A biopsy is a diagnostic procedure in which a little tissue is removed from any part of a person’s body and then it is studied under a microscope for determining the actual cause of a disease.
Types of Biopsies
The biopsy gives the greatest certainty of diagnosis. There are different modes depending on clinical circumstances:
- Tissue biopsy
- Lymph node biopsy
- Daniel biopsy or scalene node biopsy,
- Biopsy of soft tissue mass,
- Bone biopsy of an osteolytic lesion
- Bone marrow biopsy
- Pleural biopsy
- Percutaneous lung biopsy or transmural or transpleural:
- Late or preoperative biopsy
Other types of biopsies include:
Excision biopsy: it is the complete removal of an organ or a tumor, usually without margins, which is normally performed in the operating room under anesthesia. Excision biopsy is performed for:
- The removal of lymph node isolation.
- In small breast tumors: When it is a benign tumor, the biopsy itself is therapeutic.
- In suspicious skin lesions, especially melanin: If they are benign, no further surgical treatment is required after the biopsy.
- The spleen cannot be biopsied in case of lymphoma , taking a sample of the risk of bleeding , so it is completely removed ( splenectomy ).
Intraoperative biopsy: this is obtained during an exploratory laparotomy for example in ovarian cancer.
Perpendicular Cervical Biopsy: this is done in the cervical area to determine cervical cancer.
Incision biopsy: It is the biopsy that is done to surgically remove a tumor or obtain a piece of tissue from it. This type of biopsy is used most often used in soft tissue tumors of the brain , liver , lung or kidney.
Endoscopic Biopsy: biopsy is done through an endoscope inserted through a natural orifice or a small surgical incision.
