British researchers try to detect metal isotope techniques for blood tests and found that changes in the human body can be used for early diagnosis of zinc in breast cancer. Scientists use this outcome is expected to develop a more convenient method of breast cancer blood test. Recent studies have found that breast cancer tissue zinc content will rise, but the scientific community to which the mechanism is not clear, it can not be a non-invasive detection through regular blood tests.
Researchers at Oxford University, Imperial College and other institutions in the Royal Society of Chemistry journal “Metal omics” the report says, they use metal isotope detection techniques commonly used in the study of climate change and planet formation, detection of five breast cancer patients and five healthy human serum, and cancer than breast cancer tissue samples were analyzed launched. Studies have shown that the use of this technique to detect changes in blood levels of zinc, can accurately detect early breast cancer.
In this variation, the breast becomes organization sulfur proteins play an important role in the body’s ability to deal with zinc affected. The researchers said that using this technique to detect trace metals in the blood, the clinical application of existing technology than a hundred times more accurate, and therefore easier to detect subtle changes. This discovery not only helps to develop non-invasive methods for early diagnosis of breast cancer, but also for the study of breast cancer cells provides a new tool. In addition to breast cancer, the next step they will study the changes in other cancerous tissue in the metal trace elements.
