Genetic role in breast cancer probed

A new national clinical trial will investigate genetic and environmental causes of breast cancer by enrolling 50,000 sisters of women already diagnosed with the disease.

The causes of breast cancer are still being researched, although it is known the a woman&#39;s lifetime exposure to estrogen and her age at the time of her first childbirth play an important role.

NEW YORK  - A population-based study of   black and white American women with and without breast cancer   found that relatively few were carriers of mutations in BRCA1   or BRCA2 genes. Women who carry BRCA1 and BRCA2 gene mutations   are more susceptible to developing 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.

If your sister has breast cancer, there&#39;s a new way you can help fight for a cure. The National Institutes of Health is looking for 50,000 sisters of breast cancer patients for a study that will look at genetic

Doctors are encouraging a new group of people to consider getting tested for genes that raise the risk of breast cancer: men. Male relatives of women with such genes often do not realize that they, too, may carry them, and face greater odds of developing male breast cancer, as well as prostate, pancreatic and skin cancer, new research suggests.

U.S. health officials approved a genetic test on Tuesday that can provide women with early breast cancer an estimate of whether the disease is likely to return in five to 10 years.

NEW YORK  - A breast cancer family history,   as well as a woman's age and her own personal history of breast   cancer, may help identify women at increased risk of developing   ovarian cancer.

Gene mutations linked to breast cancer may pose less danger than previously believed, a new study shows.

THURSDAY, May 24 (HealthDay News) -- Four new studies released Thursday are shedding new light on the genetics of breast cancer, especially for one of the best-known breast cancer genes, BRCA1.

A new genetic test can tell doctors which breast cancer patients need to undergo the discomfort of chemotherapy and suggests that many women do not need to, researchers say.

A new report says a genetic profiling test already on the market accurately predicts which breast cancer patients will benefit from chemotherapy -- and who won't. It could help 80,000 women a year make better choices about their treatment.

A genetic mutation that raises the risk of breast cancer is found in up to 60 percent of U.S. women, making it the first truly common breast cancer susceptibility gene, researchers reported on Sunday.

FRIDAY, Dec. 15 (HealthDay News) -- U.S. researchers have developed two genomic tests to help doctors better predict how breast cancer patients will respond to hormonal therapy or chemotherapy.

Scientists have discovered a new cancer-causing gene that they believe could be a molecular master switch for the disease.
