| pubmed-article:7791232 | pubmed:otherAbstract | PIP: A population-based case control study examined the relationship between use of oral contraceptives and breast cancer among women in a cohort, focusing on women younger than 45 years old who had the opportunity for exposure throughout their entire reproductive years. Breast cancer patients and healthy control subjects were identified, the latter group by random-digit dialing, in Atlanta, Georgia, Seattle/Puget Sound, Washington, and central New Jersey. In Seattle and New Jersey, the study was confined to women 20-44 years old; in Atlanta the age range was extended through 54 years. Patients included women with in situ or invasive breast cancer newly diagnosed during the period of May 1, 1990, through December 31, 1992. In-person interviews were completed by 2203 (86.4%) of 2551 eligible patients and 2009 (78.1%) of 2571 eligible control subjects. Analyses focused on women younger than 45 years old (1648 patients and 1505 control subjects) to maximize opportunities for extended exposure. Logistic regression analyses were used to obtain maximum likelihood estimates of relative risks (RRs). Among women under 45, oral contraceptive use for 6 months or longer was associated with an RR for breast cancer of 1.3. Risks were enhanced for breast cancers occurring prior to age 35 years (RR = 1.7) with the RR rising to 2.2 for users of 10 or more years. The RR for breast cancer for those whose oral contraceptive use began before age 18 years and continued long-term ( 10 years) was even higher (RR = 3.1). The RRs observed for those who used oral contraceptives within 5 years of cancer diagnosis were higher than for those who had not, with the effect most marked for women younger than 35 years (RR = 2.0). Oral contraceptive associations were also strongest for cancers diagnosed at advanced stages. The relationship between oral contraceptives and breast cancer in young women appears to have a biologic basis rather than to be an artifact or the result of bias. | lld:pubmed |
