Breast cancer: Less false positive results thanks to new technology
Around 70,000 women in Germany develop breast cancer every year. Breast cancer is the most common tumor in women. As a rule, the chances of a cure increase the earlier the tumor is discovered and the more precisely it can be diagnosed. A new technology is now available for this.
Most common malignant tumor in women
Breast cancer, also called breast cancer, is the most common malignant tumor in women. In Germany alone, 70,000 new cases are counted annually. A new technology now allows more precise images of the breast tissue without additional radiation exposure, reports the University Hospital Freiburg in a message. In addition, false positive results are minimized.
Although women aged 50 to 69 can take part in the breast cancer screening program free of charge, in some places only about every second person goes to mammography screening. Women are often afraid of the examination - it is not entirely painless. Even though it is known that the examination does not offer a guarantee, according to experts, more than 17,000 carcinomas could be detected by mammography screenings within one year. However, it is often criticized that the examinations also lead to many overdiagnoses.
Minimization of false positive results
Thanks to a new technology, false positive results can be minimized, reports the Freiburg University Hospital: For optimal diagnosis, conventional 2D mammography images of the breast tissue are combined with 3D images from tomosynthesis.
“Thanks to the 3D representation, it can be determined with great certainty whether densifications in the 2D image can only be attributed to an overlay in the tissue or actually to a carcinoma. In this way false positive results can be minimized, ”explained Prof. Dr. Mathias Langer, Medical Director of the Radiology Clinic.
Further development of diagnostic security
This is made possible by a new X-ray technology that is being used for the first time in Central Europe. This is in the gynecological radiology department of the Radiology Clinic at the University Hospital Freiburg. According to the information, it represents a significant development in diagnostic safety.
"Thanks to newly developed computing methods, the image quality is significantly increased, we can recognize microcalcifications more clearly and identify changes more easily than benign or malignant," said Prof. Langer.
Radiation exposure is reduced
In addition to the improved diagnostic options, the new technology also helps to reduce radiation exposure. One of the conventional 2D mammograms is no longer required and the total X-ray dose is reduced by around 20 to 30 percent.
"This enables us to use all technologies without significantly increasing radiation exposure for the patient," said Dr. Marisa Windfuhr-Blum, senior consultant in gynecological radiology at the University Hospital Freiburg.
In combination with a clinical and an ultrasound examination, the new system, according to the experts, allows a significant improvement in diagnostics. (ad)
