Oral cancer - diagnosis by the dentist
A new test being developed by researchers at the University of Sheffield and Sheffield Teaching Hospitals NHS Foundation Trust can be conducted by the dentist and can accurately tell a patient in just 20 minutes, if he has oral cancer.

At present, a suspicious lesion in the mouth involves the use of a scalpel and a biopsy and off-site laboratory tests and results can take up to a week. The new test involves removing cells with the help of a brush, then placing them on a nano biochip, and inserting the chip into an analyzer. This quick test will help in reducing waiting time, number of visits, and also costs.

This test uses some of the latest techniques in microchip design, nanotechnology, microfluids, image analysis, pattern recognition and biotechnology.

This technology will enable doctors to screen suspicious lesions in the mouth and separate non cancerous lesions from those where there is risk of cancer or where it has already developed. It will also change the survival rate of oral cancers, which are at present not detected early enough.

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
