The procedure involves the removal of tissues from the suspected body part(s) and test by a pathologist using a microscope to find out if the cells in the tissue are damaged or have abnormalities.
The tissue sample can be taken from the suspected part of the body - be it an external or an internal part ( an organ ). Some of the common areas are skin, breast, cervical, prostate gland, and also the liver, thyroid, stomach, large bowel, muscles, etc. Biopsies can be of different types. There may be the need for a small amount of tissue that can be removed using a needle, or it may involve removing an entire lump or nodule through a surgical method.
If the internal organs are suspected, the exact area from where the tissue sample is to be collected is decided using the imaging guidance. Endoscopy and Colonoscopy are mostly used to view and remove the tissue sample and polyps(the lumps in the lining of organs) of the esophagus, stomach, and the colon.
If the tissue sample is to be taken externally the area of the skin is disinfected and put under local anesthesia before surgically removing the tissue sample.
