Participants were invited for 3 rounds of clinical breast examination, conducted 3-years apart. Screening was conducted by health workers trained to perform clinical breast examination for early detection of cancer. Women with abnormal referable lesions underwent CBE by a trained clinician and those women with a confirmed breast lump or any other breast abnormality warranting further investigations were evaluated by triple-testing involving expert physical examination, diagnostic mammography with or without ultrasonography and fine needle aspiration cytology (FNAC) or core biopsy or excision biopsy. Those with confirmed breast cancer were referred for appropriate treatment with surgery, radiotherapy, and/or chemotherapy.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Breast Cancer Death Rate	Information on all deaths were collected from the municipal and district death registers, hospital medical records, death records of churches and mosques, hospital visits by the population cancer registry staff and by project health workers. Cancer cases were coded by the ICD-O 3rd edition codes and cause of death was coded using ICD-10 by the registry and project staff blinded to study group allocation. Deaths were attributed to breast cancer if the patient had histologically or clinically confirmed breast cancer, lymph nodes or distant metastasis at the time of death or had died due to complications of breast cancer treatment.	14 years
Primary	Breast Cancer Incidence	Information on incident breast cancer cases were obtained from the Trivandrum population-based cancer registry, hospital cancer registry of the RCC and medical records departments of other hospitals treating breast cancer patients. Collection of information was blinded to study group assignment of cases. The staging of breast cancers was done according to the UICC TNM staging system.	14 years
