Description
A biopsy is a medical test where a small sample of tissue is taken from the body to examine under a microscope. It helps detect the presence of diseases, including cancer, infections, or inflammatory conditions.
How the Test is Done?
A biopsy can be performed using various techniques, depending on the location of the tissue. These methods include needle biopsy (using a needle to extract tissue), excisional biopsy (removing a whole lump or abnormal area), or endoscopic biopsy (using a tube with a camera to access internal organs). The sample is then analyzed in a laboratory.
Preparation Required
Preparation depends on the type of biopsy. For needle biopsies, minimal preparation is needed. For others, such as endoscopic biopsies, fasting for a few hours before the procedure might be required. Your doctor will give you specific instructions.
Significance of the Results
Biopsy results help in diagnosing conditions like cancer, infections, or other tissue abnormalities. A positive result may indicate the presence of abnormal or diseased cells, while a negative result usually suggests the tissue is normal. The findings are critical for deciding further treatment options.
