Glasses help surgeons detect cancerous tissue during surgery




U.S. scientists have developed a glasses that must to detect. Cancerous tissue during surgery easier for surgeons This should ensure that less healthy tissue needs to be excised.

The glasses causes cancer in the sight of doctors are colored blue. Before a substance to the patient must moreover be injected that specifically recognizes cancer cells, according to scientists at the Washington University School of Medicine. The injected substance is fluorescent and emits light that can not be seen. With the naked eye

From experiments in mice show that the concept with fluorescent surgeons can help cancer cells: it was found to be in order to detect tumors with a diameter of 1 mm as possible in the glasses. However, the scientists want to still ensure that the substance remains fluorescent longer present in the cancer tissue: this are currently experiments done with another fluorescent substance which is to be ultimately approved by the authorities.

During surgery in cancer patients in the removal of the tumor are removed. Slightly healthy tissue That happens because it is generally, it is difficult in spite of the use of microscopes, to see where the limit of healthy and tumor tissue is located. With the glasses should be able to be cancerous tissue, which could lead to fewer follow-up operations and less healthy tissue excised. Therefore better detection of
