Cancer
is really at an all time high I think. In recent times, almost one in ten
people I have come across, has got cancer, or a family member who has been
diagnosed of the deadly disease. Just a couple days ago, a client relived a
very sad incidence of how she was planning for her second child, and she just
went to her GP, to ensure all was well and to do the preliminary checks, and in
24 hours, her phone was buzzing with distress calls from the surgery, only to
be told to come back to the surgery ASAP, and trust me, when your surgery gives
you such calls, its hardly ever positive feedback and in this lady's incidence,
that was how she began her battle with cancer. Very sad indeed. I have said in
a couple posts, that all we can do is make plans, but the outcome, is entirely
out of our control. And if you are like myself, that has strong faith in the
power of God, your perception and attitude to life, is changed by the realities
of life.
However,
thank God for doctors and the researchers among them who keep on looking for
ways to make life better, and when I watched this documentary on the new
surgical knife that detects cancer, I was overly impressed and her to share the
write up written by Maria Cheng;
LONDON
(AP) — Surgeons may have a new way to smoke out cancer.
An
experimental surgical knife can help surgeons make sure they've removed all the
cancerous tissue, doctors reported Wednesday. Surgeons typically use knives
that heat tissue as they cut, producing a sharp-smelling smoke. The new knife
analyzes the smoke and can instantly signal whether the tissue is cancerous or
healthy.
Now
surgeons have to send the tissue to a lab and wait for the results.
Dr.
Zoltan Takats of Imperial College London suspected the smoke produced during
cancer surgery might contain some important cancer clues. So he designed a
‘‘smart’’ knife hooked up to a refrigerator-sized mass spectrometry device on wheels
that analyzes the smoke from cauterizing tissue.
The
smoke picked up by the smart knife is compared to a library of smoke
‘‘signatures’’ from cancerous and non-cancerous tissues. Information appears on
a monitor: green means the tissue is healthy, red means cancerous and yellow
means unidentifiable.
To
make sure they've removed the tumor, surgeons now send samples to a laboratory
while the patient remains on the operating table. It can take about 30 minutes
to get an answer in the best hospitals, but even then doctors cannot be
entirely sure, so they often remove a bit more tissue than they think is
strictly necessary.
If
some cancerous cells remain, patients may need to have another surgery or
undergo chemotherapy or radiation treatment.
‘‘(The
new knife) looks fabulous,’’ said Dr. Emma King, a head and neck cancer surgeon
at Cancer Research U.K., who was not connected to the project. The smoke
contains broken-up bits of tumor tissue and ‘‘it makes sense to look at it more
carefully,’’ she said.
The
new knife and its accompanying machines were made for about £250,000 ($380,000)
but scientists said the price tag would likely drop if the technology is
commercialized.
