Introduction : Dense breast parenchyma are reported as increasing risk of breastcancer from the previously study. The dense breasts have a role toconsider additional MRI to the screening mammogram for early detectionin women with moderately increased breast cancer risk.Objective : To assess breast parenchymal patterns of Thai women with breastcancers.Setting : King Chulalongkorn Memorial HospitalResearch design : A retrospective study.Patients : Thai women who had verified of breast cancers and had bilateralmammography in King Chulalongkorn Memorial Hospital.Methods : Seventy two Thai women with breast cancers were retrospectivelyreviewed for breast parenchymal patterns from the latest mammographybefore surgery by a skilled breast radiologist. The breast parenchymalpatterns were classified according to Wolfe’s classification (N1, P1,P2 and Dy).Results : The mean age value of 72 Thai women with breast cancers is 50 years(age range 32 - 75 years). The breast parenchymal patterns of thesewomen were 2 cases as type N1 (3%), 12 cases as type P1 (17%),26 cases as type P2 (36%) and 32 cases as type DY (44%). The P2and Dy breast parenchymal patterns are majority in 3 age-groups;30 - 39 years, 40 - 49 years and 50 - 59 years. The most frequentcancer type is invasive ductal carcinoma (66 cases, 91.7%).Conclusions : Type P2 and DY represented dense breast were the most prevalentmammographic breast parenchymal patterns in Thai women withbreast cancers.
