervention can produce...
A genetic test that helps predict whether some women’s breast cancer will recur might influence how chemotherapy is used, according to a study from Duke Medicine. The study found that low-risk patients who had the test appeared to opt for more treatment, and high-risk patients who were...
In a study assessing placebo effects reported in the Journal of Clinical Oncology, Mao et al found that sham electroacupuncture produced a greater reduction in hot flashes than placebo pills and gabapentin, with the greatest reduction being achieved with real electroacupuncture. Study Details In...
Women who are obese have a higher risk and a worse prognosis for breast cancer, but the reasons why remain unclear. A Cornell study published by Seo et al in Science Translational Medicine suggests that obesity changes the consistency of breast tissue in ways that predispose an individual to tumor...
Scientists have developed a blood test for breast cancer that may be able to identify which patients will suffer a relapse after treatment, months before tumors are visible on hospital scans. The test may uncover small numbers of residual cancer cells that have resisted therapy by detecting cancer...
Concerns about fertility kept one-third of young women with breast cancer surveyed in a recent study from taking tamoxifen, despite its known benefit in reducing the risk of breast cancer recurrence. In addition, the study found fertility concerns led one-quarter of women who started...
A study by researchers at Sweden's Karolinska Institutet is reportedly the first to suggest that cells in the tumor blood vessels contribute to a local environment that protects the cancer cells from tumor-killing immune cells. The results, published by Hong et al in the Journal of the...
Women who have inherited mutations in the BRCA1 or BRCA2 gene are more likely to develop breast cancer or ovarian cancer, especially at a younger age. Approximately 5% of women with breast cancer in the United States have mutations in BRCA1 or BRCA2, based on estimates in non-Hispanic white women. ...
The phase III NSABP B-40 (NRG Oncology) trial showed that the addition of bevacizumab (Avastin) to docetaxel-based neoadjuvant chemotherapy improved pathologic complete response rate, the primary endpoint, in patients with early HER2-negative breast cancer. In a report of secondary outcomes in The...
Adherence to aromatase inhibitor treatment for breast cancer declines over time. In a study reported in the Journal of the National Cancer Institute, Neuner et al found that introduction of generic aromatase inhibitors resulted in a reduction in decline in adherence among patients with breast...
