THURSDAY, Jan. 17 (HealthDay News) -- A newly discovered role played by the breast cancer gene BRCA1 in repairing damaged DNA may help explain why women who inherit a mutated version of the gene are more likely to develop breast and ovarian cancer.

It&#39;s now well known that people who carry mutations in the BRCA 1 and 2 genes are prone to ovarian and breast cancer, but new findings show that these genes also increase risk of certain other cancers as well.

Women with a genetic predisposition to breast cancer who are successfully treated for the disease may still be at high risk for ovarian cancer, says a University of Toronto study.

Doctors have long known that certain variations of genes boost the risk of breast cancer, but a new study says there is also a gene variant that offers modest protection against the disease.

A fast-acting pathway used by the drug tamoxifen to kill damaged breast cells before they become cancerous has been identified by scientists at Duke University.

Women with BRCA1 and BRCA2 gene  mutations can lower their risk of developing breast and  gynecologic cancers by having their ovaries removed. However,  the benefit depends on which mutation they have, researchers  have found.

Scientists identify four more genes that increase breast cancer risk which could result in better tests.

NEW YORK  - It's now well known that people  who carry mutations in the BRCA 1 and 2 genes are prone to  ovarian and breast cancer, but new findings show that these  genes also increase risk of certain other cancers as well.

Researchers from Canada believe they have identified the gene responsible for breast cancer tumor growth, a discovery that could possibly lead to a cure for the disease.

TUESDAY, Nov. 21 (HealthDay News) -- A woman's risk for breast cancer as she grows older appears strongly linked to the natural process of lobular regression, Mayo Clinic researchers have concluded.

The risk factors for breast cancer start early in a woman&#39;s life, even before birth, according to a major new study. High birth weight, a growth spurt between the ages of 8 and 14, and being a tall, thin adolescent

Scientists mapping genetics of two of the nation's leading cancers have found almost 200 mutated genes in breast and colorectal tumors, many of them never before suspected of helping cancer form and spread.

Childbearing factors, particularly those related to a first pregnancy, can influence a woman&#39;s risk of developing breast cancer, according to a study published in the Nov. 1 issue of the International Journal

The innate capacity to repair damaged DNA seems to affect a woman's chance of developing breast cancer. Deficient DNA repair appears to triple the risk of breast cancer, researchers have found.

A new study finds that, for some women, a mammogram may not be the best way to detect early breast cancer. Researchers say women who have the BRCA1 and BRCA2 genetic mutations run a better chance of having
