乳腺癌的活检诊断:磁珠和针(线)定位
如果乳房x光检查或乳房超声检查发现了无法察觉的异常, 你的十大赌博平台排行榜可能会建议使用磁性种子或针(线)定位来指导可疑组织的活检. In these procedures, 在相关区域放置一个标记,以帮助外科十大赌博平台排行榜定位并移除它. 两者都是两步门诊程序(意味着你不会在十大赌博平台排行榜过夜).
Preparing for your procedure
如果你在过去五年内在其他机构做过乳房x光检查, you must bring the images to your appointment. 为了得到它们, 打电话给进行测试的机构,要求提供胶片图像的打印输出(不是CD)。. 您的UCSF放射科十大赌博平台排行榜会将旧图像与我们在手术过程中拍摄的图像进行比较,以帮助您进行解释.
If you take medications or supplements, 在手术前询问十大赌博平台排行榜是否应该停止服用. 这包括非处方药,如阿司匹林和用于健康目的的草药.
On the day of your appointment, please follow these guidelines:
- 不要在腋下或乳房上涂抹任何粉末、除臭剂、乳液或香水. 这些产品中的物质可能出现在图像中,使它们更难解释.
- Wear two-piece clothing (separate top and bottom), so you only have to remove your top and bra f或者是 examination.
- Don't wear jewelry unless it can be quickly and easily removed.
- 提前20分钟到达,以便有时间登记和更改.
- Tell your doctor if you may be pregnant.
当你到达时,你可能会被要求填写一份简短的乳房健康问卷.
Magnetic seed localization (Magseed)
磁珠是一颗米粒大小的磁性不锈钢珠. 它被用来标记可疑乳腺组织的位置,可以在活检前30天放置. 在加州大学旧金山分校健康中心,Magseeds由专门从事乳房成像的放射科十大赌博平台排行榜放置.
Step 1: Find the abnormal tissue
This step takes place in our radiology department, 放射科十大赌博平台排行榜使用乳房x光摄影或超声波来指导Magseed的放置. 如果正在使用超声波,你将仰卧,一只手臂在头顶上. 技师会在腋下放一些垫子,让你保持舒适. If mammography is used, you'll be seated or standing.
Once the suspicious tissue is pinpointed with imaging, the radiologist cleans your breast and injects numbing medication. The injection may sting for about 15 to 30 seconds.
The radiologist then uses a thin, hollow needle to insert a Magseed into the suspicious tissue, guided by additional images. The insertion site is covered with an adhesive bandage.
Most women feel pressure or pulling but not pain. 如果您有任何相关症状,请告诉您的放射科十大赌博平台排行榜或成像技术人员.
Once the Magseed is placed, 我们做一个温和的乳房x光检查(只有轻微的压迫)来确认它在正确的位置.
Step 2: Biopsy the abnormal tissue
This step takes place in an operating room. Once you're under anesthesia, 外科十大赌博平台排行榜使用手持式磁探头定位磁籽并将其取出, along with the suspicious tissue. 标本被送到放射科,以确认目标组织被切除, then to a pathologist to determine whether it's cancer.
Needle (wire) localization
针定位(也称为线定位)是另一种标记可疑乳腺组织进行活检的方法. At 加州大学旧金山分校健康, it's used less frequently than Magseeds.
Both steps of this procedure are performed on the same day.
Step 1: Find the abnormal tissue
This step is performed in our radiology department, 放射科十大赌博平台排行榜在哪里使用乳房x光摄影或超声成像来确定异常组织并指导导线的放置. 如果使用超声波,你需要仰卧,一只手臂举过头顶. 技师会在腋下放一些垫子,让你保持舒适. If mammography is used, you'll be seated or standing.
Once the suspicious tissue is pinpointed with imaging, the radiologist cleans your breast and injects numbing medication. The injection may sting for about 15 to 30 seconds.
下一个, 放射科十大赌博平台排行榜将一根空心针穿过你的皮肤到达异常组织, then threads a thin wire through the needle to the identified site. The wire has a small hook on the end to hold it in place. Imaging is performed again to ensure the wire is placed correctly, and the wire is securely taped in place. 导线一直留在你的乳房里,直到当天晚些时候进行活检.
During this process, most women feel pressure or pulling but not pain. Some feel faint or dizzy. 如果您有任何相关症状,请告诉您的放射科十大赌博平台排行榜或成像技术人员.
Step 2: Biopsy the abnormal tissue
During this step, the abnormal tissue is surgically removed. The procedure is called an excisional biopsy and takes up to an hour.
你会被轮椅从放射科送到手术室. 家人或朋友可以在放置导线前后陪伴您,但不能在活检期间陪伴您.
Once you're under anesthesia, 外科十大赌博平台排行榜将沿着导线定位可疑组织并将其移除. The tissue is then sent to the radiology department to be X-rayed, allowing the surgeon and radiologist to confirm its removal. 最后,它会被送到病理学家那里,以确定它是否是癌症.
对一些女性来说, the biopsy causes discomfort, swelling and bruising; these side effects subside in a few days. Your breast's appearance is unlikely to change significantly, though you'll have a small surgical scar. You'll also feel some lumpiness near the incision, due to scar tissue. 你的外科十大赌博平台排行榜可能会提前告诉你疤痕的位置.
Risks and recovery
Both wire and Magseed biopsy procedures are usually well tolerated. 任何不适通常都可以通过非处方止痛药来缓解, such as Tylenol (acetaminophen), 大多数患者在第二天就能恢复正常活动. 一定要按照你的护理团队的指示,在你愈合的过程中避免哪些活动, how to care f或者是 incision and which medications to take for pain.
这些手术后有轻微的感染或大出血的可能性. 请打电话给 乳房成像 或者是 Breast Care Center immediately if you experience any of the following symptoms:
- Swelling that doesn't go away
- Continued bleeding
- A fever above 101 degrees Fahrenheit (38.3 degrees Celsius)
- 对乙酰氨基酚或其他非阿司匹林止痛药无效的疼痛
