Brief Summary:
To evaluate if there is any imaging characteristic of breast cancers in women younger than 40 years of age
Detailed Description:
In Western countries breast cancer is the most commonly diagnosed cancer in women and breast cancer screening using mammography has reduced breast cancer mortality by 18-29 In Taiwan breast cancer is the second most common cancer in women and the Bureau of Health Promotion Department of Health has started breast cancer screening using mammography in women between 50 and 69 years old since 2002 between 40 and 49 years old since early 2004 However young women at 20 to 39 years of age have never been enrolled in the mass screening mammography program because of their relatively young age and mammographic findings of breast cancer in young women were seldom reportedSome authors found out that breast cancer in young women is more advanced and more often presents with a mass has higher grade more extensively proliferating and vessel invading disease when compared with those in older age groups Most intraductal carcinomas 80 present as clustered microcalcifications on mammograms and the sensitivity of mammography can be reduced in younger denser breasts Given these mammography seems not to be a proper diagnostic tool for breast cancer women at a younger age However this presumption needs to be clarified since there are neither definite documented facts regarding breast cancer manifestation of young women on mammograms nor documented sensitivity and false-negative rate of mammography in detecting of breast cancer among young women at whom mammography is seldom used to be a diagnostic imaging tool Our study is conducted to analyze the mammographic findings of breast cancers in young women between 20 and 39 years of age regarding tumor size location major finding type pathology type and grade We will compare all of the above issues between younger age group and older age groups 40 to 49 and 50 to 69 years oldThe breast ultrasound findings of the breast cancer among young women will be also compared with their corresponding mammographic findings regarding the sensitivity specificity false-negative rate and accuracy
