Risks Of Overexposure
· Non-melanoma
· Melanoma
· Actinic karatosis
· Polymorphous light eruption (PLE)
· Sunburn
· Photoaging
Salon owner/operator and client education is the number one factor that
can and will diminish the chances of risk during the tanning process.
As with any process involving UVR exposure, it is vital to stress moderate,
sensible and responsible tanning and consistent use of approved eye protection.
Risks of Overexposure
The indoor tanning industry believes that the advantages of sensible,
moderate and responsible exposure to ultraviolet radiation (UVR) far outweigh
the minimal and manageable risks involved.
However, overexposure, which is defined as a UVR dose sufficient to cause
erythema, should be avoided. Repeated overexposure is believed to cause
eye and skin injury and allergic reactions and increase the risks of developing
photoaging of the skin, dryness, wrinkling, and (sometimes fatal) skin
cancer.
There are two categories and three main types of skin cancer:
1. Non-melanoma skin cancer
A. Basal Cell Carcinoma (BCC) occurs in the deepest layer of the epidermis
and it is named for the skin cell in which it arises. In 1998 there were
an estimated 765,000 new cases (incidence) of BCC diagnosed in the United
States and 300 deaths (mortality) for an incidence to mortality ratio
of 2,549 to 1.
Signs- Basal cell carcinoma usually appears as a smooth, waxy or pearly
bump that grows slowly and rarely spreads.
B. Squamous Cell Carcinoma (SCC) occurs in the upper layers of the epidermis.
In 1998 there were an estimated 190,700 new cases (incidence) of SCC and
900 deaths (mortality) for an incidence to mortality ratio of 212 to 1.
Signs- Squamous cell carcinoma causes a firm, nodular or flat growth
with a crusted, ulcerated or scaly surface on the face, ears, neck hands
or arms.
2. Melanoma
A. Cutaneous Malignant Melanoma (CMM) are more rare but are aggressive
and can be fatal. In 1998 there were 44,300 new cases (incidence) of CMM
and 7,300 deaths (mortality) for an incidence to mortality ratio of 6.1
to 1.
Signs- Melanoma often appears asymmetrical, irregularly bordered and
with a diameter larger than the head of a pencil (about ¼ of an
inch).
Medical Help Regarding Skin Cancer
If you notice a new growth, change in skin or sore that doesn’t
heal in 2 weeks, see your physician. Don’t wait for pain; skin cancers
are usually not painful. The cure rate for skin cancer is high if you
receive treatment early
There are several other skin conditions that have been associated with
overexposure to sunlight (ultraviolet radiation). They are:
Actinic (solar) keratosis (AK). A horny growth or callosity associated
with middle-aged or elderly individuals with fair complexion. AK is a
premalignant condition that may give rise to squamous cell carcinoma and
is linked to repeated overexposure to sunlight.
Polymorphous light eruption (PLE). A common disorder that is characterized
by a delayed abnormal response to sunlight, usually a rash or eruption,
that is found on UVR-exposed areas of the skin. Women are four times more
likely to experience PLE symptoms than are men. Additionally, about 5%
of the public is prone to an outbreak of PLE. The typical onset is 1 to
24 hours after exposure and the condition usually resolves itself within
seven to ten days.
Sunburn (Erythema)
This condition is an acute reaction in the skin following overexposure
to UV radiation. UVB accounts for most sunburn reactions. Symptoms of
sunburn usually appear within a few hours after exposure, bringing pain,
redness, swelling and occasional blistering. Because a large area of the
body is often effected after overexposure, a sunburn can cause headache,
fever and fatique.
Sunburn may not slow you down too much, but a lifetime of overexposure
to UV radiation can damage your skin and increase your risk for skin cancer.
If you have sever sunburn or immediate complications (rash, itching or
fever), contact your physician.
Photoaging
The term photoaging is a relatively new one. Utilized to describe skin
changes that result from chronic UVR overexposure that mimic the physiologic
aging process. Photoaged skin is typically thickened and has increased
numbers and activity of skin cells. There is a degeneration of collagen
fibers and an increase in elastin of the skin.
Photaged skin appears rough and thickened, with wrinkling and furrowing.
It is dry to the touch and may have a yellowish color associated with
brown hyperpigmentation.
