What is a gentle needle biopsy?
Fine needle biopsy is a diagnostic medical procedure performed to collect cell or fluid sample for testing. It is a common non -surgical diagnostic test performed for diagnosis and evaluation of cancer and other types of diseases. A fine needle biopsy can also be referred to as a gentle aspiration of the needle, the aspiration of fluids and the needle core biopsy, depending on the type of tissue sample obtained. The diagnosis of the disease
is the best known reason for undergoing needle biopsy. For example, this procedure is performed when someone has an unidentified lump or a weight that could be malignant. The sample taken with a needle biopsy can be tested in the laboratory for the presence of cancer cells, proteins produced by cancer cells and many other disease indicators. In the case of a person who has cancer, for examps, biopsy can be taken after surgery or other cancer treatment. In conjunction with other test results, biopsy results are used as a means to determine whether the summer wasCBA successful.
Fine needle biopsy is used to diagnose and evaluate what is called surface lumps or masses. This means that lump or matter is located just below the skin, rather than in one of the cavities of the body. In contrast, excision or open biopsy is a surgery in which the cut is carried out under a general anesthetic, which allows the surgeon to access tissues in the body cavity.
In order to prepare for a biopsy, the patient must stop using all blood weight loss medications for one week before the procedure. This includes prescription medicines as well as over -the -counter medicines with properties with developing blood. In addition, patients must not eat several hours before the biopsy.
Before starting biopsy, vital symptoms of the patient, including temperature, blood pressure and pulse, are taken. If the patient is very anxious and unable to relax, he could have an oral sedative as a help to relax. After completeThe preparation is sterilized and then anesthetized by a local anesthetist. If necessary, the location of the mass could be determined by the X -ray before the biopsy itself.
After determining the location, a very fine needle is inserted into the mass to withdraw the cells of cells and liquid. Often several samples are taken from different places inside the mass. This is important because if only one sample is removed, the accuracy of the test will decrease, may lead to a false negative result or indeterminate diagnosis.
Small side effects of fine needle biopsy, such as bruising and tenderness at the place of needle, are quite common. Depending on the biopsy, small amount blood in mucus or urine is also normal. If symptoms such as chills, fever, severe biopsy pain, breathing problems, dizziness or chest pain should be immediately sought.
