【新研究】戴胸罩并不增加女性乳腺癌的患病风险


人们担心胸罩可能阻碍乳房的淋巴结循环和引流，导致有害物质堆积而增加乳腺癌的风险。甚至有“专家”也说: “胸罩增加乳腺癌风险”。一项发表在 Cancer Epidemiology, Biomarkers & Prevention 最新的研究证实，乳罩与乳腺癌之间并无任何联系，佩戴胸罩是安全的。
 


该研究的作者，来自华盛顿大学公共卫生学院的博士研究生Lu Chen说: “我们并未发现胸罩与乳腺癌有关的证据”。

此项研究是在NCI(the National Cancer Institute)的资助下进行的。Lu Chen对超过1000名确诊乳腺癌的女性进行研究( 454 invasive ductal carcinoma (IDC) cases and 590 invasive lobular carcinoma (ILC) cases)，并与469名无乳腺癌的女性进行对比(469 control women)。在综合多种因素(罩杯大小、新旧程度、每天戴的平均时数、戴有钢圈撑托的那种、第一次戴乳罩的年龄等)后，Lu发现二者并无联系。

Bra Wearing Not Associated with Breast Cancer Risk: A Population-Based Case–Control Study

  1. Christopher I. Li

Abstract

Despite the widespread use of bras among U.S. women and concerns in the lay media that bra wearing may increase breast cancer risk, there is a scarcity of credible scientific studies addressing this issue. The goal of the study was to evaluate the relationship between various bra-wearing habits and breast cancer risk among postmenopausal women. We conducted a population-based case–control study of breast cancer in the Seattle–Puget Sound metropolitan area that compared 454 invasive ductal carcinoma (IDC) cases and 590 invasive lobular carcinoma (ILC) cases diagnosed between 2000 and 2004 with 469 control women between 55 to 74 years of age. Information on bra-wearing habits and other breast cancer risk factors was collected from study participants through in-person interviews. Multivariate adjusted odds ratios (OR) and their associated 95% confidence intervals (CI) were estimated using polytomous logistic regression. No aspect of bra wearing, including bra cup size, recency, average number of hours/day worn, wearing a bra with an underwire, or age first began regularly wearing a bra, was associated with risks of either IDC or ILC. Our results did not support an association between bra wearing and increased breast cancer risk among postmenopausal women. Cancer Epidemiol Biomarkers Prev; 1–5. ©2014 AACR.
