Introduction: The aim of this study was to examine whether screening exposure status, defined as detection mode (screening, interval or symptomatic) combined with breast cancer screening attendance prior to diagnosis, had any additional value over detection mode in predicting breast cancer survival. We also assessed the effect of hormone replacement therapy (HRT) on the association of detection mode with breast cancer survival.
Methods: We analysed and compared the associations of both screening exposure status and detection mode with 5-year breast cancer survival on a cohort of 3013 breast cancer patients, aged 50-74 years in Sweden.
Introduction: Menopausal hormone therapy (MHT) is a well-established factor in endometrial carcinogenesis, and therefore, could have prognostic implications. We investigated the effects of ever use of MHT on tumour grade and depth of myometrial invasion and 5-year relative survival in postmenopausal endometrial cancer patients.
Materials And Methods: We used a nationwide, population-based case-case design, of 683 Swedish women aged 50-74 years diagnosed with endometrial cancer during 1994 to 1995, followed up to 5 years after diagnosis.
Breast cancer incidence after hormonal infertility treatment in Sweden: a cohort study.

January 2009
Objective: To assess the impact of infertility treatment with causes of infertility on incidence of breast cancer.
Study Design: Historical prospective cohort study of 1135 women attending major university clinics for treatment of infertility in Sweden, 1961-1976. Women were classified as users of clomiphene citrate or gonadotropins, or a combination of both therapies.
Introduction: Hormonal factors are implicated in tumor progression and it is possible that factors influencing breast cancer induction could affect prognosis. Our study investigated the effects of menstrual risk factors on tumor characteristics and survival in postmenopausal breast cancer.
Methods: We used a nationwide, population-based, case-case design of 2,640 Swedish women who were 50 to 74 years old and had postmenopausal breast cancer during 1993 to 1995.
