Husband's smoking status and breast cancer risk in Japan: From the Takayama study.

The effects of smoking on breast cancer remain unclear. We assessed the associations of subjects' or husbands' smoking status with breast cancer incidence in a population-based prospective study in Japan. The subjects were 15 719 women aged 35 years or older.

Diabetes mellitus and risk of cancer in Takayama: a population-based prospective cohort study in Japan.

Diabetes mellitus (DM) has been reported to be associated with an increased risk of site-specific cancers; however, few studies have assessed associations of DM with both total and site-specific cancers in Japan. We examined the association of a history of DM with cancer incidence in a population-based prospective cohort study in Japan. A total of 14 173 men and 16 547 women over 35 years old, who completed a self-administered baseline questionnaire in 1992, were followed up for cancer incidence from September 1992 to March 2008.

Soy isoflavone intake and breast cancer risk in Japan: from the Takayama study.

The effects of soy or isoflavone intake on breast cancer need to be examined further in epidemiologic studies. We assessed the associations of soy and isoflavone intake with breast cancer incidence in a population-based prospective cohort study in Japan. Participants were members from the Takayama study, aged 35 years or older in 1992.

Soy product consumption and the risk of colon cancer: a prospective study in Takayama, Japan.

The relationship of the intake of soy products and the incidence of colon cancer was prospectively evaluated in a population-based cohort study in Japan. The total intake of soy products and isoflavones in a daily diet was estimated from a validated questionnaire administered at the baseline. The participation rate of the questionnaire was 92.

The relationship between the consumption of meat, fat, and coffee and the risk of colon cancer: a prospective study in Japan.

The risk of the development of colon cancer in relation to a western diet was studied in a community-based cohort in Japan. From 1992 to 2000, 13,894 men and 16,327 women were followed. In men, high consumption of processed meat increased the risk in comparison with low consumption (adjusted RR=1.
