“…The pooled RR for exclusive use of permanent dye was 1.00 (95% CI, 0.94-1.05) and was 0.99 (95% CI, 0.89 to 1.11) for intensive exposure (TABLE 2). There was no substantial difference in pooled RRs This was explained mainly by the result of 1 population-based casecontrol study 32 with an RR of 8.62 and a wide 95% CI, which might be considered as an influential point.

“…Six studies [5,8,[11][12][13]20] reported oral contraceptive use as a risk factor for breast cancer in our study. The result is consistent with other early meta-analysis.…”

“…Thus, there were a total of 15 potential independent studies for analysis, which are listed in Table 1. Fifteen studies [3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] were included in the meta-analysis on the association between reproductive factor, oral contraceptive use, breast-feeding and breast cancer risk. According to the summary OR based on two identified reproductive factors, including number of full-term pregnancy≥1 and menopausal age > 50 yr, oral contraceptive use was associated with the increase in breast cancer risk; however, the summary OR based on breastfeeding indicated no association with breast cancer risk ( Table 2, Fig.…”

The authors performed a meta-analysis of casecontrol studies that addressed whether reproductive factors and oral contraceptive use were associated with breast cancer by searching the MEDLINE, PubMed, Proquest, Embase, ScienceDirect, African Healthline, BMJ Health Intelligence and Chinese Periodical net databases for all English-language and Chinese-language papers published from A total of 15 studies calculating pool ORs indicated that menopausal age > 50 yr [odds ratio (OR), 1.39; 95% confidence interval (CI), 1.22-1.57] and oral contraceptive use (OR, 2.12*, "*": summary OR was adjusted; 95% CI, 1.24-3.62) were correlated with the increase in breast cancer risk while the summary OR based on number of full-term pregnancies≥1 (OR, 0.63*; 95% CI, 0.60-0.68) and breast-feeding (OR, 0.76; 95% CI, 0.64-0.90) indicated no association with breast cancer risk. The correlation was statistically significant. Menopausal age > 50 yr and oral contraceptive use are positively correlated with an increase in breast cancer risk while breast-feeding and number of full-term pregnancies≥1 are protective factors.

“…A total of 11 case-control studies (7, 24–34) and four cohort studies (16, 18–20, 35) have investigated the relationship between personal hair dye use and risk of breast cancer (Table 2). Nearly all of the studies have yet to suggest a conclusive no association between breast cancer risk and exposure to hair dyes with the exception of one case-control study (34).…”
