Risk of breast cancer after exposure to fertility drugs: results from a large Danish cohort study.

Background: Few epidemiologic studies have examined the association between fertility drugs and breast cancer risk, and results have been contradicting. Using data from the largest cohort of infertile women to date, the aim of this study was to examine the effects of fertility drugs on breast cancer risk overall and according to histologic subtypes.

Method: A cohort of 54,362 women with infertility problems referred to all Danish fertility clinics between 1963 and 1998 was established.

[Human papillomavirus and the risk of anogenital cancer].

Strong evidence suggests that virtually all cases of cervical cancer are caused by infection with oncognenic types of human papillomavirus (HPV). HPV is also found frequently in neighbouring anogenital epithelia and their neoplastic lesions. This review describes the general aspects of the natural history of anogenital HPV infections and summarises the evidence for an association between HPV and cancers of the uterine cervix, vulva, anus and penis.

Determinants for non-use of contraception at first intercourse; a study of 10841 young Danish women from the general population.

Based on interview data from 10841 Danish women aged 20 to 29 years, determinants for non-use of contraception at first intercourse (NU) were studied. One-fourth of the women (n = 2704) reported NU, whereas condoms and oral contraceptives were used by, respectively, 59% and 15%. NU decreased with the birth year of the first male partner (OR = 3.

[Who are the users of emergency contraception?].

Introduction: A user profile is necessary in order to direct future campaigns for emergency contraception (EC).

Material And Methods: Over a three-month period, 423 women with prescriptions for EC were consecutively entered in the study, which was carried out in four inner-city pharmacies in Copenhagen, Denmark.

Results: The median age was 24 years (range 13-50 years).

Type specific persistence of high risk human papillomavirus (HPV) as indicator of high grade cervical squamous intraepithelial lesions in young women: population based prospective follow up study.

Objectives: To investigate the role of human papillomavirus (HPV) in the development of cervical neoplasia in women with no previous cervical cytological abnormalities; whether the presence of virus DNA predicts development of squamous intraepithelial lesion; and whether the risk of incident squamous intraepithelial lesions differs with repeated detection of the same HPV type versus repeated detection of different types.

Design: Population based prospective cohort study.

Setting: General population in Copenhagen, Denmark.
