A bone biopsy is a procedure in which bone samples are removed to find out if cancer or infection or other abnormal cells are present. A bone biopsy involves the outer layers of bone, unlike a bone marrow biopsy, which involves the innermost part of the bone. Bone biopsy should as rule be done after all necessary imagings performed.
There are four main types of skin biopsies: shave biopsy, punch biopsy, excisional biopsy, and incisional biopsy. The choice of the different skin biopsies is dependent on the suspected diagnosis of the skin lesion. Like most biopsies, patient consent and anesthesia (usually lidocaine injected into the skin) are prerequisites. [citation needed]
Excisional biopsy involves surgically removing the suspicious area of the breast to examine it under the microscope for diagnosis. One method is wire-guided (or wire-localized) excisional biopsy, where a wire is inserted into the breast and repeatedly imaged using breast ultrasound or mammography until the technician sees that the tip is ...
The loop electrosurgical excision procedure (LEEP) is one of the most commonly used approaches to treat high grade cervical dysplasia (CIN II/III, HGSIL) and early stage cervical cancer discovered on colposcopic examination. In the UK, it is known as large loop excision of the transformation zone (LLETZ). It is considered a type of conization. [1]
A biopsy is a small piece of tissue removed primarily for the purposes of surgical pathology analysis, most often in order to render a definitive diagnosis. 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 ...

Lymph node biopsy is a test in which a lymph node or a piece of a lymph node is removed for examination under a microscope (see: biopsy). The lymphatic system is made up of several lymph nodes connected by lymph vessels. The nodes produce white blood cells (lymphocytes) that fight infections. When an infection is present, the lymph nodes swell ...
The sampling and biopsy considered together are called fine-needle aspiration biopsy (FNAB) or fine-needle aspiration cytology (FNAC) (the latter to emphasize that any aspiration biopsy involves cytopathology, not histopathology). Fine-needle aspiration biopsies are very safe for minor surgical procedures. Often, a major surgical (excisional or ...
