What is the difference between radiation and CyberKnife for prostate cancer?
Cyberknife Is More Accurate Than Traditional Radiation Therapy. Because it's able to target diseased tissue, Cyberknife SBRT is much more accurate than traditional radiation therapy. SBRT can deliver radiation to a margin of one to five millimeters surrounding a tumor.
Who is a candidate for CyberKnife?
Who is a Candidate for Treatment? Cyberknife is typically used for patients with: Early-stage disease. Localized disease (confined to the prostate).
Is CyberKnife better than surgery?
In many clinical situations, CyberKnife has local control and effectiveness that is equivalent to surgery. However, due to its non-invasive nature, the risk of side effects is significantly lower with CyberKnife. 2. Real-time tumor tracking results in less radiation to the nearby normal tissues.
Is CyberKnife treatment painful?
There are many benefits to a CyberKnife procedure. It is non-invasive, does not require a headframe or painful Immobilization device and it is able to reach areas of the body previously thought untreatable.
How long does it take to recover from CyberKnife?
A faster return to everyday life With CyberKnife treatment, the majority of men can continue normal activity during and immediately following treatment — compared to the typical requirement to limit normal activity for three to five weeks with traditional prostate cancer surgery.

After treatment and follow-up There are minimal side effects from CyberKnife treatment. The most common side effect is fatigue. Most of the time, patients are able to go back to their usual activities but will need someone to drive them home immediately after treatment.
Can prostate cancer come back after CyberKnife?
The two major types of prostate cancer recurrence that can be treated using CyberKnife are local and distant. Prostate cancer recurrences in the tissue surrounding the prostate, such as in the seminal vesicles, pelvic floor muscles or rectum, are known as local recurrences.
Does CyberKnife work prostate cancer?
The CyberKnife System is a non-invasive, non-surgical, pain-free treatment option for prostate cancer with proven results. It is the first and only radiotherapy device that brings true robotic precision and the ability to track, detect and correct for tumor motion in real-time, to the treatment of cancer.
What is a cyberknife?
What is CyberKnife? CyberKnife is a brand name for a device that delivers stereotactic body radiation therapy (SBRT). It’s a form of external beam radiation. It can be used to treat prostate cancer and other types of cancer. Although it contains the word “knife” and is sometimes referred to as “radiosurgery,” there’s no knife or incision.
What is Cyberknife ultrasound?
This will be similar to when you had your biopsy. CyberKnife will use the markers to track the tumor during treatment. Then you’ll need some imaging tests to assess the location, size, and shape of the tumor.
How long does it take to recover from prostate surgery?
There’s no extended recovery period. Another type of radiation used for prostate surgery is brachytherapy. It involves implanting radioactive pellets in your prostate. The pellets release radiation over a period of days or weeks. It’s a good option for early-stage or low-grade prostate cancer.
How long does radiation therapy last?
This is a noninvasive, painless procedure. Each session will last anywhere from 30 to 90 minutes. Once it’s over, you should be able to get up and resume your normal activities right away.
What to do after radiation treatment?
A few months after treatment, you’ll probably need to schedule new imaging tests, such as CT, MRI, or PET. The images will help your doctor evaluate your response to radiation treatment. If no cancer can be found, you may not need further treatment. You’ll need careful monitoring for some time, though.
Is Cyberknife good for prostate cancer?
It’s a good option for early-stage or low-grade prostate cancer. CyberKnife may be a better choice if you can’ t have anesthesia or if your anatomy makes brachytherapy difficult. If you have treatment with CyberKnife, you may need other therapies as well.
What to do if you have cancer after SBRT?
If there’s still evidence of cancer after SBRT, your doctor will make some recommendations on the next steps.
What is Cyberknife?
Cyberknife is a treatment using external beam radiation. It is the brand name of a machine that delivers stereotactic radiation therapy or "radiosurgery." Despite the name, Cyberknife does not involve a knife, cutting, or surgery for treatment.
What is Involved in Cyberknife Treatment?
You will see a urologist a week or two before treatment. This doctor will place gold markers, known as "fiducials", in your prostate as a way of marking the target. This is done under ultrasound guidance, similar to the procedure for prostate biopsy. The tumor position will be tracked during the Cyberknife treatment using the fiducials.
What are the Possible Side Effects of Cyberknife?
Side effects are similar to those with conventional fractionated radiation therapy. The side effects include:
What can you expect in Cyberknife Treatment?
CyberKnife uses a technique called stereotactic body radiation therapy. In addition, it delivers exact doses of radiation with severe accuracy. Furthermore, it makes up target motion in real-time.
Benefits of Cyberknife Treatment
The fewer clinic sees– The patient will need only four to five sessions in a week. Thus, the out-patient only have to visit the hospital when it’s necessary. Hence, fewer visits to the hospital.
Cyberknife Treatment Procedure
Prostate cancer is a severe condition that may start affecting the other organs. Therefore, cyberknife treatment is helpful to treat prostate cancer. The following is the treatment procedure:
What can you expect in Post-treatment?
Most patients experience marginal adverse effects and can swiftly return to their day-to-day routines with little interruption to their everyday tasks throughout or following their therapy.
What is a CyberKnife?
The first thing prostate cancer patients should know about ground-breaking CyberKnife Radiotherapy Treatment, is that it doesn’t involve a knife or any surgical procedure.
The procedure
The five procedures which suitable prostate cancer patients will receive, typically take less than sixty minutes each. Some patients choose to spread these five treatments throughout a fortnight, while others prefer to complete treatment within a week. CyberKnife results have proven to be equally as effective as regular radiotherapy.
CyberKnife Radiotherapy Side-effects
Although patients can resume everyday activities immediately following treatment, side-effects could be experienced.
