Normal labeled

Young adult

• In young women the breast is extremely dense . 

• Hence it is difficult to distinguish cancer from normal dense glandular tissue in young women.

Cancer Breast

• Primary:  

  • Mass

    • Asymmetric density

    • A spiculated mass is the most common mammographic appearance.

  • Calcifications 

    • Micro calcifications may be seen on mammography in at least 30% of cases of invasive carcinoma. 

    • They are 1 mm or less and sand like

    • The calcifications represent necrotic debris

  • Developing density

• Secondary:  

  • architectural distortion

  • skin thickening or retraction

  • nipple and areolar thickening

  • abnormal ductal patterns

  • lymphadenopathy.   

  • venous engorgement

  • asymmetry of the breast tissue.   

Fibroadenoma

• A fibroadenoma appears as a well circumscribed mass with well-defined borders

• Its borders are smooth and round, oval or nodular

• They are frequently multiple and bilateral

• It typically has the appearance of a dense, popcorn-like calcification on mammogram
