Adolescents With A Family History of Breast Cancer Who Avoid Alcohol May Reduce Risk

Friday, December 2nd, 2011

New research published online in Cancer presented results
answering questions of breast cancer patients about what their daughters might do to reduce their risk of breast cancer. They found that among adolescent girls with a family history of breast cancer (or maternal benign breast disease-a known risk factor for breast cancer) there was a significant association between the amount of alcohol consumed and increased risk of benign breast disease as young women.
Information from the Growing Up Today Study (GUTS) including females age 9 to 15 years in 1966 and who completed annual questionnaires from 1966 to 2001 and again in 2003, 2005, and 2007 were analyzed. In the final two surveys, participants between the ages of 18 and 27 at the time reported whether or not they had ever been diagnosed with benign breast disease. There were 67 who had this diagnoses as confirmed by breast biopsies and another 6,741 reported they had not had this diagnoses. In addition, breast cancer and benign breast cancer disease diagnoses were obtained from mothers, and maternal aunts and grandmothers.
Young women whose mothers or aunts had breast cancer were over 2 times as likely to have a diagnosis of benign breast disease as compared to the women in the control group (without family history). In addition, among adolescent girls who had mothers, aunts, or grandmothers with breast cancer , the more alcohol the girls consumed the more likely they were to develop benign breast disease. The authors said these results were consistent with results found for older women and alcohol use and concluded ” Our study suggests that adolescent females already at higher risk for breast cancer, in light of their family history, should be aware that avoiding alcohol may reduce their risk for benign breast disease as young women, which might be accompanied by reduced breast cancer risk later in life.”

Secondary Smoke and Hearing Loss

A study published in the July issue of the Archives of Otolaryngology-Head and Neck Surgery concluded that exposure to tobacco smoke nearly doubles the risk of hearing loss among adolescents.
Over 1,500 adolescents between the ages of 12 and 16 were part of the study and had been part of the 2005-2006 National Health and Nutrition Examination Survey. The subjects were evaluated in their homes, and subsequently given extensive hearing tests, and blood tests for cotinine, a chemical metabolite of nicotine at a medical center. Findings showed that those exposed to second hand smoke did worse on all sound frequencies tested and especially at the mid to higher frequencies that are important in understanding speech. In addition, those with the greatest exposure as measured by blood tests for cotinine, were more likely to have one-sided low frequency hearing loss. These are especially important finding because about half of all children in the United States are exposed to second hand smoke.
