BRCA1 Gene News and Research

RSS

BRCA1 is a gene on chromosome 17 that normally helps to suppress cell growth. A person who inherits certain mutations (changes) in a BRCA1 gene has a higher risk of getting breast, ovarian, prostate, and other types of cancer.

Study shows how mutations in the BRCA1 gene lead to breast cancer

An international team of researchers led by Columbia University Medical Center's Herbert Irving Comprehensive Cancer Center and Sweden's Lund University has, for the first time, revealed how mutations in the BRCA1 gene lead to breast cancer.

Enhanced DNA-repair mechanism can cause breast cancer

Although defects in the "breast cancer gene," BRCA1, have been known for years to increase the risk for breast cancer, exactly how it can lead to tumor growth has remained a mystery.

Couples attending cancer counseling together better prepared to ease children's concerns

When women with children attend a counseling session before undergoing genetic testing for breast cancer, they are far more likely than their partners to be up front with their kids about the tests and the potential for cancers being inherited, according to a study released today here at the annual meeting of the National Society of Genetic Counselors.

Network approach finds potential breast cancer susceptibility gene

Like a crossword-puzzle solver who uses the letters in some answers to figure out others, researchers at Dana-Farber Cancer Institute and an international group of collaborators have used data on genes involved in inherited forms of breast cancer to identify a gene linked to non-hereditary cases of the disease.

HMMR gene emerges as a key player in breast cancer

Researchers in a multicenter international study have identified a new gene that, if mutated, may increase a woman's risk of breast cancer by more than a third.

BRCA1 gene plays significant role in non-small cell lung cancer

Barcelona, Spain: Researchers have found that the breast cancer susceptibility gene, BRCA1, plays a significant role in non-small cell lung cancer (NSCLC).

New insight into breast cancer development in high-risk women

Physicians who treat women with the breast cancer susceptibility gene BRCA1 often remove their patients' ovaries to eliminate the source of estrogen they believe fuels cancer growth.

Eight things you need to know about ovarian cancer

Ovarian cancer doesn't get the kind of attention breast cancer gets. It's not as common, and because survival rates are poor, it does not produce an army of survivors to raise awareness.

Discovery suggests location of genes for breast density, a strong risk factor for breast cancer

Studying the DNA of 889 people, gene hunters at the Mayo Clinic and H. Lee Moffitt Cancer Centers have identified a region on chromosome 5p that is significantly associated with dense breast tissue, a known risk factor for breast cancer.

Breast cancer prevention practices vary across Canada

Breast cancer preventive practices for Canadian women carrying the cancer gene vary across the country, says University of Toronto research, and many women are not taking advantage of the options available.

FOXP3 gene found to be involved in breast cancer

Researchers at the University of Michigan Comprehensive Cancer Center have identified a gene linked to the development of an aggressive form of breast cancer.

Chemotherapy may benefit all women with a BRCA1 mutation

Breast cancer patients who possess one of the so-called "breast cancer" or BRCA genetic mutations do not have a higher risk of dying than patients with no BRCA mutations, according to a detailed study by researchers at the Technion-Israel Institute of Technology and the University of Toronto.

Magnetic resonance spectroscopy for breast cancer

The American Cancer Society recently issued new recommendations for women with a higher risk of developing breast cancer, including those with a family history of breast or ovarian cancer, and those who may carry genetic mutations (BRCA1 or BRCA2) that make them more likely to develop the disease.

Size of family appears to affect breast cancer risk

Researchers have found that the probability of the breast cancer gene mutation BRCA among women with a history of breast cancer is greater when the number of older, female relatives in the family is smaller, according to a study in the June 20 issue of JAMA: The Journal of the American Medical Association.
