• Easy to avoid
• Use sunscreen
• Reduce sun exposure between 11am and 4pm
• Watch for changes in moles or freckles
• Easy to avoid cancer by using sunscreen especially important for light skin people
• UV- A rays are not as powerful as UV-B rays but they are responsible for penetrating through the skin,
wrinkling of skin, prematur aging, skin cancer
• UV-B rays are shorter but stronger and are thought to be primary responsible for sun damage, cancer
• Both rays are obtained from the sun, however UV-B rays are stronger in the summer

• It starts as a brown spot like a freckle, asymmetrical, maybe 2 or more colors
• People with white, light skin are more likely to develop melanoma rather than other people

• It is estimated of 60-70% of the incidents of cancer in Canada could be prevented if Canadian changed to
healthier lifestyles (e.g using sunscreen)`
