Cigarette smoking has been identified as a risk factor for colon cancer, however, much less is known about the association between cigarette smoking and rectal cancer. The purpose of this article is to evaluate the associations between rectal cancer and active and passive cigarette smoking and other forms of tobacco use. We also evaluate how genetic variants of GSTM-1 and NAT2 alter these assoc...

Recent studies suggest that both active and passive smokers have an increased risk of breast cancer compared with women who have never been either actively or passively exposed. Data on lifetime active and passive smoking were collected in 1999-2000 from 468 predominantly premenopausal breast cancer patients diagnosed by age 50 years and 1,093 controls who had previously participated in a Germa...

The aim of this study was to develop more accurate measures of self reported active exposure to cigarette smoke. DESIGN Mail survey in 386 smokers, retest at one month in 94 participants (24%), analysis of saliva cotin...

This case-control analysis presents odds ratios for active and passive cigarette smoke exposure and cervical intraepithelial neoplasia of levels II and III (CIN II and CIN III) while controlling for confounders. From 1987 to 1988, 103 biopsy-conformed incident cases of CIN II or III and 268 controls with normal cervical cytology were enrolled. Seventy % of cases were cigarette smokers, while on...

risk analysis is an important technique to estimate impacts on the environment for adopting effective measures to avoid risks. this field study was conducted to investigate the risk of brick kiln (bk) smoke on the shoots of acacia arabica. different phenotypic parameters including morphology and growth of shoots and epidermal imprints of the leaves were studied in the vicinity of a brick kiln s...
