Research linking breast cancer and secondhand smoke

Prevalence of rules prohibiting home and workplace smoking correlates with state-specific breast cancer outcomes : an ecologic analysis

Authors predict that if there is a causal association between exposure to secondhand smoke (SHS) and breast cancer, then breast cancer incidence and mortality rates would be lower in states with higher numbers of women who have never smoked with smoking restrictions at home and at the workplace.

Smoking (active and passive), N-acetyltransferase 2, and risk of breast cancer

This Canadian population-based-case-control study found an increased risk of breast cancer among women who never actively smoked with a long history of secondhand smoke exposure and with NAT2 slow acetylators. Also, there was an odds ratio (OR) of 1.34 among women who actively smoked for more than 20 pack-years; however, the risk was higher among those with NAT2 fast acetylators.

Evidence secondhand smoke causes breast cancer in 2005 stronger than for lung cancer in 1986

Measures the strength of evidence from epidemiological research of secondhand smoke from the finding of the 1986 US Surgeon General report that secondhand smoke causes lung cancer with the 2005 California Environmental Protection Agency’s (CalEPA) similar conclusion on breast cancer in mainly younger premenopausal women.

Smoking increases the risk of breast cancer [poster]

A woman with tobacco-stained fingers is seen performing a breast exam. Readers are reminded that smoking and secondhand smoke increase the risk of breast cancer, especially in women under 50 years of age. The back of the poster investigates the relationship more closely by discussing the scientific evidence.

Accumulating evidence on passive and active smoking and breast cancer risk

The risk of breast cancer related to secondhand and current smoking was investigated, in addition to risk heterogeneity among studies. Studies implementing comprehensive second hand smoke exposure assessments provide that secondhand smoke and active smoking are risk factors for premenopausal breast cancer.

Active and passive smoking and breast cancer risk in middle-aged Japanese women

This paper concludes that tobacco smoking increases the risk of breast cancer in premenopausal women.

Smoking (active and passive) and breast cancer : epidemiologic evidence up to June 2001

Tobacco smoke contains known carcinogens, and is responsible for many types of cancer. This paper examines the effect of active and passive smoking on the development of breast cancer in women. The focus of this paper is on different studies that have been taken regarding smoking and breast cancer. Recommendations are made to improve these different investigations.

Passive smoking exposure and female breast cancer mortality

An analysis of women exposed to environmental tobacco smoke (ETS) from their husbands did not demonstrate an association between breast cancer mortality and ETS. However, an increased risk of breast cancer mortality was observed for women who married a man who smokes before the age of 20, but this was not statistically significant.

Breast cancer and active and passive smoking : the role of the N-acetyltransferase 2 genotype

This study found the associations of both passive and active smoking with breast cancer appear stronger in fast than in slow N-acetyltransferase 2 (NAT2) genotypes.

Passive and active smoking and breast cancer risk in Canada, 1994-97

Using Canadian data, the authors illustrate that both passive and active smoking can increase the risk of developing breast cancer in premenopausal women. The risk is increased to a lesser extent for postmenopausal women. Passive smoking includes residential and/or workplace exposure.
