Effective Diagnostic Tool For Skin Cancer
Researchers at the Skin cancer Scanning Israeli company has developed a new diagnostic tool for skin cancer that can identify potentially malignant moles with an efficiency of 92 percent, they say, is “much more than any other device currently offers . According to Israeli newspaper Haaretz reported on its website, currently underway in various clinical trials Beilinson Hospital in Petah Tikva, having found that through its fiber optic system it facilitates more accurate information to assist the Early detection of these tumors.
However, researchers are still finalizing the usefulness of this tool and hope that the level of performance reached 95 percent accuracy. “We’ve invested millions of dollars to create an accurate diagnostic method, none of the above have so far been able to replace the doctor,” said Biderman.
In fact, the diagnosis of skin cancer is developing in two stages, with the doctor or dermatologist in charge of making an initial screening and detect which moles are suspected of developing melanoma and confirm the risk through a biopsy. However, the researchers caution that the medical examination is necessary and this is leading many patients to undergo unnecessary biopsies.

Cancer Stem Cell
The cancer stem cell is a hypothetical type of stem cell that would form tumors while the properties of stem cells as self-renewal and the ability to differentiate into multiple cell types. One theory suggests that these cells persist in tumors as a distinct population and cause relapse and metastasis in giving new tumor growth. The development of specific therapies aimed at cancer stem cells in hopes of improving survival and quality of life of cancer patients, especially those who suffer from metastases.
Existing cancer treatments were developed mainly with animal models, where therapies able to promote tumor shrinkage were deemed effective. However, animals can not provide a complete model of human disease. In particular, tumor relapse is exceptionally difficult to study in mice, whose lives do not exceed two years.
