What happens is they have a ultra sound to see where it is exactly and they mark they have a tendency to get more tissue with a needle biopsy they can extract a better piece of tissue sample sometimes they can get the whole tissue sample this way

What procedures are involved in needle biopsy?
aspiration biopsy (using a fine needle) and large-core needle biopsy. Either of these may be called a percutaneous needle biopsy. Percutaneous refers to a procedure done through the skin.

No. A lung needle biopsy is used to pull a sample of tissue from the lungs for testing. A lung needle biopsy should NOT be done with someone who has Emphysema.
What type of preparation is needed for a thyroid fine needle biopsy?
If a needle biopsy is done, no special preparation is needed. If a large needle biopsy is being done, the doctor may order some tests to determine the clotting ability of the blood.
Where is a fine needle aspiration biopsy done?
It can be done in a doctor's office, clinic, or hospital
What is the medical term meaning biopsy is done with a large gauge needle inserted into the tumor to obtain several long pieces of tissue?
Fine needle aspiration is done with a large-gauge needle.
How is a fine needle aspiration biopsy of the thyroid done?
This is done by extracting cells from the thyroid using a very fine needle. It is usually done under local anaesthetic and then the cells are sent to a cytopathologist to be analysed.
What is the purpose of a bone biopsy?
There are several different types of biopsies.A needle (percutaneous) biopsy removes tissue using a hollow tube called a syringe. A needle is passed through the syringe into the area being examined. The surgeon uses the needle to remove the tissue sample. Needle biopsies are often done using x-rays (usually CT scan), which guide the surgeon to the appropriate area. An open biopsy is a surgery that uses general anesthesia. This means you are asleep and pain-free during the procedure. The procedure is done in a hospital operating room. A surgeon makes a cut into the affected area, and the tissue is removed. Closed biopsy uses a much smaller surgical cut than open biopsy. A small cut is made so that a camera-like instrument can be inserted. This instrument helps guide the surgeon to the appropriate place to take the sample. A biopsy are most often done to examine tissue for disease. A biopsy may also be done to match organ tissue before a transplant. http://www.nlm.nih.gov/medlineplus/ency/article/003416.htm http://en.wikipedia.org/wiki/Biopsy
Why does ovarian cancer show the most aggressive growth?
Not always but it is considered one of the most aggresive. If a biopsy is done on it the cancer can spread by following the tract of the needle used to biopsy it. Biopsies used to be done on ovarian but they learned the hard way that you must surgicaly remove them instead.
Can you float a needle?
Yes, you can float a needle I have done it before. It doesn't have to do with density though it has to do with surface tension.
What prostate cancer tests are currently available and what is their accuracy?
Digital Rectal exam; blood test for PSA level; transrectal biopsy. Only the biopsy can tell for sure if cancer is present. And it is not 100% accurate as the biopsy needle may miss the cancer on the first sampling. The test may need to be done again a few months down the road.
Lung needle biopsy?
DefinitionA lung needle biopsy is a method to remove a piece of lung tissue for examination.Alternative NamesTransthoracic needle aspiration; Percutaneous needle aspirationHow the test is performedA chest x-ray or chest CT scan may be used to find the exact spot for the biopsy. If the biopsy is done using a CT scan, you may be lying down during the exam.A needle biopsy of the lung may also be performed during bronchoscopy or mediastinoscopy.You sit with your arms resting forward on a table. You should try to keep still and not cough during the biopsy. The doctor will ask you to hold your breath. The skin is scrubbed and a local pain-killing medicine (anesthetic) is injected.The physician will make a small (about 1/8-inch) cut in the skin, and will insert the biopsy needle into the abnormal tissue, tumor, or lung tissue. A small piece of tissue is removed with the needle and sent to a laboratory for examination.When the biopsy is done, pressure is placed over the site. Once bleeding has stopped, a bandage is applied.A chest x-ray is taken immediately after the biopsy.The procedure usually takes 30 - 60 minutes. Laboratory analysis usually takes a few days.How to prepare for the testYou should not eat for 6 - 12 hours before the test. Your health care provider may tell you to avoid aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, or blood thinners such as warfarin for a period of time before the procedure. Always check with your health care provider before changing or stopping any medications.Before a needle biopsy of the lung, a chest x-ray or chest CT scan may be performed. Sometimes, you will be given a mild sedative before the biopsy to relax you. You must sign a consent form. It is important to remain as still as possible for the biopsy and avoid coughing.How the test will feelYou will receive an injection of anesthetic before the biopsy. This injection will sting for a moment. You will feel pressure and a brief, sharp pain when the needle touches the lung.Why the test is performedA needle lung biopsy is performed when there is an abnormal condition near the surface of the lung, in the lung itself, or on the chest wall.The test is usually done to diagnose large abnormalities seen on chest x-ray or CT scan. Most often, the abnormality cannot be seen by other diagnostic techniques, such as bronchoscopy.Normal ValuesIn a normal test, the tissues are normal and there is no growth of bacteria, viruses, or fungi if a culture is performed.What abnormal results meanBacterial, viral, or fungal lung infectionCancerous cells (lung cancer, mesothelioma)Immune disorderPneumoniaThe test may also be performed for:Metastatic cancer to the lungPneumonia with lung abscessWhat the risks areIn a very small percentage of needle biopsies, a collapsed lung or pneumothorax occurs. Usually, chest x-rays will be done. However, if the pneumothorax is large, a chest tube may need to be inserted to expand (decompress) the lung.In rare cases, pneumothorax can be life threatening if air escapes from the lung, gets trapped in the chest, and presses on (compresses) the lungs and heart.Whenever a biopsy is done, there is a risk of excess bleeding (hemorrhage). Some bleeding is common, and a health care provider will monitor the amount of bleeding. Rarely, major and life-threatening bleeding may occur.A needle biopsy should NOT be performed if other tests show that you have:Blood coagulation disorder of any typeBullae (enlarged alveoli that occur with emphysema)Cor pulmonaleCystsPulmonary hypertensionSevere hypoxiaSpecial considerationsSigns of a collapsed lung include:Blueness of the skinRapid heart rate (rapid pulse)Shortness of breathIf any of these occur, report them to your health care provider immediately.
How is a brain biopsy done?
Brain biopsies are a medical procedure used to remove a piece of tumor or tissue from the brain for testing. This can be done by drilling a small hole in the skull and inserting a hollow needle or by a surgeon removing a part of the skull and removing the tissue.
