To develop a new method for the early diagnosis of prostate cancer Scientists at the Weizmann Institute in Israel have developed a new method for the early diagnosis of prostate cancer. They have mapped and mapped the zinc concentration in the prostate to discover and predict cancer, which has opened up an early diagnosis of prostate cancer. New road. Studies have shown that the abundant natural zinc in the prostate plays an important role in protecting the health of the prostate. Once the prostate tissue becomes cancerous, the zinc concentration will be significantly reduced. Based on this feature, the researchers used X-rays to analyze the zinc concentration in 600 patients' sliced ​​tissue and compared it with their blood zinc concentration. The results show that at the early stage of the onset, the decrease in the concentration of zinc in prostate cancerous tissue can be detected; the researchers also found for the first time that the degree of this zinc concentration reduction is closely related to the invasiveness of cancerous tissue-the more invasive , The lower the zinc concentration. The zinc concentration in the surrounding benign tissues remained normal. This finding indicates that by mapping the prostate zinc concentration, it may be used as a method for early diagnosis of cancerous tissue. In the subsequent experiments, the researchers studied their feasibility. Through computer simulation imaging, they analyzed the relationship between zinc concentration changes and prostate cancer. It was found that this method can not only determine the degree of malignancy, but also show whether the cancer will spread to areas outside the prostate. At present, scientists have launched a special R & D program to accelerate the development of this non-invasive cancer detection method. They believe that although this study is still several years away from clinical application, once it is put into use, it will greatly improve the accuracy of early detection of cancer.
