Biopsy: Types and Purpose

There are several types of biopsy which are done to inspect the diseases and germs. Know here how they are done and why.

What is Biopsy?

Biopsy is a clinical procedure performed by a physician by taking a tissue from your body to examine the signs of diseases and germs. Biopsy is not as painful as it sounds and mostly done with pain free procedures. A piece of skin, organ or tissue is removed and then sent to a lab for examining. Biopsy is helpful to diagnose various diseases or identify the cancer symptoms.

Types of Biopsy:

Punch biopsy:

A punch biopsy is performed to examine the various skin conditions. A punch biopsy is performed with a special surgical instrument to make the small hole in the skin to take out the layer’s top tissues. Before that the area is made numb by using anesthetic medication. Later on, the skin partings or wounds are put together by stiches.

Needle Biopsies:

Needle biopsy is used to remove the tissues from organs or beneath the skin. A special long needle is penetrated through the skin into the liver, bone marrow, lumps and kidney to take the sample. To lower the pain, a physician can use numbing cream or local anesthetic medication for that. It is commonly used in ultrasound scan and MRI where the physician can observe the needle is going in the right spot. The types of needle biopsy are:

  • Core Needle Biopsies
  • Fine Needle Biopsies
  • Image Guided Biopsies
  • Vacuum Assisted Biopsies

Bone Marrow Biopsy:

Bone marrow biopsy is done by a doctor if he suspects a disease in your blood. It is commonly performed with the conditions like infection, lymphoma, anemia and infection. Besides, the test is useful to check the outbreak of the cancer cells to the other parts of the body. During the biopsy, a doctor insert a long needle into your hipbone which creates mild pain as your bones can’t be numbed.

Endoscopic Biopsy:

Endoscopic biopsies are done to collect samples from the internal organs like bladder, lung and colon. A physician insert a flexible thing tube known as endoscope attached with a tiny and a light at the end, to take the images. Besides, it is attached with tiny surgical tools to collect a sample. Usually, the endoscope is entered into your body through the opening passages like mouth, rectum, urethra and nose. The biopsy takes time from 5 to 20 minutes. You may have sore throat, bloating or gas problem after going through the endoscopic biopsy.

Excisional Biopsy:

Excisional biopsy is performed by removing the entire lump of abnormal skin which may include a portion of the normal skin. Afterwards, your wounds are stitched. It is generally done as an outpatient process by using a numbing medication. A skin is removed to reach that area or sometimes, X-ray or ultrasound is performed to locate the area. It’s an hour long process.

These are the major types of biopsies to inspect the signs of diseases and bacteria in the body. You must follow your doctor guidelines and must visit him whenever he calls you or as per your follow up.
