Click on the fibroadenoma in the image above:

Here is a small, round fibroadenoma of the breast, a benign neoplasm most commonly diagnosed in younger women of reproductive age. The blue dye was injected during a radiographic procedure to mark the location of the neoplasm so the surgeon could find and remove it. Neoplasms this small may be difficult to detect. Imaging techniques such as ultrasound or mammography may aid in diagnosis.
