乳がんを高い精度で発見できる新たな画像検査法が開発されました。
Researchers develop ‘pain-free’ breast cancer detection
A group led by Kobe University has developed a new image inspection method to detect breast cancer with high accuracy by using a transmitter that sends weak radio signals that is used over the breast.
The method provides clear three-dimensional images without inflicting pain on patients, unlike mammograms that are currently used for breast cancer screenings, according to the group. The group aims to start clinical trials in fiscal 2019 in a bid to spread the new technique in screenings.
Kobe University Prof. Kenjiro Kimura, a specialist in metrology, and other researchers looked at the fact that breasts are mostly made of fat, with radio waves deflecting body tissue but penetrating fat.
The group established the method of instantly creating a stereoscopic image of cancerous tumors by transmitting radio waves to a breast and analyzing the waves that were deflected off tumors.
中略
The group looked into the accuracy of the new method by testing about 200 people, including cancer patients with dense breast tissue. The results matched with over 90 percent of the results of other types of examinations such as mammograms, ultrasonographic scans and biopsies. The group was also able to detect early-stage cancer, which is difficult to detect using standard methods.

biopsy /bάɪɑpsi/ を取り上げます。マンモグラフィー検査などと並んで述べられていることから、検査の1つであると予想しました。『ライトハウス英和辞典』（第5版 研究社）で調べると「生体組織検査、生検」とありました。
LDOCEには “the removal of cells, tissue etc from someone’s body in order to find out more about a disease they may have” と定義されています。
この新しい検査方法では、電波ががん組織に当たって跳ね返った波形を解析し、立体画像化できるそうです。（aqua）
