Melanoma Network of Canada
Annette Cyr, Chair, MNC
Our Organization
• To provide melanoma patients and their caregivers
with current and accurate information and services in
the fight against melanoma;
• To increase public awareness of malignant melanoma
and skin cancer through Education and Advocacy
across Canada;
• To advocate for improved treatment options and
ultimately find a cure for Melanoma.
Melanoma: Fast Facts
• Melanoma is one of the fastest growing cancers worldwide.
In Canada, this form of skin cancer has more than tripled
over the last 30 years and continues to increase.(Public Health
Agency of Canada. “Melanoma Skin Cancer Facts and Figures.”
• Second most common cancer in North American women
between the ages of 20 and 40 and leading cause of cancer
death in women ages 25 to 30 and is second only to breast
cancer in women aged 30 to 34 (Source: SEER-Surveillance, Epidemiology and
End Results data, http://seer.cancer.gov)
• Approximately 5800 invasive melanomas diagnosed in
Canada in 2012, and approximately 980 deaths; over
80,000 cases of other skin cancers
• Overexposure to ultraviolet (UV) radiation either from the
sun or from artificial sources such as tanning beds is the
leading factor in the development of skin cancers and is the
most preventable cause of the diseases. (Canadian Dermatology
Association. 2010 Melanoma Fact Sheet.)

How Tanning Causes Cancer
Tanning is the body's response to UV damage. All tans are skin
damage.
Exposure to the mid-day sun can produce as many as 40,000
DNA errors an hour (Regina Santella, a professor of environmental health sciences at Columbia
University's Mailman School of Public Health in New York)
The UV light causes the DNA molecule thymine to bind to
adjacent thymine molecules that renders both molecules
unreadable during transcriptions - errors occur in areas of DNA
that regulate cell growth and skin cancers like melanoma can
begin to develop.
Most times, skin cells rapidly repair most of those 40,000 errors,
but over time repeated errors can cause cancer or other problems.

It Isn’t Pretty
That Suntan Can Kill
• People who have tanned indoors have about a 75 percent
higher risk of melanoma, on average, than people who have
never tried it.
• Compared with people who had never tanned indoors, those
who tanned in high-speed and high-pressure machines had
roughly three and 4.5 times the risk of developing
melanoma, respectively.
• High-speed machines use higher amounts of ultraviolet-B
(UVB) light while high-pressure machines use more
ultraviolet-A (UVA). (Journal of Cancer Epidemiology, Biomarkers and Prevention, May 2010)

The ABCDEs of Melanoma
Asymmetry – one half is unlike the other
Border – An irregular, scalloped or poorly defined
border
Color- Is varied from one area to another; multiple
shades of tan, black brown, red, white or blue
Diameter – If greater than 6 mm (pencil eraser tip);
but can also be less
Most important - Evolving – a mole that is changing,
oozing, itching or bleeding or looks different from the
rest (the ugly duckling)
