Sale of Colon Cancer Diagnostic Tool to Czech Republic

SAN DIEGO, April 30 /PRNewswire-FirstCall/ -- SpectraScience, Inc. (OTC Bulletin Board: SCIE), a San Diego based medical device company, today announced that it has sold one of its WavSTAT(R) Optical Biopsy Systems to the Almeda Company of Prague, Czech Republic. The device will be used at the University of Prague during colonoscopy to determine if tissue is normal, pre-cancerous or cancer.

Generally, doctors search for polyps, which are abnormal growths that stick out from the colon lining and can turn into cancer. However, another type of growth is much more dangerous and harder to see because it is flat or depressed and similar in color to healthy tissue. The WavSTAT uses an optical probe in conjunction with a colonoscope to determine within seconds if these flat or depressed lesions are cancerous or pre-cancer with greater than 96% accuracy.

Michel Vaudry, SpectraScience's Director of International Sales said, "The Czech Republic has one of the highest instances of colorectal cancer in the world. Our Czech partner, the Almeda Company, sees a large opportunity in helping physicians detect these flat 'polyps' at an early stage. In a recent study, it was found that close to 10% of patients had flat lesions, and that these lesions were five times as likely as polyps to contain cancerous or precancerous tissue. The flat or depressed lesions accounted for 15 percent of the potentially cancerous growths found in the study, but were involved in half of the cancers."

Vaudry continued, "The feeling amongst physicians that we have spoken with in the Czech Republic is that the WavSTAT is a wonderful adjunctive tool to aid in early detection of these flat lesions. We are now exploring additions to our export team in other European countries such as Italy, Germany and France."
