Diagnose cancer : Cancer diagnosis test in 10 minutes at home
Cancer diagnosis test in 10 minutes at home
Experts have discovered various ways and methods to diagnose and treat the cancer of the giant deadly diseases, the most recent of which is an interesting invention for diagnosing cancer at home at a low cost.
The use of saliva in this method is the most effective material for rapid diagnosis of cancer.
Methods of diagnosing cancer by testing saliva
Professor David Wang, a professor at California State University, introduced the new test at the American Scientific Advances Association’s annual meeting in Washington.
Professor Wang and a team of researchers working with him found that there were fragments of messenger RNA in the saliva that could indicate the formation of cancer, so they sought to use this finding. Develop a “fluid biopsy” test to diagnose cancer with saliva.
According to Professor Wang, a drop of saliva contains so much information that it can be detected as soon as the cancerous tissue begins to grow:
“With just less than a drop of saliva, this test can be done in 10 minutes. It can be done while you wait in the doctor’s office.”
“The advantage of our method is that it is painless and bleeding-free. If there is a valid method for early assessment of cancer risk, people can also do it in a pharmacy or dental office. The most important thing is early diagnosis.”
Professor Wang hopes that in the future this test can be used to diagnose multiple cancers at the same time.
At present, biopsy of the affected tissue is the most definitive method of diagnosing cancer, and if the biopsy is done and the DNA of the cancerous tissue is identified, a blood test can be used to check for cancer to spread to other tissues in the body (metastasis).
However, the initial diagnosis of cancer with a blood test is not currently possible.
According to the researchers who developed the liquid sampling, the accuracy of this method was “almost perfect” in the initial trials.
Researchers hope the test will be available in four to five years.
