Breast tissue cells exposed to this toxin retain a long-term memory, increasing the risk for disease. In a series of laboratory experiments, researchers discovered that when enterotoxigenic Bacteroides fragilis ETBF was introduced to the guts or breast ducts of mice, it always induced growth and metastatic progression of tumor cells. A description of the work is published in the January 6 issue of the journal Cancer Discovery. While microbes are known to be present in body sites such as the gastrointestinal tract, nasal passages and skin, breast tissue was considered sterile until recently, says senior study author Dipali Sharma, Ph. If your microbiome is perturbed, or if you harbor toxigenic microbes with oncogenic function, that could be considered an additional risk factor for breast cancer.

This information was previously available on guideline. Both sites were taken down on July 16, , because federal funding though AHRQ was no longer available to support them. Created in , the U. Preventive Services Task Force USPSTF or Task Force is an independent group of national experts in prevention and evidence-based medicine that works to improve the health of all Americans by making evidence-based recommendations about clinical preventive services such as screenings, counseling services, or preventive medications. This new pocket guide is an authoritative source for making decisions about preventive services. Between and , the Agency for Health Care Policy and Research now the Agency for Healthcare Research and Quality sponsored development of a series of 19 clinical practice guidelines.
Hormone Therapy for Breast Cancer
The past year brought the breast cancer community a CDK inhibitor for early-setting disease, the combination of a PD-1 inhibitor and preoperative chemotherapy in advanced disease, trastuzumab monotherapy for some older patients, third-line antibody-drug conjugate ADC therapy instead of chemo, and data on the risks posed by interval-detected breast cancers. The hazard for invasive disease-free survival iDFS declined by All patients received physician's choice of standard endocrine therapy for 5 to 10 years, with or without 2 years of adjuvant abemaciclib. The primary endpoint was iDFS. The results have potentially practice-changing implications but require longer follow-up to determine whether the iDFS benefit translates into improved overall survival, said Giuseppe Curigliano, MD, of the National Cancer Institute of Milan, who was not involved in the trial.
Hormone therapy to treat breast cancer uses drugs or treatments to lower levels or block the action of female sex hormones estrogen and progesterone in a woman's body. This helps slow the growth of many breast cancers. Hormone therapy makes cancer less likely to return after breast cancer surgery. It also slows the growth of breast cancer that has spread to other parts of the body.
