Skin Cancer   |
|
 Energy from the sun is crucial to sustaining life and ultraviolet (UV) radiation has always been a natural part of our environment. But some forms of the sun’s energy can be harmful. As the ozone layer, our planet’s sunscreen, has thinned over the past few decades, our natural protection against the harmful effects of this radiation is decreasing.
Research shows that UV exposure can lead to skin cancer as well as contribute to cataract development (a condition of the eye), skin aging, and limit the ability of our bodies to fight off disease. There are two main types of skin cancer: Melanoma and Non-Melanoma. For more information, visit our sections on:

 Risk Factors
Although some people develop skin cancer and other UV-related damage without any of these risk factors, there are some risk factors that may make an individual more susceptible to UV ray damage.
- Light coloured skin, eyes, and hair
- Skin that freckles easily
- Large number of moles
- Work, play, or exercise in the sun for long periods of time
- Blistering sunburns during childhood
- Family history of skin cancer
- Weakened immune system
- Use of tanning beds
 Sun Safety
 Reduce your risk of damage from UV radiation by taking some important steps:
Limit the time you spend in the sun. Even if you are wearing sunscreen it is important to avoid spending a long time in the sun during peak UV periods (10:00 am to 2:00 pm). Children should not stay in the sun for long periods, even when wearing sunscreen. Plan outdoor events earlier or later in the day to avoid the midday sun.
 Be aware of the UV index – There is considerable change in Environment Canada’s UV index from day to day. When the rating goes above moderate, it is often included in forecasts.
Take precautions during peak periods and on high UV days. Adults should wear wide-brimmed hats, protective clothing, and sunglasses, and apply (and re-apply) sunscreen with a minimum of SPF 15 with both UVA/B protection.
Seek out shade when you are outside.
As well, adults are encouraged to serve as role models for children. It is important that sun safety becomes part of the normal daily life. Adults can actively promote sun safety by taking the same precautions encouraged for children.

 Artificial Tanning: The Canadian Cancer Society states that No Tan is a Safe Tan. Artificial Tanning is not a safe alternative to natural tanning. Exposure to UVA and UVB radiation from the sun or from tanning lamps can lead to sunburn which damages skin and increases the risk of skin cancer. In their discussion of Tanning Lamps, Health Canada reports that it is important to know the risk of all types of UV radiation exposure and, if you decide to go ahead with tanning, to take steps important to reducing your risk.
