Laser based diagnosis of skin cancer represents an important medical advancement in the study and treatment of skin based cancers.

Currently, the main technique for diagnosing skin cancer is a biopsy, where a segment of skin is cut and looked at under the microscope. But new medical advances coming from Duke University offer a laser based alternative.

In this laser based methodology, moles and other suspicious skin lesions are examined for their levels of hemoglobin and melanin, which are both early warning signs for skin cancer growth.

Hemoglobin and melanin do not respond to other laser methods, but this new method, developed by Warren Warren, excites these substances through the use of highly controlled laser pulses.

This would enable dermatologists to see more than a millimeter below the skin's surface; more than enough for accurate diagnosis.

This means that people can now be screened for skin cancer simply by being scanned by this special two laser device.

Work is underway to create a compact, office-based unit which dermatologists can use in their offices to provide quick and painless skin cancer screenings.

As the weather warms up, you will naturally sweat. Sweat is the body's way of cooling down.

For some people, though, there is no such thing as a little sweat. These people sweat excessively, the medical term for which is hyperhidrosis.

Hyperhidrosis is more common than you might think, as it is estimated to impact 2-3% of Americans.

These problems tend to start between the age of 13-17 years, and, left untreated, these problems may continue throughout life.

There are many reasons for excessive sweating, including neurologic, metabolic, and other systemic diseases.

Heat and emotion may trigger sweating, but, for most people with this condition, they sweat all the time, regardless of the weather or of how they feel.

Generally, hyperhidrosis is treated by over the counter antiperspirants, and then prescription strength ones.

If neither of these work, sufferers may undergo iontophoresis, which sends electricity under the skin to decrease the sweat gland's activity.

Oral medications may also be used, followed by Botox.

In the most severe cases, surgery and aluminum chloride hexahydrate are the lines of final defense.

If you suffer from excessive sweating, you may want to consult your physician for treatment.
