London, 1 cancer killer in the world, lung cancer can now be detected early, accurate and inexpensive. So far, many sufferers are not helped because of late detection. Now, there are inexpensive tools and accurate by using nano particle technology.
A sensor made of nano particles of gold can detect possible cancer of the lung and the patient's breath became the latest alternative diagnosis before the patient has a tumor or lung cancer.
According to the developers of these tools, the price offered for that detector can be relatively cheap and accessible by the doctor or hospital and with 86 percent accuracy rate.
By using the sensor technology of gold nano particles, the tool can detect specific components or Volatile Organic Compounds (VOC) in the breath of someone who has the risk of lung cancer.
Previously, the breath test to detect the existence of the VOC never applied in the medical world in 2006, using trained dogs who can smell a component of cancer in one breath, but a lower accuracy level.
Lung cancer currently ranks first of this type of cancer that causes the most deaths in men and women.
Because the symptoms are vague and not really felt, the patient was often missed, and finally when they have been dealt with medical experts can not be saved anymore.
"Conventional diagnostic methods for lung cancer are currently tend to be expensive and is less accurate, even tumors was sometimes not detected. But with the latest tools now, the risk of lung cancer can be detected with more sensitive, efficient and effective because it is portable, "said Hossam Haick, one of the researchers who wrote his findings in Nature Nanotechnology, as reported by Reuters on Monday (31.8.2009).
Currently, lung cancer kills 1.3 million people each year, only 15 percent of patients have survived over 5 years since the late deteksinya.
