Definitions &Translations A biopsy is a medical test commonly performed by a surgeon, interventional radiologist, or an interventional cardiologist involving sampling of cells or tissues for examination. It is the medical removal of tissue from a living subject to determine the presence or extent of a disease.The tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy.When only a sample of tissue is removed with preservation of the histological architecture of the tissue’s cells, the procedure is called an incisional biopsy or core biopsy.he tissue is generally examined under a microscope by a pathologist, and can also be analyzed chemically. When an entire lump or suspicious area is removed, the procedure is called an excisional biopsy.

Heart Disease and the Heart Biopsy A heart biopsy, also called myocardial biopsy or cardiac biopsy, is an invasive procedure to detect heart disease. It entails using a bioptome (a small catheter with a grasping device on the end) to obtain a small piece of heart muscle tissue that is sent to a laboratory for analysis.

Swelling of Salivary Gland: Causes and Treatments Sialography so that saliva flow can be seen, a dye is injected into the gland's duct. Salivary gland biopsy is the removal of a piece of tissue sample to diagnose a tumor, cyst, or Sjogren's syndrome. Fine-needle aspiration uses a thin needle to remove cells from the salivary gland to determine whether a tumor is cancerous.

Muscle Biopsy There are two different ways to perform a muscle biopsy. The most common method is called a needle biopsy. For this procedure, your doctor will insert a thin needle through your skin to remove your muscle tissue. Depending on your condition, the doctor will use a certain type of needle.

Biopsy - What to Expect A biopsy is a medical procedure that, for most types of cancer, is the only way to make a definitive cancer diagnosis, as it provides the most accurate analysis of tissue. Often, doctors will recommend a biopsy after a physical examination or imaging study, such as an x-ray, has identified a possible tumor.

Biopsy: Types of biopsy procedures used to diagnose cancer Analyzing a sample of bone marrow may reveal what's causing your blood problem. Bone marrow biopsy is commonly used to diagnose a variety of blood problems — both noncancerous and cancerous — including blood cancers, such as leukemia, lymphoma and multiple myeloma. A bone marrow biopsy may also detect cancers that started elsewhere and traveled to the bone marrow.

Prostate Cancer The result of the pathologist's analysis of the biopsy cores under the microscope is the only way to diagnose prostate cancer. The prostate biopsy technique samples many areas of the prostate but rarely the biopsy can miss small areas of prostate cancer in the prostate. Thus, if the initial biopsy results are negative but the urologist is still suspicious based on the results of the examination, the ultrasound images seen during the procedure, or the PSA, additional biopsies or tests may be recommended.

Liver Biopsy What is a liver biopsy? A liver biopsy is a test used to diagnose liver conditions. Tissue samples are removed from your liver and checked under a microscope for signs of damage or disease. A liver biopsy can tell if there are cancer cells or other abnormal cells in your liver. It can also tell how well your liver is working.

- What is a breast biopsy? A breast biopsy is a test that removes tissue or sometimes fluid from the suspicious area. The removed cells are examined under a microscope and further tested to check for the presence of breast cancer. A biopsy is the only diagnostic procedure that can definitely determine if the suspicious area is cancerous.

Diagnosis Tests and diagnosis. If your doctor suspects you have polymyositis, he or she might suggest some of the following tests: 1  Blood tests. 2  A blood test will let your doctor know if you have elevated levels of muscle enzymes, such as creatine kinase (CK) and aldolase. 3  Increased CK and aldolase levels can indicate muscle damage.

Skin Anatomy The arrector pili muscle is a source of information when evaluating a skin biopsy since it is well-innervated with autonomic nerves that control when the muscle contracts. These autonomic nerves are also visible when the skin biopsy is immunostained.

Prostate biopsy A prostate biopsy is a procedure to remove samples of suspicious tissue from the prostate. The prostate is a small, walnut-shaped gland in men that produces fluid that nourishes and transports sperm. During a prostate biopsy a needle is used to collect a number of tissue samples from your prostate gland. The procedure is performed by a doctor who specializes in the urinary system and men's sex organs (urologist).
