The first CTS questionnaire focused on potential breast cancer risk factors including a comprehensive assessment of diet, alcohol use, use of hormone therapy and oral contraceptives, physical activity, menstrual and reproductive factors, family history of cancer and other diseases, exposure to electromagnetic fields, and smoking. 133,479 women responded to this questionnaire.


The second CTS questionnaire focused on exposure to secondhand smoke, updated and expanded pregnancy history, ascertained exposures to x-rays and medical radiation, collected usual diet information for a select group of new foods and beverages, and included detailed instructions for taking self-measurements of waist and hip circumferences. 


The third CTS questionnaire included detailed data on perceived stress, social support, and cognition and updated data on menopausal status, overall health, and use of oral contraceptives, menopausal hormone therapy, and other prescription and over-the-counter medications.

Our fifth questionnaire collected a comprehensive update of participants' health history, especially factors that may be related to breast cancer. The questionnaire collected data on sleep habits, oral contraceptive and hormone use, physical activities, vitamin supplements, hormone patches/creams, personal care practices, diabetes and the use of various kinds of medications. 


Our sixth questionnaire collected updates on participants' health history,  sleep habits, hormone use, physical activity, medications, and family history of cancer.
