The best way to prevent
all kinds of skin cancer, including melanoma, is to protect yourself whenever
you are out in the sun.
Try to stay out
of the sun during the middle of the day (from 10 a.m. to 4 p.m.).
Wear sun-protective clothes when you are outside, such as a hat that
shades your face, a long-sleeved shirt, and long pants.
Use sunscreen every day. Your sunscreen should have an
SPF of least 15. Look for a sunscreen that protects
against both types of UV radiation in the sun's rays—UVA and
UVB. When you are outdoors for long periods of time, reapply sunscreen every 2 hours.
Use a higher SPF when you are at higher
Avoid sunbathing and tanning salons.
Check your skin every month for odd marks, moles, or
sores that will not heal. Check all of your skin, but pay extra attention to areas that get a lot of sun,
such as your hands, arms, and back. Ask your doctor to check your skin during
regular physical exams or at least once a year.
