The California Teachers Study (CTS) was founded in 1995 when 133,479 women agreed to provide information about their health and behaviors to CTS researchers.
In the years that have followed, participants have continued to provide important information about their health and lives.
Although the CTS was originally founded to study breast cancer, the data provided by participants has allowed CTS researchers to study the causes of cancer and other diseases.
The California Teachers Study is a collaborative research project managed across four partner institutions.
CTS researchers bring a wealth of experience and expertise from their respective fields. These researchers work closely with CTS research staff to better understand the complex causes of cancer.
California Teachers Study participants are a dedicated group of teachers and administrators who initially completed a self-reported health questionnaire in 1995.
In the decades that followed, these participants have continued to provide essential information about their health behaviors, family history, and experiences.
