Fine needle aspiration (FNA) and core biopsy
Abnormal breast tissue is usually detected by physical examination, ultrasound or mammography. However, imaging tests can’t always differentiate benign lesions from cancer, and so FNA and core biopsy are used to define the true nature of abnormal areas found on ultrasound or mammography.
For FNA a fine needle is inserted under ultrasound or x-ray guidance into the abnormal area, whereby the cells are aspirated for viewing under a microscope. Some solid lesions may benefit from core biopsy. FNA’s and core biopsy’s are carried out by a speciality trained Radiologist, and will we have an expert pathologist onsite during these procedures to ensure an adequate sample has been obtained.
