It’s just a tan
One person dies of melanoma every hour
(every 57 minutes)
Melanoma is the most common form of cancer
for young adults 25-29 years old and the
second most common form of cancer for young
people 15-29 years old.17
Sustaining 5 or more sunburns in youth
increases lifetime melanoma risk by 80
percent
On average, a person’s risk for
melanoma doubles if he or she
has had more than five
sunburns.19
People who first use a tanning bed before
age 35 increase their risk for melanoma by
75 percent
More people develop skin cancer because
of tanning than develop lung cancer
because of smoking
One indoor UV tanning session increases
users’ risk of developing squamous cell
carcinoma by 67 percent and basal cell
carcinoma by 29 percent.
• What does
Tanning do?
• Wrinkles
• Increases the
enzymes that
break down
collagen
(structure of skin
cells)
• Sagging skin
• Breaks down
elastin (allows
skin to bounce
back)
• Age spots
• Cells that contain
melanin enlarge
and cluster
together
• Rough/Dry skin
• UVA/UVB
damages collagen
and elastin
water escapes
easier, light
absorbed so
duller
• Spider veins
• UV dilates them
and brings to
surface
• Eye probs
• Early cataracts
• Skin Cancer
So what actually happens
When you burn?
First let’s look at your skin…
Reactive
molecules
w/Oxygen
 Very
chemically
reactive 
important
for cell
signaling
and
homeostasis
Pyrimidines!
Pyrimidine Dimers…
Base Modifications
So how do I protect myself?
• Be safe in the sun!!
• Happy Summer!!!
