A breast biopsy for medium-sized lesions measuring between 1 and 3 centimeters is a vital diagnostic procedure used to evaluate suspicious abnormalities detected via mammography, ultrasound, or MRI.
During the procedure, a radiologist or surgeon uses a hollow core needle, often guided by imaging, to extract multiple cylindrical samples of tissue from the specific mass.
This tissue is then sent to a pathology laboratory for detailed microscopic analysis. The pathologist determines if the lesion is benign, pre-cancerous (such as atypical hyperplasia), or malignant (cancerous), providing a definitive diagnosis essential for formulating an appropriate treatment plan.
