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
  • Percutaneous
  • 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.
