TL;DR: Women who were under 30 or over 50 years of age when irradiated were at greatest absolute risk for developing a second cancer, and the RR was higher among those under age 30 years at exposure than among older women.

TL;DR: It appeared that there are clear excess risks for cancers other than acute leukaemia which must be ascribed to therapy for the first cancer, especially in view of the possible under‐reporting in registry material.

TL;DR: The model proposed in this study of risk proportional to mass exposed and of risk to an individual given by the sum of incremental risks to anatomic sites appears to be applicable to a wide range of dose distributions.

TL;DR: Evidence of an association between an increased intake of nutrients, especially total fat, in both pre- menopausal and post-menopausal women with breast cancer and its consistency with other evidence, both experimental and international, suggests that it is causal.

TL;DR: A case-control study in four areas of Canada is suggestive of an increased risk of breast cancer in post-menopausal women with younger age at menarche and an increase risk with delay of age at natural menopause, and a weak association with increased height and weight as risk factors for breast cancer.
