A newly developed technology allows the safe application of radiotherapy in prostate cancer. The technology allows controlled, moderate doses of radiation to be sent to the prostate without the risk of affecting collateral tissues such as the bladder, urethra and rectum. The research paper is presented in Cancer. Prostate cancer is the most common form of cancer in men. It occurs when abnormal cells form in the prostate gland and they begin to grow into neoplasms. This growth in some cases is slow and for years the tumor grows without showing itself. This makes prostate cancer difficult to detect in its early stages, although in modern medicine there are open indicators for its early registration. Only at an advanced stage does prostate cancer begin to manifest itself with noticeable symptoms – these are most often various problems with urination or ejaculation, but in some cases the disease can manifest itself in another way – metastasis of the tumor to other places can cause pain in the legs. Sometimes the disease can be the cause of prolonged weight loss. The treatment of prostate cancer usually depends on the specifics of the disease in the particular patient, as well as the stage of development of the tumor in the body. Some possible treatments are hormone therapy, chemotherapy, and radiation therapy. Another possible way to remove the tumor is surgical removal, which is often combined with radio or chemotherapy to remove the remnants of the cancer. Radiotherapy is the treatment of cancer using radiation. It directly attacks cancer cells, damaging their DNA. This results in their inability to divide. One of the risks that radiotherapy entails is damage to other cells in the body that are immediately around the tumor. But this problem is potentially solved by scientists because of their innovative technology for applying radiotherapy. It allows precise, moderate and controlled doses of radiation to affect only the cancer cells in the prostate gland. The technology also allows for real-time cancer monitoring, as well as the ability to adapt to different types of cancer and potential changes in anatomy. The technology is called MRg-A-SBRT and data from the scientific paper indicate a significant decrease in the side effects of the treatment compared to conventional radiotherapy. References: Wiley.
