VABB vacuum-assisted breast biopsies allow large enough tissue samples to be obtained for accurate diagnosis and complete removal of the lesion under ultrasound guidance, with only 1 needle puncture. The advantage of VABB is that it completely and accurately captures the lesion, avoids underdiagnosis, and reduces the mismatch between imaging and histology.
1. What is a breast biopsy?
Breast biopsy is a procedure to remove a sample of breast tissue to send to the pathology room for histological and cytological examination of breast lesions. Breast biopsy is a method to accurately evaluate the suspected breast tissue to determine whether breast cancer cells are present. There are many techniques for breast biopsy.
Breast biopsies provide a sample of breast tissue that doctors use to identify and diagnose cell abnormalities that cause breast lumps, abnormal changes in the breast, or suspicious findings on mammograms or on breast ultrasound. The results of your pathology will help your doctor decide if you need surgery or other treatment.
1.1 When to do a breast biopsy?
Conduct a breast biopsy in case:
The doctor examines a lump or thickening of the breast, and the doctor suspects breast cancer. Mammogram showing suspected breast lesion Ultrasound showing suspected lesion Breast MRI showing suspected lesion Unusual changes in nipple and areola including rough, scaly changes , skin retraction or red nipple discharge. 1.2 What to prepare before a breast biopsy?
Need to inform the doctor about:
Allergies Use of Aspirin 7 days ago Is taking anticoagulants Having difficulty lying on the stomach or lying down for a long time

1.3 Methods of Breast Biopsy
The doctor will decide on a breast biopsy technique based on the size, location and other characteristics of the mammary gland abnormality.
Breast biopsy techniques include:
Fine-needle breast biopsy Needle core biopsy Localized needle biopsy Ultrasound-guided core needle biopsy Surgical biopsy In these techniques, the gold standard is surgery. Full biopsy of the suspected lesion. However, breast biopsy surgery leaving surgical scars is inevitable.

2. Purpose of vacuum-assisted breast biopsy VABB
Recently, a less invasive method, leaving no scars, is a core needle biopsy under the skin guided by imaging tools, which has gradually been widely applied for the diagnosis of palpable lesions. visible and invisible. Although core needle biopsies are highly sensitive, the disadvantage of this technique is its underdiagnosis, which affects the treatment of atypical ductal hyperplasia, papillary lesions, and other conditions. fibrous epithelial damage.
Therefore, vacuum assisted biopsy (VABB) technique was born to overcome these weaknesses. The VABB allows for a tissue sample large enough for accurate diagnosis and complete removal of the lesion under ultrasound guidance, with only one needle puncture. The advantage of VABB is that it completely and accurately captures the lesion, avoids underdiagnosis, reduces the mismatch between imaging and histology, and reduces the need for re-biopsy. , and reduce the chances of the tumor growing back.

3. In what cases does a VABB vacuum-assisted breast biopsy?
In the future, VABB may become the routine choice for breast biopsies. VABB may be recommended in patients who have an indication for core biopsy but want to completely remove the lesion such as: Patients who do not have conditions for regular follow-up, patients who are planning to become pregnant, patients with damaged lesions. The lesion increased in size during the follow-up period, the patient had subjective symptoms and pain associated with BIRADS 3-4A lesions.
Astral margin lesions are smaller than 5mm, it can sometimes be difficult to obtain biopsies with standard core biopsy. Therefore, VABB helps to remove the entire lesion for more accurate histology.
In some cases, biopsy of a new large tissue sample can help differentiate between fibrous changes, atypical lesions, and carcinoma in situ. Therefore, a mixed solid-tissue cyst is considered a suspect lesion and needs to be biopsied, or removed by VABB.
VABB helps biopsies diffuse microcalcifications for better results than core needle biopsies.
Breast papilloma can be detected by color Doppler ultrasound. If a papilloma lesion is suspected, it is in most cases benign, however in some cases it is difficult to distinguish from intraductal carcinoma. turned into papillary carcinoma, so we need to biopsy the whole lesion. Full lesion biopsies can be performed by needle placement or by VABB.
Lesions near the nipple, near the chest wall, near the skin, or the axillary fossa are recommended for VABB rather than core needle biopsy because of the possibility of better and safer tissue sampling.
When performing core needle biopsy failed, it is possible to switch to VABB biopsy to better cut the tissue sample. Therefore, VABB is performed when tissue or cell samples obtained with FNA or needle core are not sufficient for diagnosis.

In the treatment:
Recently, the FDA advocated the use of VABB in the treatment of benign lesions.
Tumors that the patient feels, although it is likely to be benign, is always worrying for the patient, especially in patients with familial risk factors for breast cancer. Many patients have requested surgical resection of potentially benign tumors. In these situations, VABB is an integrated option. Benign tumors 2.5-3 cm can be completely removed with VABB without scarring.
Many studies have successfully performed complete removal of benign tumors (usually fibroadenomas with an 8-11 gauge needle under ultrasound guidance.
VABB also helps determine the possibility of preservation. nipples in patients with invasive and in situ breast cancer when they have a desire to preserve the breast
