Drinking as few as three to six glasses of wine per week may increase a woman's lifetime risk of breast cancer by 15%, according to an analysis by Harvard researchers. The study, published Tuesday in the Journal of the American Medical Assn., reaffirms that heavy alcohol use raises breast cancer risk, and it adds that light drinking matters too. "Alcohol is a real risk factor, and the more you drink the higher your risk," said Dr. Steven A. Narod, the Canada research chair in breast cancer at the University of Toronto, who wrote a commentary accompanying the study.

Beverly Howey and her identical twin sister, Karen Duncan-Sherman, each found a breast lump in 2007. Howey's was cancer. Duncan-Sherman's was benign. The two women, now 45, couldn't have more similar genetics, and they live in the same place, Wall, N.J. Why did one develop cancer and not the other? Such questions have plagued breast cancer researchers for decades. Inherited genetic mutations, such as those in the BRCA1 and BRCA2 genes, make up only 5% to 10% of breast cancers. And though there's a clear link between a woman's natural estrogen exposure and her breast cancer risk, there's no magic level that equals cancer.

Two studies published in the October issue of Nature Genetics indicate that about 1 in 100 Jewish women of Eastern European descent, or about four times as many as previously thought, harbors a specific genetic mutation that increases her risk of breast and ovarian cancer. The gene in question, called BRCA2, is almost never mutated in other ethnic groups and is unrelated to a gene called BRCA1, which also increases the risk of breast and ovarian cancer.

A gene known to give many Jewish women a high risk of cancer also puts many U.S. Latino women at high risk, U.S. researchers reported this week in the Journal of the American Medical Assn. They found that 3.5% of Latinas entered in a Northern California breast cancer registry had the BRCA1 genetic mutation, compared with 8.3% of Ashkenazic Jews and 2.2% of non-Ashkenazic white women.

A British-American team has apparently wrapped up the mystery of inherited breast cancer, isolating a second gene that causes the disorder and thereby opening the door for increased screening in susceptible families. Like the first breast cancer gene, identified in September 1994, the newly discovered gene is thought to be responsible for about half of all inherited cases of breast cancer, which total as many as 18,000 cases a year in the United States.

Late Monday night, friends and colleagues started sending me Angelina Jolie's op-ed about her decision to have a double mastectomy. Like Jolie, I have the mutation in my BRCA1 gene that pushed my lifetime risk of developing breast cancer to nearly 90%. (It also raised my risk of ovarian cancer above 50%.) Also like Jolie, I chose to get a double mastectomy to reduce my risk of breast cancer to less than 5%. In 2007, I wrote a first-person story in the Los Angeles Times about finding out I had this mutation and how I decided what to do about it. Jolie is an icon of beauty -- and her disclosure doesn't change that.

A sustained dose of RU-486, the so-called abortion pill, prevented breast cancer tumors in mice with a genetic mutation that made them highly susceptible to the disease, researchers at UC Irvine report today. The mutation in a gene known as BRCA1 leads to uncontrolled cell growth in the mammary glands. About one in 800 women inherits a version of BRCA1 that is damaged in some way, and the National Cancer Institute estimates that up to 80% of such women will develop breast cancer.
