Disease Description (Causes and Symptoms)

Definition: Breast microcalcifications are findings in which calcium deposits in breast tissue in the form of tiny dots (small white spots). They are mostly asymptomatic and are detected on mammography.
Pathophysiology·Causes: They form when calcium is deposited in the ducts or lobular tissue. Causes include various factors such as early breast cancer (especially ductal carcinoma in situ/DCIS), previous breast inflammation or infection, trauma (severe bruising), and abnormalities in the discharge of mammary gland secretions.
Clinical significance: Microcalcifications themselves do not cause symptoms, but certain patterns on imaging (such as tightly clustered, irregular, linear, or branching patterns) may be associated with cancer, so a biopsy may be necessary. Reports indicate that approximately 20% of microcalcifications identified during examinations are diagnosed as cancer.
Symptoms: Mostly asymptomatic (not palpable). Rarely, breast pain or a feeling of a lump may occur, but symptoms caused by the calcifications themselves are uncommon.

Treatment Methods

General principles: Microcalcifications themselves are an imaging finding rather than a disease, so if the calcifications are considered benign, no separate treatment is necessary.
Management according to imaging findings
- Suspicious findings (clusters, fine and irregular forms, linear/branching forms, etc.): A biopsy (usually a stereotactic (image-guided) core needle biopsy or, if necessary, an excisional biopsy) is performed to determine whether the lesion is malignant.
- Benign findings: Regular imaging follow-up (the examination interval may be once a year depending on the clinical situation or every 6 months according to the doctor's recommendation).
If diagnosed as breast cancer: Standard breast cancer treatment (surgery, radiation therapy, chemotherapy, hormone therapy, targeted therapy, etc.) is performed according to the stage and histopathological findings.
Lifestyle management·Precautions: Undergo regular breast screening (mammography according to age and risk level), perform breast self-examinations, and consult medical staff immediately if there are changes in breast symptoms. Inform medical staff if an examination is needed during pregnancy or breastfeeding.

Preparation items (things that may help with the consultation if brought)

A list of currently used medications (including hormone medications and anticoagulants).
Results of previous breast examinations (previous mammography/ultrasound films or radiology reports) — comparison with previous images is important.
Family history (breast cancer, ovarian cancer, etc. in immediate family members) and personal medical history (breast surgery, biopsy, breast inflammation, breast trauma, etc.).
Menstrual cycle information (if menstruating, this can help coordinate the examination schedule).
A record of symptom changes (breast pain, discharge, a palpable lump, etc.).

Example questions to ask when visiting the outpatient clinic

Recent breast imaging (when was it performed, and what were the results?)
Family history·Genetic risk (whether testing for BRCA status is necessary, etc.)
Possibility of pregnancy or breastfeeding status (impact on examinations and treatment)

How likely is it that this finding is cancer?
Why is additional testing (a biopsy) necessary, and what are the testing method and risks?
What will the follow-up schedule be after the examination?
Are there any preventive measures or lifestyle changes I should follow?
What are the risks of complications and the expected recovery period after a biopsy (or surgery)?

What does the pattern of the calcifications seen on imaging (e.g., clustered, linear·branching, dispersed, etc.) mean? How much does this pattern increase the risk of cancer?
I was told that a definitive diagnosis cannot be made based on the current imaging findings alone. Which test do you recommend, a stereotactic core needle biopsy or a surgical excisional biopsy? What are the advantages and disadvantages of each option?
