Every year there are more new cases of skin cancer than breast, prostate, lung and
Colorectal cancer in combination. An American in five get skin cancer in their life.
90% of skin cancers are caused by excessive sun exposure, yet fewer than 33
Percent of adults, adolescents and children sunscreen routinely.
Cancer prevention and early detection techniques could be up to 100,000
Cancer Casesand 60,000 U.S. cancer deaths each year. New technologies in
Evaluation and treatment of sun-damaged skin could have a positive effect on
Changing these statistics.
The same sunny weather that so many tourists and new residents, which attracts
sun-belt increases the risk of skin cancer. The effects of chronic sun exposure
Result in superficial sun spots that are visible and also invisible changes that occur
underthe skin surface. Ultraviolet photography and photodynamic therapy (PDT)
Two of the recent developments, that the treatment and should help in early detection
the two types of precancerous lesions.
Early detection using UV photography
Ultraviolet (UV) photography offers a very useful screening tool to assist qualified
Physician recognize sun-damaged skin, which may not be visible on a routine
Test.
Visual inspection canonly detect changes on the skin surface, but damage caused by
Sun exposure occurs in the outer layer of skin,
The UV camera briefly shines ultraviolet light on the face. UV light is able to
1.5 to 2.0 millimeters penetrate under the visible dead layer of skin and focus on the
actual living portion where sun damage is created. The advantage for the doctor and
the patient is that this technology enables much earlier detection of skin Problems
to develop before entering the pre-cancers that are visible on the skin surface. After
Completion of the treatment plan, the physician should take over another UV photo to verify the
the effectiveness of treatment. UV photography also helps evaluate other skin diseases
including acne, oil balance, hydration, inflammation, growths, fungi, pH, and thin
Skin due to reduced collagen, Tool makes it an ideal problem to evaluate all
> Skin.
After the damage the deeper layers of the skin, superficial signs of sun damage to
eventually appear on the surface. The most common surface lesion is known as
Actinic keratoses (AK). AKs usually as rough or scaly patches. You can also
Flake, crust, and may temporarily disappear and then return.
An AK is most likely to appear on the face, ears, scalp, neck, backs of hands and
Forearms, shoulders and lips – the parts of the body exposed to the most frequently
Sunshine. The scaly patch may be light or dark, brown, pink, red, or a combination of
… or that the same color as the skin.
It is estimated that 10-20% of untreated AKs will develop into squamous cell
Cancer. If treated early, almost all AKs can be eliminated without skin can always
Cancer. If you have AKs, it means that you have suffered damage and Sun have
a higher risk for the development of all types of skinCancer – not just squamous cell
Carcinoma.
The more keratoses a person has, the greater the chance that one or more may turn
Skin cancer arise. People can also up to 10 times as many subclinical (invisible)
Lesions visible, surface lesions. These invisible lesions were not detectable until
the development of the UV camera.
Treatment options
The most common treatment options for AKs have traditionally involved topical
Ointment 5-FU (Effudex), laser treatment or chemical peels. To avoid
prolonged recovery period and possible scarring associated with these techniques,
Photodynamic therapy has been developed.
Photodynamic therapy (PDT) is the treatment of choice for the invisible so deep
Damage as well as the visible pre-cancerous lesions, AK. PDT consists of a two-step
Process that has proven effective in clinical trials. This treatment cleared
100% of AKs in two thirds of patients after treatment.
The first step is the application of a topical solution called Levulan. Abnormal cells
have a much greater affinity for the solution and absorb, while the healthy cells are not
not. The solution is based on an incubation period of anywhere from 15 left
Minutes to 18 hours.
The second step of PDT is a concentrated source application to enable
chemical reaction that destroys abnormal cells. Since the solution is absorbed
only in the injured cells to healthy cells are not affected. This process can lead to
a mild burning sensation during the treatment. Usually, this improves immediately
after treatment and ends within 24 hours.
After treatment, most patients experience mild swelling, redness, and a
Peeling of the AK lesions and the surrounding tissue. Patients the choice of a more
aggressive> Treatment experience more peeling and / or crusting of the damaged
Skin, which dissolves within a week or two. The physician may easily
Severity of these reactions by limiting the incubation period and the amount of
Exposure to the light.
Patients are not prepared to accept a longer recovery time after surgery experience
two workers can choose a mild treatment and rehabilitation of a day or. The
Compromise is that theyrequire more treatments to achieve the same clinical
Results.
In addition to removal of the underground AKS and skin damage, has also PDT
effective in improving the appearance of the skin by greatly reducing moderate to
severe acne (including cystic acne), reducing color splotches, reduction of the fine
Lines and decreasing pore size.
Anyone who currently has, has had, or wants to prevent AKs or pre-cancerous skin
Lesionsshould be assessed and treated using UV photography and photodynamic
Therapy (PDT). "Once a person has been treated successfully using this approach it is
it is recommended to prevent a return for yearly follow-up to future problems.
