Hormone Therapy for Metastatic Breast Cancer

Anti-cancer hormone therapies for breast cancer all act to block the effect of estrogen on breast cancer cells but achieve it through a variety of different modes of action.

The selective estrogen-receptor degrader is currently the only hormone therapy to be a pure anti-estrogen with no estrogenic activity. This is important because high estrogen levels can stimulate cancer cells to grow and even spread, hence why it is to be avoided.

			Twice-a-year MRI more effective than mammograms for women with genetic breast cancer risk Getting magnetic resonance imaging scans twice a year instead of one annual mammogram is far more effective at detecting early breast cancers in young women with a high-risk genetic profile than mammograms alone, according to a research team based at the University of Chicago Medicine and the University of Washington, Seattle.

			Postmenopausal women who lost weight had lower risk of developing invasive breast cancer In a study of postmenopausal women, participants who lost weight had a lower risk of developing invasive breast cancer than those who maintained or gained weight. Published early online in cancer, a peer-reviewed journal of the American Cancer Society, the findings suggest that weight loss may help lower postmenopausal women's breast cancer risk.

	Screening does not reduce breast cancer mortality Fewer and fewer women die from breast cancer in recent years but, surprisingly, the decline is just as large in the age groups that are not screened. The decline is therefore due to better treatment and not screening for breast cancer.

	Vitamin D may reduce breast cancer mortality in women with lower BMI Vitamin D is already well known for its benefits in building healthy bones. A new study supports the idea that it also may reduce cancer risk as well as breast cancer mortality, especially in women with a lower body mass index.

	Aggressive breast cancer cells hijack protective protein to aid growth A new study has revealed that a protein known to protect healthy cells also protects cancer cells in aggressive breast cancer.

	Nanoparticles show promise in treatment for triple-negative breast cancer, finds study Approximately 10-20 percent of diagnosed breast cancers are found to be triple-negative, meaning the breast cancer cells test negative for estrogen and progesterone receptors as well as HER2 receptors, genes that can play a role in the development of breast cancer.

	Processed meat consumption may increase breast cancer risk, meta-analysis suggests Studies on red and processed meat consumption with breast cancer risk have generated inconsistent results. An International Journal of Cancer analysis has now examined all published studies on the topic.

	Stevens researchers develop new class of molecules for breast cancer treatment Researchers at Stevens Institute of Technology and colleagues have designed and developed a new class of molecules that use a never-before-known mechanism that may halt or destroy breast cancer tumors, particularly for patients with drug-resistant or dangerously metastatic stages of the disease.

	Study: Second opinion can potentially change the diagnosis of breast cancer patients It's early morning and a team of more than 20 professionals cram around a long table in a dark room, peering at slide after slide of black-and-white mammogram images crossing the screen.

	Mitochondrial pathway found to be involved in breast cancer Researchers have discovered a molecular pathway that controls the movement of mitochondria within breast cancer cells and influences invasiveness.

	Researchers simulate how different breast tissues respond to heat from MRIs No woman's breast tissue is the same, so MRIs detecting and monitoring cancer shouldn't treat them all the same.
