There are many different types of biopsies. Nearly all involve using a sharp instrument to remove a small amount of tissue. If the biopsy is to be performed on the skin or another sensitive area, numbing medication is applied first. Biopsy types can be listed as follows:

  • Needle biopsy: Most biopsies are needle biopsies. That is, a needle is used to access suspicious tissue.
  • CT-guided biopsy: The patient lies in a CT scanner. The scanner’s images help doctors determine the exact position of the needle in the targeted tissue.
  • Ultrasound guided biopsy: The ultrasound scanner helps the doctor guide the needle into the lesion.
  • Bone biopsy: It is used to look for bone cancer. This can be done by a CT scan technique or by an orthopedic surgeon.
  • Bone marrow biopsy: A large needle is used to collect bone marrow and enter the pelvic bone. With this procedure, blood diseases such as leukemia or lymphoma can be detected.
  • Liver biopsy: Liver tissue is captured by injecting a needle into the liver through the skin on the abdomen.
  • Kidney biopsy: Similar to a liver biopsy, a needle is injected into the kidney through the skin on the back.
  • Aspiration biopsy: A needle draws material from a mass. This simple procedure is also called fine needle aspiration.
  • Prostate biopsy: Multiple needle biopsies are taken from the prostate gland at the same time. A probe is inserted into the rectum to reach the prostate.
  • Skin biopsy: It uses a circular blade to take a sample of skin tissue.
  • Surgical biopsy: Open or laparoscopic surgery may be required to biopsy hard-to-reach tissue. A piece of tissue or the entire piece of tissue may be removed.

  • If necessary, the doctor closes the opening in the skin with stitches or adhesive tape.

How is Thyroid Biopsy Done?

Although it varies depending on the type of research, it is usually done by carefully inserting a thin needle into the thyroid nodule. The needles used are smaller or the same size as the needles used to draw blood. Most often, ultrasound is used to find the tip of the needle.
