India, May 3 -- AIIMS director Dr Randeep Guleria on Monday warned of the misuse of CT scans and biomarkers by patients having mild Covid-19 symptoms and said that the overuse of CT scans increases exposure to radiation that in turn escalates the risk of cancer.

"No point in conducting CT scans for mild cases; one may find patches in CT scan even if he/she is asymptomatic but may get cured easily 1 #CTScan = 300-400 Chest X-rays! With frequent CTs, risk of cancer in later life increases, for youngsters," Guleria warned, saying that the data by the international atomic energy commission for radiation protection and medicine have shown an increased risk of cancer in later life due to frequent CT scans, especially if done at a young age.
