An incisional biopsy or core biopsy samples a portion of the abnormal tissue without attempting to remove the entire lesion or tumor. When a sample of tissue or fluid is removed with a needle in such a way that cells are removed without preserving the histological architecture of the tissue cells, the procedure is called a needle aspiration ...

Types of biopsies include core biopsies , which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or ...
Excisional biopsies of skin lesions and gastrointestinal polyps are very common.
