Soon, diagnosing lung cancer will be possible even if the lymph or growth is smaller than one centimetre.

The pulmonary and critical care medicine department of the King George’s Medical University is working on a method through which a blood sample would tell whether or not a patient had cancer . This would be easier and more convenient than the conventional method of taking a sample from the lung for biopsy.

“At present we are matching the samples taken under the conventional method with the effect of ribonucleic acid (RNA) in the blood samples,” said Dr Ved Prakash, who is working on the idea along with Dr Shailendra of the Centre for Advanced Research, KGMU.

He said the test method being developed by them would take a day to diagnose cancer, unlike the conventional method that took weeks.

Explaining the new method, Dr Ved said, “Instead of biopsy, we take blood and selected markers (specific protein) that have not been used to detect disease anywhere till now. There are 250 markers in blood that can be studied. In fact, we have identified markers that can be used globally.

“We will see if there is the same result from RNA in the blood serum, as shown through conventional method. Then our process will establish that selection of markers can be an effective diagnostic tool,” he said, adding: “Once we are able to establish the blood markers as indicators of cancer, it will be a change in diagnosis.”

The team has studied results from 80 patients so far .


The World Cancer Day was observed at the Super Speciality Cancer Institute, CG City where an awareness programme was organized by the medical faculty of the institute. The programme was attended by members of the general public, construction workers on the premises of the institute and hospital staff.

Among those who addressed the public were the medical superintendent of the hospital, Prof HS Pahwa, who spoke on the importance of World Cancer Day, Prof Sabuhi Qureshi, who spoke on the significance of a healthy life style and prevention of cancer and Dr Tapas Singh, who spread awareness on warning signs of cancer and how to detect it early. Substance abuse and its relation to cancer was discussed by Dr Sharad Singh. The programme ended on a positive note and was well appreciated by all present.
