DNA blood tests to detect cancer
A technology which identifies disease-specific genetic fingerprints based on DNA fragments that are released into the bloodstream by damaged and dying (apoptotic) cells has been developed by Chronix Biomedical laboratory. DNA blood tests are able to accurately detect early stage breast and prostate cancers.

In their study, Chronix's assays detected and identified DNA fingerprints in the blood that indicated the presence of prostate or breast cancer with 92% sensitivity and 100% specificity, which is far higher than current diagnostic tests.

If this data is confirmed in larger studies, it then has the potential to decrease the rate of false positive and false negative results, which lead to poorer patient outcomes and higher healthcare costs.

Hi Poonam.. indeed a commendable article... Preventive oncology is definitely the need of the hour as far as the indian society is concerned..a lot of money is being spent on clinical trials and drug development.. but cancer is a disease if detected at a very early stage can be treated easily.. Thus the media needs to spread more awareness on preventive oncology.. more people should be encouraged to go for screening tests.In fact free screening should be done in rural areas for cancers related to tobacco. It is good to know about the latest techniques ..only the cost becomes an issue in a developing nation like India

Thank You Preethi. Inspite of sophisticated techniques being available for screening, a lack of awareness and a fear of getting a positive diagnosis often come in way of early diagnosis. Cancer is a silent disease in the very early stages and patients usually report to the physician only during advanced stages of the disease. If high risk individuals would voluntarily get themselves screened a lot of lives could be saved.

Its indeed commendable that latest studies are getting more sophisticated in their treatment- painless and more accurate as they are targeted exclusively on cancer cells, sparing the healthy cells from being affected.
However we as a society should focus and promote HEALTHY EATING, for as the adage goes `An ounce of prevention is better than a pound of cure', besides we definitely have quality of life and we are sure of the end result
