Karl Loren Note: Despite the deceptive name, this is not a
"knife" or "surgery" treatment, but a radiation treatment claimed to be so
precise as to not damage so many adjoining tissues as are normally included in
traditional cancer radiation.
Bonnie's radiation treatment was deliberately aimed at 5 cm
above, 5 cm below, etc., where the main mass of the cancer was shown to be by
CAT Scan. Since the PET Scan (more discriminating than the CAT scan) can
only see cancer cells of 7 mm or larger, it would be easy for live cancer cells,
smaller than 7 mm, to be some small distance from the main cancer mass, and be
missed unless this method of deliberately targeting some amount over and under
the known mass.
Radiation is a "beam of free electrons" and I know of no method
by which the "reach" of this beam can be held to just the "thickness" of a
cancer. In other words, the beam might be tightly controlled to the edges
of the cancer, but would shoot through the cancer, and whatever was in front, or
behind, to kill whatever good cells might be there.
I may be wrong on this, but these comments are what any informed
technician would ask about -- and for which I did not find answer s on their web
site.
I've checked this out, a bit, and all the
information on the web is to offer a "business plan" where you can invest your
money to set up a "referral center." The technology is amazing,
as implied,
and suggests "surgery" without blood and without any incision into the body.
In fact this nothing more than more carefully aimed radiation, not surgery.
To say that "there is no blood" is to imply that it is, somehow, bloodless
surgery.
Presumably after you invest in the training to "run" a referral center, your
"business opportunity" would be to refer patients to the ONE (??) facility
where this machine is working? I did not check that far -- all you can get
on the web is information on HOW to request brochures and paper that describe
how you can invest in a business plan to refer -- not to own or operate a
device. It sounds like a high technology device that may or may be real,
but will certainly cost a great deal of money to get started.

Introduction
The CyberKnife® represents an
entirely new approach to radiosurgery.
Incorporating a compact, lightweight linear
accelerator mounted on a robotic arm, the CyberKnife provides the surgeon
unparalleled flexibility in targeting.
Advanced image guidance technology tracks
patient and target position during treatment, ensuring accuracy without the use
of an invasive head frame.
The CyberKnife with DTS (Dynamic Tracking
Software) is cleared to provide radiosurgery for lesions anywhere in the body
when radiation treatment is indicated.
The CyberKnife has often been used to
radiosurgically treat otherwise untreatable tumors and malformations. Moreover,
this instrument treats tumors at body sites, most of which are unreachable by
other stereotactic systems.

Subject: About Bonnie...resources for you two...keep hope alive....
Thanks for letting us share in Bonnie's treatments and recovery...I just got to
read your newsletter after being away for a while...
I don't know if this helps: but I had a tumor in an "odd"
place and after doing internet research I found help at Stanford Hospital in
Palo Alto...my own hmo doctor didn't wish to share with me this resource.
For about two years I lived with a brain tumor(turned out to be benign
..knocking on wood) on a watch and wait status and did my own research and found
this resource:
http://www.accuray.com/cyberknife.htm
read about this...Perhaps it can help as you put the puzzle pieces together.
You see, I found once you're diagnosed and get the cancer size and staging, you
don't always have to go the chemotherapy route: one alternative is to seek the
latest computer technology in the bio field...dr's don't tell you about the
clinical trials in this area. Now this machine which was used on my tumor was
able to abate it's growth after 3 daily treatments (outpatient) without screws
to the head or anything. The latest technology was to take a picture of the
tumor site and the computer directs the arm of the robot to treat it. It has a
high accuracy rate...
Another thing I learned is to ALWAYS seek a 2nd and 3rd opinion from a dr at a
research hospital such as Stanford...
Anyway I highly recommend them....
And as far as alternative approaches outside of medicine , don't give up on the
field of Macrobiotics...here is a link:
http://www.kushiinstitute.org/whatismacro.html
Keep an open mind: trust your instincts; get second opinions, and don't be
afraid to try some alternatives...
Keep the faith,
Sandra

overview
The CyberKnife® Stereotactic Radiosurgery System is the only
radiosurgery system with
|
• |
a compact 6-MV linear accelerator, |
|
• |
a computer-controlled robotic arm with
six degrees of freedom,
and |
|
• |
image-guidance
technology that eliminates the need for a rigid stereotactic frame
and enables treatment of extra-cranial sites. |
This combination of technology provides an
essential advantage: unmatched maneuverability in targeting.
Compared to conventional stereotactic
radiosurgery systems, the CyberKnife system provides:
|
• |
increased access to and coverage of
any target volume |
|
• |
broader range of
clinical applications
including |
|
|
- |
ability to treat lesions in and around
the cranium that are unreachable with other systems, for example, in the
low posterior fossa and foramen magnum |
|
|
- |
enhanced ability to avoid critical
structures |
|
|
- |
capability to treat lesions in the
neck and spine |
|
|
- |
ability to treat larger tumors |
|
|
- |
ability to treat tumors that are
inoperable |
|
|
- |
ability to treat lesions throughout
the body |
|
• |
delivery of highly conformal
dose distributions |
|
• |
option of
fractionating
treatment |
|
• |
potential to target multiple tumors at
different locations during a single treatment |

Dear Accuray,
I've been reading your web and wonder
about something.
I understand that the beam of
radiation can be tightly controlled to a known mass, but it seems that the
beam still has to "enter" the body, and "leave" the body. No matter how
tightly controlled the target is as to "sides" the "in front of" and "behind"
areas would seem to be affected the radiation beam -- causing the normal
damage caused by radiation.
Am I missing something?
