What is a gentle aspiration of the needle?
Fine needle aspiration is a clinical procedure performed to seek signs of cancer, infection and other types of diseases in suspicious mass of body tissue. A long thin needle is inserted into a suspicious tumor and a small sample of liquid and tissue is extracted. Laboratory tissue analysis can help doctors confirm or exclude various health conditions. In most cases, the aspiration of fine needles can be performed within minutes at an outpatient surgical clinic or hospital. The most common places for aspiration tests are tangible lumps in the lymph nodes of the neck, head, breast and groin, but the doctor may decide to proceed to the weight elsewhere on the body if it is close to the skin and suspect. Needle biopsy is almost always preferred to more invasive surgical procedures The risk of infection and other complications is much lower.
before the procedure specialist thoroughly sterilizes the skin aboveweight and indicates the injection point. Most of the fine aspirations of the needle are performed without anesthesia, but the doctor may decide to use a local anesthetic if the skin is tender or the patient is nervous from the needle. The hollow needle punctures the skin and enters the center of the lump. A small cell sample is drawn by a needle into a sterile syringe. The doctor then carefully removes the needle, exerts pressure on the blow to pierce to control any bleeding, and bandages of the wound with gauze and glue.
The sample taken by aspiration of fine needles is transferred to a sterile laboratory image so that it can be analyzed under the microscope. The pathologist studies a sample to check symptoms of cancer, inflammation and infection. After the diameter is confirmed, a team of doctors can begin to consider different treatment options.
In addition to being an important diagnostic procedure, the aspiration of fine needles may also be useful when measuring the success of treatment procedures. The doctor may perform aspiration after attempting to treat tumor by radiation and chemotherapy and compare the collected tissue with gatheringa honest sample before treatment. If the new sample is without cancer or shows signs of cancer, it may be sure that the treatment was effective.
