2. What is oral cancer?
 Oral cancer, or mouth cancer, is
a cancer that can occur in any
part of the mouth, from the lips,
cheeks, and tongue, to the
gums, salivary glands, and
tonsils. Unfortunately, there are
very few visible signs of oral
cancer in its early stages. This
means that without proper and
regular screening, oral cancer
can go undetected until it has
progressed into its late stages,
lowering the chances that it
can be treated successfully.

3. Risk factors for oral cancer
 Smoking cigarettes or chewing
smokeless tobacco
 Sun exposure to the lips
 Excessive alcohol consumption
 Oral infections such as HPV
 Previous head and neck cancers

4. Oral cancer
screening
saves lives
 Screening is what dentists do to try and identify
diseases like oral cancer before the diseases
are showing any visible signs. This means that
screening can help in detecting ad diagnosing
oral cancer in its early stages, and treatment
options can be explored as soon as possible.
The sooner that oral cancer is diagnosed, the
more likely it is that treatments will be
successful.
 Oral cancer screening by dentists is generally
done by examining the mouth and neck. This
examination can be even more
comprehensive with the help of devices that
use light to detect signs of oral cancer, such as
skin abnormalities, that may have been
overlooked by the naked eye. One of these
devices is VELscope.

5. Velscope, or the VELscope® Vx Enhanced Oral Assessment System, is a wireless
handheld device that uses natural tissue fluorescence to enhance our ability to
detect abnormalities in the mouth that are often invisible to the naked eye. It is
considered the world’s most widely-used adjunctive tool for the visualisation of
tissue abnormalities in the mouth, as it is convenient, easy-to-use, and utilises
simple and intuitive technology.

6. How Was the VELscope Developed?
With the support of more than $50 million in
research funding from institutions like the
British Columbia Cancer Agency, the
United States National Institutes of Health
and the M.D. Anderson Cancer Center at
University of Texas, the VELscope was
developed. Conceptualized by the British
Columbia Cancer Agency and LED Dental,
the product was released in 2006 as the
very first tissue fluorescent device
commercially available to dentists.
In 2008, a second-generation device was
released which featured multiple
advancements, including a more powerful
lamp. To date, The VELscope system
remains one of the most popular and
effective devices for early detection of oral
tissue abnormalities.

7. Benefits of
Velscope®
 Completely noninvasive:
no patient discomfort
 Easy photo-
documentation of
suspicious lesions in the
mouth
 Affordable to patients: a
mere handful of dollars
more per visit
 Quick and easy to
incorporate into a
regular dental checkup

8. Dentists report excellent
Velscope results:
 Reports and clinical experience prove that
Velscope technology is a helpful tool in further
examining oral health issues. Clinicians also
report relative ease when the technology is
incorporated into the dental practice as it
can easily photo-document any suspect
areas for possible surgical biopsy.
 approximately 643,000 worldwide cases
reported annually.

10. How does Velscope work?
Velscope uses a superior blue light to excite molecules deep within
the layer of our oral mucosal tissues, i.e. the mucous membrane
lining the inside of the mouth
These excited molecules then emit their own light in shades of
green, yellow, and red
The Venoscope's proprietary filter makes fluorescence visualisation
possible through blocking the reflected blue light and enhancing
the contrast between the normal and abnormal tissue.
10

11. Abnormal fluorescence patterns may arise
from a number of causes, including:
 Increased metabolic activity in the epithelial tissue
 A breakdown of the fluorescent collagen cross-links in the connective
tissue layer beneath the basement membrane
 An increase in tissue blood content from inflammation or angiogenesis
as hemoglobin strongly absorbs fluorescence excitation (blue light)
 Presence of melanin or amalgam particles which absorb light

12. Preventing Oral Cancer
with Velscope®
Although prognoses of late-stage oral cancer
are uncertain, catching oral cancer early
increases the average survival rate to between
80 and 90%. Your dental care provider plays a
chief role in helping you prevent oral cancer;
the screening process is made easier with
products like Velscope® that can pick of signs
of cancer invisible to the naked eye.
