[Diagnostic performance of mammography in patients with clinically impercetible tumors. Analysis of 1005 tumors]. / Rendimiento diagnóstico de la mamografía en pacientes con lesiones clínicamente ocultas. Análisis de 1005 lesiones.

UNLABELLED: Breast cancer is an important public health problem. Early diagnosis is the only method of efficient secondary prevention in the control of the illness as it permits rapid and effective treatment. The objective of this study was to carry out a methodical analysis that would enable us to increase the diagnostic performance of the mammogram and to diminish the number of unnecessary surgical biopsies. MM: We selected impalpable mammary tumors in patients with radiological suspicion of breast cancer, on which surgical biopsy by harpoon had been practiced in the Lozano Blesa Hospital, Zaragoza, between October 1991 and January 2005. RESULTS: We analyzed a total of 1005 tumors in 965 patients, with an average age of 57 years. In our series of 1005 tumors, 40% were PVV. CONCLUSIONS: The diagnosis of radiological suspicion and the indication for biopsy or mammographic control are subjective and personal appreciations, but based on the systematic analysis of radiological signs of incipient tumors. This analysis enables us to establish a cut-off point to include the tumors in BIRADS.
