Prevention of Melanoma
Avoiding excessive exposure to ultraviolet radiation can reduce the risk of skin cancer. This can be achieved by:
avoiding sunburn
wearing clothes that protect against the sun
using sunscreen with a minimum sun protection factor (SPF) of 15, but preferably SPF 20-30, with 4- or 5-star UVA protection
liberally applying sunscreen about half an hour before going out, and
applying it again after half an hour
reapplying every 2 hours and after swimming to maintain adequate protection
avoiding the highest sun intensity between 11 am and 3 pm by finding shade.
protecting children by keeping them in the shade, with clothing, and by applying SPF 50+ sunscreen
keeping infants out of direct sunlight
Wearing sunscreen is not a reason to spend longer in the sun. Sun exposure should still be limited, where possible. People who work outdoors should take precautions to minimize exposure.
