We know from the pan-Canadian lung cancer screening study that the cost of screening one person per year is about $225. When we go to more remote communities such as those of the first nation people, because they're very sparsely populated it's very difficult for them to go to a large city to get a CT scan done.
One solution is to do what the Japanese have been doing for over a decade. It's to do a mobile CT scan. In the same scanner, we can screen for lung cancer and use the same CT scan to diagnose other diseases without the patient travelling to a major medical centre. In the same mobile units, we can have counsellors to help people to stop smoking.
I want to mention that we can now have technology to feed the CT scan into software to display what the lung looks like if you have COPD or emphysema, as well as to show whether the patient has calcification of the coronary artery. These are very potent visual images to show people what their health status is and, if people are still smoking, would facilitate smoking cessation.
