Biopsy for 乳腺癌 Diagnosis: Fine Needle Aspiration
Your health care providers may refer you for a fine needle aspiration biopsy (FNA) if a lump is discovered in your breast. FNA活检用于评估肿块. 在过去, this required a sometimes painful surgical procedure that involved a longer waiting period for the results. With FNA, a sample of the lump is obtained using a small, thin needle. The test often allows doctors to make a diagnosis within two to three days of the test.
活检是如何进行的?
Your doctor will ask some questions about the lump:
- 它在哪里??
- 你是如何以及何时开始意识到这一点的?
- 你注意到有什么变化吗?
接下来,十大赌博平台排行榜会摸肿块. Before the actual biopsy is performed the doctor will give you an opportunity to ask any questions or express any concerns you might have about the procedure. After all your questions and concerns have been addressed, the actual procedure will begin.
用一只手握住肿块, the doctor will precisely sample the lump with a thin needle held in a needle holder, 它提供了更好的控制. Usually, two to three samples will be required from the lump to provide an accurate diagnosis. 在手术过程中, the doctor will usually leave the examination room with one of the slides to check that there is enough tissue to prevent the need for a second office visit.
这个过程需要多长时间?
Each sample takes about 10 to 20 seconds to obtain. The whole procedure from start to finish usually takes no more than 10 to 15 minutes. 然而, please allow an hour for your visit because of registration and possible waiting time in the office.
我什么时候能拿到结果?
Generally, your results should be available from your surgeon's office in two to three working days. The results can be grouped into three categories:
- 显然是良性的,不是癌症
- 明显恶性-癌症
- Non-definitive, less clear – most often, this will be followed by a 手术活检
这个测试有多可靠?
In the hands of a skilled FNA practitioner, this test is very reliable. In the instance of a clearly benign diagnosis, it may prevent you from undergoing surgery. In the case of a clearly malignant diagnosis, it quickly establishes the need for further treatment. In the less frequent occurrence of a non-definitive diagnosis, either repetition of the FNA or a 手术活检 is usually recommended.
Our experience at UCSF Medical Center has demonstrated a 2 percent to 3 percent chance that a cancer may not be detected. This is why you will be asked to come back for a follow-up visit. We also take into account the result of any imaging studies, 比如乳房x光检查或超声波扫描, 以及你的十大赌博平台排行榜对肿块的感觉. By doing this, the chance of missing a cancer is reduced to less than 1 percent.
可能会出现什么并发症?
由有经验的十大赌博平台排行榜执行, a fine needle aspiration biopsy is virtually free of significant complications. The most common complication is a slight bruising or tenderness of the area for a few days following the procedure. Discomfort should be relieved by an over-the-counter pain reliever such as Tylenol or the application of an icepack for short periods following your return home.
