Alcohol Linked to Breast Cancer

Posted Apr 14, 08 9:44 AM CDT in Science & Health 

(Newser) – Alcohol can increase the risk of breast cancer in older women by more than 50%, according to a new study. In an analysis of data from more than 184,000 post-menopausal women, those who had one or two drinks a day were 32% more likely to develop breast cancer tumors, researchers found. Three or more drinks a day raised the risk 51% higher.  

"Regardless of the type of alcohol, the risk was evident," said the study's lead investigator, who presented the findings at a California meeting of the American Association for Cancer Research yesterday. Researchers theorize that alcohol might interfere with the way the body metabolizes estrogen. Breast cancer is the second most common cancer killer among women, after lung cancer.

    Weight Can Increase Risk of Breast Cancer There may be a direct connection between weight and breast cancer in women, MSNBC reports. Overweight women “have more exposure to estrogen,” one doctor said, "which we think increases their risk of several different cancers.” Breast cancer patients across the country are now coupling their therapy with weight loss programs, but the side effects of cancer treatment can make it even harder to shed the pounds.

    Gene Variants Increase Breast Cancer Risk Scientists have identified versions of a gene that confer a 50% greater chance of developing estrogen-responsive tumors, Bloomberg reports. The study, published in Nature Genetics, found two common gene variants on chromosome 5 that correlated with higher incidences of the types of cancer that respond to estrogen levels. Genetic testing could indicate which women might benefit most from hormone-blocking therapy. More »

    Alcohol and Hormones Raise Cancer Risk: Study Postmenopausal women who drink casually while taking hormones will raise their chance of getting breast cancer, researchers said today. A Danish study of 5,000 women showed that those on estrogen and other hormones increased breast cancer risk three-fold by downing one or two drinks a day; a third drink or more raised the risk by almost 5 times.

    Drug Therapy Cuts Risk of Breast Cancer Relapse New research shows that women can cut the risk of breast cancer recurring years later by taking certain drugs, the Washington Post reports. Studies show that the drugs, known as aromatase inhibitors, sharply reduced the risk of cancer's return after women had finished their regimen of the widely used tamoxifen. The findings could dramatically change the treatments breast cancer survivors are given. More »

    Women at Risk After Hormone Therapy: Study Breast cancer remains a risk for women even after they stop taking hormone therapy, researchers said yesterday. A follow-up to a 2002 study showed that women who dropped estrogen and progestin still had a 24% greater breast cancer risk. But their chance of a stroke, heart attack, or blood clot fell to normal levels after halting the therapy, Reuters reports. More »
