SummaryThe association between soya foods and breast cancer risk was investigated in a prospective study of 34 759 women in Hiroshima and Nagasaki, Japan. Women completed dietary questionnaires in 1969–1970 and/or in 1979–1981 and were followed for incident breast cancer until 1993. The analysis involved 427 cases of primary breast cancer in 488 989(More)

A prospective cohort of 1.3 million middle-aged women was used to examine these relationships. During 7.7 million women-years of follow-up, a total of 1563 women were diagnosed with a primary(More)

BACKGROUND Postmenopausal women who use hormone-replacement therapy (HRT) containing oestrogen alone are at increased risk of endometrial cancer. To minimise this risk, many HRT users who have not had a hysterectomy use combined oestrogen-progestagen preparations or tibolone. Limited information is available on the incidence of endometrial cancer in users(More)
Uganda offers a unique setting in which to study the effect of human immunodeficiency virus-1 (HIV-1) on cancer. HIV-1 is prevalent there, and cancers which are known to be HIV-associated, such as Kaposi's sarcoma and Burkitt's lymphoma, are endemic. Adults residing in Kampala, Uganda, presenting with cancer in city hospitals were interviewed and had an HIV(More)
BACKGROUND Little information is available on how the risk of breast cancer associated with the use of hormone therapy for menopause varies by histological type. We aimed to describe such associations for eight histological types of breast cancer. METHODS Analyses are based on 1 031 224 postmenopausal women recruited in 1996-2001 into a nationwide UK(More)
