Biopsy

What is Biopsy?

A biopsy is a process to take a sample of your body’s cells or tissue so that it may be examined in a lab. If you exhibit specific signs and symptoms or if your doctor has found a problem area, you might be required to have a biopsy. Whether you have cancer or another illness can be determined via a biopsy.

Although imaging tests like CT scans and MRIs are useful for finding lumps or abnormal tissue, they are unable to distinguish between cancerous and non-cancerous cells on their own. The only way to diagnose the majority of malignancies is to conduct a biopsy to gather cells for further in-depth analysis.

What is the use of a Biopsy?

Most typically, biopsies are performed to check for cancer. But biopsies can also be used to diagnose numerous other illnesses. A biopsy is typically performed to identify a problem or to establish the most effective course of treatment. Anytime there is a crucial medical question that a biopsy might help resolve, it might be advised. Just a few instances are shown below:
  • A tumour or lump that could be breast cancer is visible on a mammogram.
  • Melanoma could be the cause of a skin mole that recently changed shape.
  • Determining whether cirrhosis is present in a person with chronic hepatitis is crucial.
  • In rare circumstances, a biopsy of tissue that appears normal may be taken. This can assist in monitoring the spread of cancer or the rejection of a transplanted organ.

What are the different types of Biopsies?

A Needle biopsy: The majority of biopsies are needle biopsies, in which the problematic tissue is accessed using a needle.
A CT-directed biopsy: The images from the CT scanner are used by doctors to pinpoint the precise location of the needle in the desired tissue while the patient is lying still inside the machine.
An ultrasound-guided biopsy: An ultrasound scanner aids in the physician’s needle placement within the lesion.
A bone biopsy: A bone biopsy is performed to check for bone cancer. An orthopaedic surgeon or the CT scan method can be used to do this.
Biopsy of the bone marrow: In order to extract bone marrow, a sizable needle is inserted into the pelvis bone. This can find blood disorders like lymphoma or leukaemia.
Renal biopsy: A needle is put into the kidney through the skin on the back, similar to a liver biopsy
A liver biopsy: The liver tissue is extracted by injecting a needle through the belly skin into the liver.
An aspiration biopsy: The material is extracted from the mass using a needle. This straightforward process is also known as fine-needle aspiration..
Testicular biopsy: The prostate gland is sampled using several needles at once. A probe is introduced into the rectum to the prostate.
Skin biopsy: The most common type of biopsy is a punch biopsy. A circular blade is used to obtain a cylindrical sample of skin tissue.
Surgical biopsy: To take a biopsy of difficult-to-reach tissue, open or laparoscopic surgery may be required. It is possible to remove either a little portion of the tissue lump or the entire mass.
