Adolescent alcohol consumption and breast cancer

14.11.2011
Alcohol consumption by adolescents may increase breast cancer risk in those with a family history of the disease

Breast cancer patients often wonder what their daughters might do to reduce their risk of also developing cancer. Are there dietary intakes or behaviors that can be modified by their daughters to lower their own chances of getting the disease? A new study published early online in CANCER, a peer-reviewed journal of the American Cancer Society, sought information relevant to this question.

Dr. Catherine Berkey, a biostatistician at Brigham & Women's Hospital and Harvard Medical School in Boston, led a team that investigated childhood and adolescent risk factors for benign breast disease among girls with a family history of breast cancer. Benign breast disease, a large class of breast ailments that can cause breast lumps or breast pain, is a known risk factor for breast cancer. The authors found that among adolescent girls with a family history of breast cancer (or maternal benign breast disease), there was a significant association between amount of alcohol consumed and further increased risk of getting benign breast disease as young women.

The investigators analyzed information from the Growing Up Today Study (GUTS, founded by co-author Dr. Graham Colditz), which includes females who were aged nine to 15 years old in 1996 and who completed annual questionnaires from 1996 to 2001, then again in 2003, 2005, and 2007. Participants provided information regarding alcohol consumption, age at first menstrual period, height, and body mass index.

In the final two surveys, the participants (who were aged 18 to 27 years at the time) reported whether they had ever been diagnosed with benign breast disease. A total of 67 reported receiving this diagnosis (confirmed by breast biopsy), while another 6,741 reported they had never been diagnosed with the disease. Also, participants' mothers reported their own cases of benign breast disease and breast cancer, as well as breast cancer in their sisters and mothers (maternal aunts and maternal grandmothers of the participants).

Young women whose mothers or aunts had breast cancer were more than twice as likely to be diagnosed with benign breast disease compared to young women with no family history. Young women whose mothers had benign breast disease also saw their own risk (for benign breast disease) nearly double. More importantly, among adolescent girls having a mother, aunt, or grandmother with breast cancer, the more alcohol the girls consumed, the more likely they were to develop benign breast disease as young women. The same held true for girls whose mothers had benign breast disease. These findings are consistent with previous studies (on older women) showing that drinking by adult women increases their risk of breast cancer.

"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" said Dr. Berkey.

Furthermore, girls with a family history who had the most rapid height growth spurt were at increased risk, whereas in girls with no family history, height and body shape impacted their chances of developing benign breast disease. These findings suggest that risk factors for breast cancer may differ between women with a family history of breast cancer and women without a family history.

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
