Cigarette smoking, alcohol consumption and risk of breast cancer in young women

Cigarette Smoking Is Not Associated with Breast Cancer Risk in Young Women

“…Our results are consistent with the bulk of published literature on this topic, which do not find significant relationships between smoking and overall incident invasive breast cancer risk among young or premenopausal women (3)(4)(5)(16)(17)(18)(19)(20)(21). A review of the literature by IARC (22) and a pooled analysis on breast cancer and smoking by the Collaborative Group on Hormonal Factors in Breast Cancer (23) both conclude that there is no overall association between smoking and breast cancer risk.…”

“…Epidemiologic studies of cigarette smoking on breast cancer risk during this developmental period have produced inconsistent results (2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12)(13)(14). However, recent cohort studies (7)(8)(9)(10), including two with mainly young women (7,10), suggest an effect of smoking at an early age.…”

Smoking before the birth of a first child is not associated with increased risk of breast cancer: findings from the British Women's Heart and Health Cohort Study and a meta-analysis

“…(Adami et al, 1988;Hunter et al, 1997;Lash and Aschengrau, 1999;Innes and Byers, 2001;Egan et al, 2002;Band et al, 2002;Lash and Aschengrau, 2002;Kropp and Chang-Claude, 2002;Fink and Lash, 2003;Reynolds et al, 2004) The pooled analysis for these 11 studies, together with the study presented here, included 6528 breast cancer cases and provided an odds ratio (95% CI) of 1.07 (0.94, 1.22) (Figure 1). The pooled estimates from differing sensitivity analyses to assess the effect of different exposure measures did not differ substantively from this estimate (all odds ratios for these analyses were between 1.05 and 1.08).…”

Relation of Alcohol/Tobacco use with Metastasis, Hormonal (Estrogen and Progesterone) Receptor Status and c-erbB2 Protein in Mammary Ductal Carcinoma

“…However, since the end of the 1980's, a multitude of articles have been published about the fact that the regular 1 consumption of alcohol and use of tobacco represent risk factors for breast cancer (Stefani et al, 2011;CardenasRodriguez et al, 2012;de Menezes et al, 2013;Gao et al, 2013;Gou et al, 2013). Interestingly, some of the first studies actually showed a reduction of the risk of breast cancer with tobacco use (Meara et al, 1989) or alcohol consumption (Adami et al, 1988;Liu, M. et al, 2014b), or no association between smoking and breast cancer (Smith et al, 1994), further more, did not find any association between alcohol consumption and an increased risk of cancers of the lung, bladder, endometrium and ovary (de Menezes et al, 2013), and it was also observed that alcohol consumption may be inversely related to thyroid cancer. And on the other hand, in certain study suggest that cigarette smoking is associated with an elevated risk of breast cancer among former smokers in Serbia (Ilic et al, 2013).…”
