Risk for breast cancer development determined by mammographic parenchymal pattern

TLDR

A risk classification for breast cancer based solely on mammographic parenchymal patterns has been developed. The study reviewed mammograms of all women over 30 at Hutzel Hospital, Detroit over five years, with an average follow‑up of 2½ years. Four parenchymal pattern groups were identified, with breast‑cancer incidences of 0.1, 0.4, 1.7, and 2.2, and the patterns and identification criteria are described.

Abstract

A classification of risk for developing breast cancer has been devised based solely on the appearance of the breast parenchyma by mammography. Four groups of patients were isolated. The study encompassed a five-year period and was done by reviewing the mammograms of all women over the age of 30 who had been examined at Hutzel Hospital, Detroit. The average time of followup would be approximately 21/2 years. Four groups had an incidence of developing breast cancer of 0.1, 0.4, 1.7, and 2.2. These parenchymal patterns are described and criteria for their identification are given.
