According to a new report baseline CT screening could prove beneficial and effective in the detection of lung cancer among people that have a history of being exposed to asbestos, which is a potentially deadly substance and a known carcinogenic. Researchers state that this method of screening could benefit those at high risk of developing lung cancer or mesothelioma due to asbestos exposure.

The research was carried out by Italian researchers, and the findings were published in the latest edition of The Oncologist. The results suggest that this type of screening could aid the early detection of lung cancer in those exposed to asbestos. The researchers now want to continue investigations to see whether this type of screening could also help in the early detection of the asbestos related cancer, mesothelioma.

As part of the study screening was carried out on over one thousand people that had been exposed to asbestos. Chest X-rays found non-calcified nodules in just four percent of those screened, but CT screening found these nodules in forty four percent of those screened. The CT screening also enabled researchers to pick up on nine cases of early stage lung cancer, none of which were picked up on chest x-rays.

The patients affected by the tumors actually managed to get the tumors removed before they were even detectible by chest x-rays. However, the CT screening also gave eleven positive results that turned out to be false according to the results of the study.
