♦There are many different kinds of biopsies. Nearly all of them involve using a sharp tool to remove a small amount of tissue. If the biopsy will be on the skin or other sensitive area, numbing medicine is applied first. ♦Here are some types of biopsies: ★Needle biopsy:-Most biopsies are needle biopsies, meaning a needle is used to access the suspicious tissue. ★CT-guided biopsy:-A person rests in a CT-scanner; the scanner's images help doctors determine the exact position of the needle in the targeted tissue. ★Ultrasound-guided biopsy:-An ultrasound scanner helps a doctor direct the needle into the lesion. ★Bone biopsy:-A bone biopsy is used to look for cancer of the bones. This may be performed via the CT scan technique or by an orthopedic surgeon. ★Bone marrow biopsy:-A large needle is used to enter the pelvis bone to collect bone marrow. This detects blood diseases such as leukemia or lymphoma. ★Liver biopsy:-A needle is injected into the liver through the skin on the belly, capturing liver tissue. ★Kidney biopsy:-Similar to a liver biopsy, a needle is injected through the skin on the back, into the kidney. ★Aspiration biopsy:-A needle withdraws material out of a mass. This simple procedure is also called fine-needle aspiration. ★Prostate biopsy:-Multiple needle biopsies are taken at one time from the prostate gland. To reach the prostate, a probe is inserted into the rectum. ★Skin biopsy:-A punch biopsy is the main biopsy method. It uses a circular blade to get a cylindrical sample of skin tissue. ★Surgical biopsy:-Either open or laparoscopic surgery may be necessary to obtain a biopsy of hard-to-reach tissue. Either a piece of tissue or the whole lump of tissue may be removed
