• Benign breast lesions is one of the

common diseases:

– America: 1 million women diagnosed benign

breast lesions/ year – Thailand: 73% benign breast lesions / study of

2532 patients biopsied

• Pain, discomfort in breast is sensitive

 reduce the quality of life

 Treatment? Vacuum- assisted breast

• There is a proportional correlation between the size of the

lesions and other factors such as the amount of anesthetics

used, the volume of the hematoma after the biopsy, the time

of wound removal and the size of the biopsy needle

Complications after biopsy

• The distance from the lesion to the skin surface is inversely

proportional to the size of the post-biopsy hematoma (p= 0,04).

• Vacuum-assisted breast biopsy is an effective

and safe method for removal benign breast
