Cancer incidence is increasing every year. According to statistics, about 18.1 million cases of cancer were registered in the world in 2020. If oncological pathologies were detected at the first stages of its occurrence, then in 90% of cases it would be possible to successfully cure them. Medicine is advancing, and therapy is already being successfully used to eliminate complex neoplasms that were previously considered completely untreatable. For example, the innovative cyberknife and gamma knife treatments are excellent at fighting formations in cerebrum.
CyberKnife is a linear accelerator suitable for elimination of formations with different localizations. Using this device, neoplasms that interfere with breathing are removed. System detects tumor movements and aims directly at the area of pathology.
To use the Gamma Knife, you need an accurate fixation of the head. Device is implemented if a person has cerebrum cancer, and benignant solid pathologies inside skull. To fix the head, special screws are used, which increases the risk of vascular injuries, bleeding, and migraines in the period after surgery, which is one of the disadvantages of the method.
According to Elekta, its manufacturer, device’s clarity impact is 0.15 mm. Accuray cyberknife has 0.5 mm exactness. It means radio-rays delivered by both systems target formations and do not harm healthy tissues.
Therapy using these devices is defined in stereotactic radio-surgery group. Irradiation is an excellent alternate option to surgical interventions.
Although stereotaxy can eliminate whole-nature formations, it is most often chosen if the tumor originated in:
During therapy, discomfort does not occur in both cases; so if you feel discomfort, it is important to tell the doctor about it. Therapy is carried out without narcosis, but with a fear of closed space, as well as light sedatives are provided to children.
With stereotactic manipulations, neoplasms of 3-6 cm are eliminated, depending on the place where the formation is located and nearby structures.
Radio-surgery is not used in the following cases:
It is important to tell your doctor if you are taking insulin or other medications by mouth, or have a heart valve, or clips for cerebral aneurysms or claustrophobia.
Often, such operations are performed outpatiently, but relatives should be next to the patient. In some cases, short-term hospitalization is needed. Return home is allowed a day or two after therapy.
According to official data, Cyber and GammaKnife are used in more than 700 clinics in 50 world countries. Often, patients choose therapy in Turkey, where procedure price is about 9-10 thousand dollars. In German clinics, CyberKnife cost is about 15 thousand dollars, and in Israel – from 20,000.
