What is Cyberknife and How Does it Work? | Ask A Prostate Expert, Mark Scholz, MD

PCRI's CEO, Alex Scholz, asks medical oncologist, Mark Scholz, MD, about Cyberknife, also known by the generic name stereotactic body radiation therapy or "SBRT." Cyberknife precisely delivers a high dose of beam radiation over a short duration (1 day to 2 weeks) with a side effect profile and cure rates comparable to longer-duration forms of beam radiation like IMRT.

If you watched this you probably have been diagnosed or know someone who has been diagnosed with prostate cancer, I went through it and I am now 6 years cancer free. I am passionate about this because I find the current attitude of doctors protecting their own specialty instead of the patients best hope for a positive outcome offensive. Each treatment has it’s best application,how early or late the disease was discovered etc. There are no blanket answers. I am only writing this to hopefully warn guys about some of the things I encountered. Cyber knife is still radiation, it still passes through other tissue. And because of that you could be prone to bladder or colon cancer in a few years. There is zero radiation in HIFU or surgery, I did HIFU because I did my research and didn’t want to risk a secondary cancer. Doctors like this should be ashamed of them selves for being so misleading. Sure its very precise where it can be aimed, but its coming from the outside of the body. and its probably passing through part of the bladder on its way in or colon on its way out. By the way that also means its passing through the nerve bundle on and around the prostate as well. Don’t believe this guy, or even me. The stakes are to high, do your own research, when I was diagnosed I spoke to at least 6

[@dmcarden]

paulsdrc if you don't mind my asking, did you get you have whole gland ablation or partial? Any side effects? I'm trying to decide on treatment path but awaiting 2nd biopsy for confirmation.

[@paulsdrc]

@@dmcarden I did the whole gland, because I was that oddball with the cancer doubling in six months, even though it was not small cell carcinoma.

[@dmcarden]

@@paulsdrc wow.. but great to see you're doing well..gleason intermediate or high? Looking into hifu as well

[@paulsdrc]

@@dmcarden I was 3+3=6 at first, they didn’t bother to check after that I went straight for a TURP to get the prostate down to size and then HIFU

[@gr8ride411]

paulsdrc Recently diagnosed with majority of cancer in biopsy samples, no abnormalities on DRE, psa 8.14, 35cc prostate, I’m 69 yo. Just completed bone and ct scans and meeting with radiology oncologist tomorrow. With a referral pending with Stanford. Did you consult with other specialists before choosing HIFU? Still trying to wrap my head around this and found your comments very pertinent. Thank you for sharing your story. 👍🏽
