Abstract
I underwent training in breast cancer mass screening and mammography techniques in Finland from February 2nd to March 29th, 1994.
A nationwide mammography screening program was started in Finland in 1987. Screening covers women aged 50-59 years. Personal invitation letters are sent, and two-view (craniocaudal and medio-lateral oblique) screen-film mammography is performed as the only screening examination at two-year intervals.
The quality control of the mammography unit and imaging is guided by law and checked by the Medical Physicist at the Finnish Center fro Radiation and Nuclear Safety on an irregular basis, but at least once every 5 years.
