The initiation of uncontrolled growth of cells in the prostate gland results in prostate cancer. The prostate gland is a gland in males responsible for making some fluid that later becomes a part of the semen. Situated in front of the rectum and below the bladder, the prostate gland has seminal vesicles behind it that make the majority of the semen fluid. The urethra is a tube responsible for carrying semen and urine out of the body as it passes from the prostate gland. Prostate cancer is mostly an adenocarcinoma that develops from the prostate gland cells.
Working of the Cyberknife System for Prostate Cancer treatment
The Cyberknife Radiosurgery begins with tracking of the tumor position with the help of fiducial markers. Usually, there are 4 to 5 treatment sessions for a period of 1 week to 2 weeks. The total dose of radiation provided is around 30 Gray and each treatment session lasts for 1 hour or a little more. The robotic arm of Cyberknife moves around you to deliver precise radiations on the tumor while sparing the normal tissue. With fewer side effects, the procedure is performed on an outpatient basis while ensuring the accuracy of the treatment.
The success of the Cyberknife Radiosurgery for Prostate Cancer
In most cases, doctors prefer Cyberknife Radiosurgery for treating Prostate Cancer in the initial stages where it affects only the gland and not other areas. The treatment procedure can be used alone or in conjunction with other treatments if the cancer reach is beyond the prostate gland. Most patients with prostate cancer who got treated through Cyberknife Radiosurgery experienced recurrence-free success in the treatment. Cyberknife Radiosurgery also helped in lowering the Prostate-specific antigen levels
that indicate no signs of recurrence of the cancer tumor for the long term, when tracked regularly.
FAQs
The treatment procedure has a robotic arm moving in varying directions to target the prostate. The arm delivers radiations that are confined to the region of the prostate and avoid exposure to the healthy tissues.
Cyberknife Radiosurgery is a good treatment procedure for prostate cancer if you have a tumor in the early stage or if the cancer tumor is localized. Also, if you have a tumor untreatable by other options like surgery or have a compromised health condition, Cyberknife Radiosurgery is a desirable choice for you.
Radiation therapy is amongst the common treatment choices for prostate cancer that treats the cancer cells with high-energy particles. However, traditional radiation therapy has numerous side effects.
Cyberknife Radiosurgery offers more accuracy than radiation therapy as Cyberknife targets the cancerous tumor with no irradiation of normal tissues.
There is no specific number for the size of the prostate tumor to undergo Cyberknife Radiosurgery. However, tumors in the range of around 2 cm to 8 cms can be treated with Cyberknife Radiosurgery.
