New peptide could be effective treatment for triple negative breast cancer

A new peptide developed by researchers in Temple University's College of Science and Technology has demonstrated efficacy against triple negative breast cancer. The leptin receptor antagonist peptide, developed by researchers Laszlo Otvos and Eva ...

Researchers unlock how progesterone increases breast cancer risk

EAST LANSING, Mich. -- Researchers have identified how the hormones progesterone and estrogen interact to increase cell growth in normal mammary cells and mammary cancers, a novel finding that may explain why postmenopausal women receiving h...

Scientists bring cancer cells back under control

Scientists at The University of Nottingham have brought cancer cells back under normal control -- by reactivating their cancer suppressor genes. The discovery could form a powerful new technology platform for the treatment of cancer of the breast ...

Mammogram sensitivity depends on menstrual cycle

SEATTLE -- Try to schedule your screening mammogram during the first week of your menstrual cycle. It might make breast cancer screening more accurate for pre-menopausal women who choose to have regular mammograms. This recommendation comes from an ...

Radiation fears should not deter women from mammography screening

OAK BROOK, Ill. -- The risk of radiation-induced breast cancer from mammography screening is slight in comparison to the benefit of expected lives saved, according to a new study appearing online and in the January issue of the journal Radiology. ...

New risk factor for developing breast cancer

An Australian research team from the Peter MacCallum Cancer Centre, the University of Melbourne and the University of Queensland has identified a new risk factor for developing breast cancer. This has been published online in the journal Cancer Pr...

Consuming vegetables linked to decreased breast cancer risk in African-American women

(Boston) - Investigators from the Slone Epidemiology Center at Boston University School of Medicine (BUSM) have reported that African American women who consume more vegetables are less likely to develop estrogen receptor-negative breast cancer than...

Better marker for breast cancer may reduce need for second surgeries

A new material could help surgeons more accurately locate breast cancers, reduce the need for second surgeries and minimize pre-surgical discomfort for patients. Microscopic gas-filled spheres of silica, a porous glass, can mark the location o...

Gambling on breast scans

A mathematical tool known as a Monte Carlo analysis could help improve the way X-rays are used for mammography and reduce the number of breast cancers missed by the technique as well as avoiding false positives, according to research published this ...

Male Sex Hormones Cooperate With Breast Cancer Gene To Suppress Tumors

BRCA-2, a gene linked with breast and ovarian cancer, cooperates with male sex hormones to enhance its ability to activate transcription of genes, which may suppress tumor formation in normal cells, Salk Institute researchers have found. The study, published in the June 10 Proceedings of the National Academy of Sciences, provides details on how the normal form of the gene may work, and how mutant forms of BRCA-2 may malfunction and therefore likely contribute to the development of breast cancer. It also gives greater insight into the causes of male breast cancer. BRCA-2 is one of two genes (the other is BRCA-1) linked to at least 10 percent of all breast cancers; the mutant form appears in nearly all male breast cancers.
