3D breast tomography improves detection rate of breast cancer

        According to the Ministry of health and welfare, breast cancer is the highest incidence of cancer among women in Taiwan. Early detection will reduce the risk. This paper introduces the latest breast tomography technology, which can not only reduce the discomfort, but also effectively find the symptoms and early treatment.

        Because of the changes in lifestyle, eating habits and environment, the incidence rate of breast cancer among many modern women is increasing year by year, while the age of breast cancer is decreasing. The peak population is concentrated in the age range of 40-50 years old, which is 10 years younger than that of European and American women, and the period of diagnosis is later than that of European and American women.

                A 68 year old woman in New Taipei city had no breast symptoms and discomfort. When she received the screening of bureau of health promotion 2D mammography every two years, doctors found that her breast was dense and unevenly distributed, and it was difficult to clearly distinguish the results from the images. After suggestions, she further accepted 3D mammography, A small irregular tumor of 0.4cm in shape was clearly detected in the upper inner region of the right breast. It was confirmed as early invasive breast cancer by ultrasound and biopsy.

        The breast tissue of Asian women is denser than that of traditional mammography

        "Mammography screening" is the most effective examination to reduce the mortality of breast cancer in women confirmed by clinical studies, which can reduce the mortality by 20% - 30%. However, the traditional mammography is a 2D image, all breast tissues and lesions are overlapped, which is not easy to distinguish, especially in Asian women, most of the breasts belong to the type of dense breast tissue, Tumors are more likely to be covered by the breast and cannot be seen. The proportion of "false positive" and "false negative" detected by screening is high (about 10% - 20% of women's breast cancer in Taiwan can't be detected by traditional 2D mammography). As a result, although patients maintain regular examination, they still can't find cancer early. In addition, 2D breast imaging is also prone to be mistaken for tumor focus due to uneven overlapping of breast and fibrous tissue, and unnecessary re examination or biopsy is performed.

                The detection rate of invasive breast cancer increased by 41% after multi angle photographing

        Fortunately, the 3D breast tomography technology developed in recent years can make up for the limitation of 2D photography. The images are taken from multiple angles, and then recombined by computer to present dozens of 1 mm thick thin section images. Compared with traditional 2D mammography, which only has two fixed angles, 3D breast tomography can eliminate overlapping tissue interference, It can help to distinguish the real lesions from the overlapping non-uniform breast tissue, greatly reduce the false negative and false positive interpretation, reduce the waste of medical resources, and improve the detection rate of breast cancer.

        According to foreign medical research, compared with 2D mammography, 3D mammography can improve the detection rate of breast cancer by 29%; Among them, the detection rate of invasive breast cancer can be increased by 41%. In addition, the arc-shaped compression plate equipped with 3D mammography can effectively reduce 40% of the breast pain caused by compression during detection, so that women will no longer reject screening due to discomfort during examination. Women friends, love others, love yourself more! Take care of your family and work, and don't forget to receive mammography regularly.
