乳房射影 Mammography 的安全性 可以常作嗎?

今天在中廣的美的世界專訪一位一般外科的醫生

他說:

"國人乳癌的年齡約為47歲

較歐美的50多歲年輕

但國人發現就醫多是已經是摸的到腫瘤的二期

而健保是只有給付50歲以上的人作乳房射影

原位癌就發現有乳癌

最好從35歲開始作檢查

一年作超音波 一年乳房射影

我的問題是國內這種乳房射影檢查的劑量

是不是和國外的一樣

是不是國內一般大醫院用的儀器和國外先進國家一樣新

我想問的是過去會有疑慮

這種檢查接受的輻射線到底高不高

安不安全

如果常作的話

有在網路上看到這一篇說

"If a woman had annual screening mammography for fifty years (two x-ray views per breast), beginning at age 40 years and continuing until age 90, she will have received a total of 10 rads to 20 rads per breast over the course of 50 years."

Benefits and Risks of Mammography

不知道是真是假??

因為儀器廠商西門子Siemens贊助的網站

希望有放射腫瘤科

專門在算癌症病人接受用劑量的放射師

或是一般外科的乳房專科醫師

或是專門在做乳房射影的放射師大大們

可以替我解答

謝謝

    Mammography

    From Wikipedia, the free encyclopedia

    Mammography.Mammography is the process of using low-dose X-rays (usually around 0.7 mSv) to examine the human breast. It is used to look for different types of tumors and cysts. Mammography has been proven to reduce mortality from breast cancer.

    Risks

    False positives

    False negatives

    Other risks

    The majority of health experts agree that the risk of breast cancer for asymptomatic women under 35 is not high enough to warrant the risk of radiation exposure. For this reason, and because the radiation sensitivity of the breast in women under 35 is possibly greater than in older women, most radiologists will not perform screening mammography in women under 40. However, if there is a significant risk of cancer in a particular patient (BRCA positive, very positive family history, palpable mass), mammography may still be important. Often, the radiologist will try to avoid mammography, by using ultrasound, or MRI imaging.

    Regulation

    Mammography facilities in the United States and its territories (including military bases) are subject to the Mammography Quality Standards Act (MQSA).

    疑慮:

    乳房攝影所用的X光劑量約為0.7毫西弗,相當於一般人三個月內所承受的背景輻射量(來自環境,日常生活中處處都有背景輻射),對人體損害極微。為保障民眾安全,美國聯邦政府公佈的乳房攝影方針要求每部攝影機每年都要經技師檢查,確定其輻射量在安全範圍內。

    懷孕婦女最好避免做乳房攝影。若是有可能懷孕,一定要告訴醫師或放射技師
