Heart Scans Might Increase the Risk of Cancer
The Canadian researchers from the Research Institute of the McGill University Health Center (MUHC) in Montreal, observed that heart patients who are subjected to the low-dose radiation from the cardiac imaging might be at an increased cancer risk.
The researchers studied the data from about 82,861 patients who had survived a heart attack between 1996 and 2006. These patients did not have any history of cancer. 77% of these patients had undergone at least one of the cardiac procedures with the low-dose radiation like the nuclear scan or CT angiography. During the follow-up, about 12,020 cancers were detected among these patients. 2/3rd of the cancers affected the chest, abdomen and the pelvic areas.
The researcher found a link between the exposure to the low-dose radiation from the cardiac imaging and the risk of developing cancer. The reports question the safety of the patients undergoing the therapeutic procedures. The study is published in the Canadian Medical Association Journal.
