What about Suncreens?
When should sunscreen be used?
Every day if you are going to be in the sun for more than 20 minutes.
The sun’s reflective powers are 17% on sand and 80% on snow.
Even on a cloudy day 80% of the sun’s UV rays pass through the clouds.
How much sunscreen should be used, and how often should it be applied?
One ounce should be applied to dry skin 15-30 minutes BEFORE going outdoors.
Coat skin liberally.
Pay attention to the face, ears, hands and arms.
What type of sunscreen should I use?
Should be water resistant, so they are not easily removed by sweating or swimming.
Should have an SPF of 15 or higher.
Sunscreen and SPF Numbers?
Does SPF 30 have twice as much sun protection as SPF 15?
SPF protection does not actually increase proportionately with a designed SPF number. In higher SPFs such as SPF 30, 97% of sun burning rays re-deflected, while an SPF of 15 indicates 93% deflection and an SPF of 2 equals 50% deflection.
Cancer Prevention
Do not sunbathe.
Avoid unnecessary sun exposure, especially between 10:00 a.m. and 4:00 p.m., the peak hours for harmful ultraviolet (UV) radiation.
When outdoors, use sunscreens rated SPF 15 or higher.  Apply them liberally, uniformly and frequently.
When exposed to sunlight, wear protective clothing such as long pants, long-sleeved shirts, broad-brimmed hats, and UV-protective sunglasses.
Stay away from artificial tanning devices.
Teach your children good sun protection habits at an early age.  The damage that leads to adult skin cancers starts in childhood.
Examine your skin from head to toe at least once every three months.
Have an annual full-body skin exam performed by a dermatologist or primary care physician.
A full-body skin exam should be done once every year.
Any suspicious lesion should be treated and follow up should be with a dermatologist.
Is Melanoma A Serious Disease?
Nearly 75% of all skin cancer deaths are from melanoma.
Advanced melanoma spreads into internal organs and may result in death. If detected in the early stages, melanoma usually can be treated successfully.
What Causes Melanoma?
The most important preventable cause is excessive exposure to the ultraviolet radiation of the sun.
Melanoma has been linked to excessive sun exposure in the first 10 to 18 years of life.
Not all melanomas are sun related. Other possible causes include genetic factors and immune system deficiencies.
