Other Diagnostic Studies
The only certain method to approve the presence of breast malignancy is breast lump biopsy [1]
There are three types of biopsy:
Core-needle biopsy[1]
- Ultrasound guided-core needle biopsy[3]
- The needle is guided by use of ultrasound and patient lies on back or side
- Highly sensitivity and specificity
- Choice method for breast tissue sampling
- Stereotactic-guided core-needle biopsy
- The needle is guided by use of x-ray and computer and patient lie on stomach
- Choice method for mammograohically suspicious breast lumps which are occult in ultrasound[4]
- MRI-guided core-needle biopsy
- The needle is guided by Magnetic resonance imaging
- Freehand core-needle biopsy
- Usually used for breast lumps which can be felt by hand on breast tissue
Core-needle biopsy has lower risk of complications such as bleeding, bruising and infection
Open surgical biopsy[1]
- Perform under general anesthesia
- If core-needle biopsy is unavailable due to location of breast lump, open surgical biopsy is required
- In patients with high risk of cancer is recommended
- 1-2 inch cut on breast tissue for breast lump removal
- Higher risk of complications (bruising, bleeding, pain and infection)
Fine needle biopsy (FNA)[2]
- Performed by small needle (21-25 gauge)
- Regarding to small amount of breast tissue, FNA is considered as controversial method for breast lump diagnosis
- Performed for large and symptomatic breast cysts or imaginary abnormalities
- Complications of FNA include bruising, bleeding, pain, infection and pneumothorax;if needle goes deep inside the chest)
- Due to inadequate tissue or nondiagnostic results, FNA has lower rate of diagnosis rather than core-needle biopsy
- FNA advantages
- Cost-effectiveness
- Less invasive method
- Suitable for patient under anticoagulant therapy
- Appropriate to sample axillary tissue
- FNA follow-up
- Non-bloody fluid/resolved cyst
- Ultrasound follow-up to reassure the cyst has been resolved
- No more follow-up
- Bloody fluid/ persistent cyst
- Refer to a surgeon for open surgical biopsy
- Non-bloody fluid/resolved cyst
