Hormone Therapy May Triple Risk of Breast Cancer

Posted Jan 16, 08 5:33 CST in Science & Health 

(Newser) – Millions of women who take combination hormones to counter symptoms of menopause may be three times more likely to develop a certain type of breast cancer, according to a new study. Most researchers assumed it takes five years of daily estrogen and progestin to increase cancer risks, but the threat may increase substantially in just three years, according to research published in Cancer Epidemiology, Biomarkers and Prevention.

The risk only increased for lobular breast cancer, which accounts for 15% of breast cancer cases each year. Many doctors still offer the controversial therapy to treat menopausal symptoms like hot flashes, despite its link to cancer. "Nothing is risk-free. A lot of women need combination hormones because they're miserable," said one gynecologist. "If it's three years instead of five, we'll deal with that."

    Breast Cancer May Vanish Without Chemo Breast cancer goes into spontaneous remission far more often than had been believed, a new study has discovered. Researchers found that a fifth more cancers were found in women screened every two years than in a group screened once in six years, leading them to conclude that many cancers may vanish on their own—and raising the possibility that some women are undergoing unnecessary chemotherapy, the Daily Telegraph reports.

    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 Linked to Breast Cancer 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.   More »
