[The Breast Program--25-year role of the health service].

In screening for breast cancer, the discovery of screening positive cases can be carried out either with screening mammographic examination, with breast physical examination, or with breast self-examination. The screening positive cases should be examined with diagnostic mammographic examination. In BSE-screening, one-way communication about BSE does not influence health behaviour like e.g. monthly BSE-performance, followed by self-referral to a physician if breasts change from normal. Aimed at behavioural change, two-way communication strategies are needed in comprehensive program designs. The finnish Mama Program Screening is based on delivery of the message with two-way communication and the use of specially designed Mama-calenders for follow-up of the health behaviour of the participants during the continuous program. In a cohort, exposed to the Mama Program, compliance with BSE increased from 2% to 55% monthly performance. Two percent self-referred to the diagnostic mammographic examinations arranged within public health care facilities. In a 14 years follow-up of the complying women, 20% more breast cancers were detected than expected and mortality from breast cancer was 29% less than expected in all age groups. The Mama Program Screening has been implemented in public health care in Finland on a voluntary basis as an easy and inexpensive basic screening for women in all ages. It can be implemented in different PHC and private health care systems.
