Is Screening for Cancer Worth While? Results from a Well-woman Clinic for Cancer Detection

Abstract

1,768 women were screened for breast and cervical cancer in the year May 1968 to April 1969. Clinical examination followed the completion of a simple questionary. Investigations included thermography and mammography of the breast and cytology of the cervical and vaginal smears. Breast cancer was detected in 15 patients (0·85% or 8·5 per 1,000) and none was aware of any abnormality though 13 of the tumours were clinically palpable. Carcinoma in situ of the cervix was found in a further eight (0·45% or 4·5 per 1,000).
