May is Skin Cancer Awareness Month, a time to increase awareness of the importance of the prevention, early detection, and treatment of skin cancer.
More than 90 percent of skin cancers are associated with sun exposure. And since sun exposure adds up day after day, the best option is to create a habit of protection under the sun.
Reduce Your Skin Cancer Risk:
- Seek the shade, especially between 10 AM and 4 PM when the sun is strongest. An extra rule of thumb is the “shadow rule.” If your shadow is shorter than you are, the sun’s harmful UV radiation is stronger; if your shadow is longer, UV radiation is less intense.
- Do not burn. A person’s risk for melanoma doubles if he or she has had five or more sunburns at any point in life.
- Avoid tanning and UV tanning booths. UV radiation from tanning machines is known to cause cancer, and the more time a person has spent tanning indoors, the higher the risk. Those who make just four visits to a tanning salon per year can increase their risk for melanoma by 11 percent, and their risk for the two most common forms of skin cancer, basal cell carcinoma and squamous cell carcinoma, by 15 percent.
- Cover up with clothing, including a broad-brimmed hat and UV-blocking sunglasses. Clothing can be your most effective form of sun protection, so make the most of it with densely woven and bright-or dark-colored fabrics, which offer the best defense. The more skin you cover, the better, so choose long sleeves and long pants whenever possible.
- Use a broad spectrum (UVA/UVB) sunscreen with an SPF of 15 or higher every day. For extended outdoor activity, use a water-resistant, broad spectrum (UVA/UVB) sunscreen with an SPF of 30 or higher.
- Apply 1 ounce (2 tablespoons) of sunscreen to your entire body 30 minutes before going outside. Reapply every two hours or immediately after swimming or excessive sweating.
- Keep newborns out of the sun. Sunscreens may be used on babies over the age of six months, but they should also be protected by shade and clothing. Children are very sensitive to ultraviolet radiation— just one severe sunburn in childhood doubles the chances of developing melanoma later in life.
- Examine your skin head-to-toe every month. While self-exams shouldn’t replace the important annual skin exam performed by a physician, they offer the best chance of detecting the early warning signs of skin cancer. If you notice any change in an existing mole or discover a new one that looks suspicious, see a physician immediately.
- See your physician every year for a professional skin exam.
What to look for
Important warning signs of melanoma include changes in size, shape, or colour of a mole or other skin lesion or the appearance of a new growth on the skin. Changes that occur over a few days are usually not cancer, but changes that progress over a month or more should be evaluated by a doctor. Basal cell carcinomas may appear as growths that are flat, or as small, raised, pink or red, translucent, shiny areas that may bleed following minor injury. Squamous cell cancer may appear as growing lumps, often with a rough surface, or as flat, reddish patches that grow slowly. Another sign of basal and squamous cell skin cancers is a sore that doesn’t heal.
