AIIMS director Dr Randeep Guleria warned against frequent CT Scans, as it would enhance one’s risk of cancer.

He said the data by the International Atomic Energy Commission for Radiation Protection and Medicine, suggested an increased risk of cancer in later life due to frequent CT scans especially at a younger age.

He also warned of the misuse of biomarkers by patients who were suffering from mild COVID-19 symptoms. Guleria said the overuse of CT scans increased the exposure to radiation that in turn, aggravated the risk of cancer.

He said, “No point in conducting CT Scans for mild COVID-19 cases. One may find patches in CT Scan even if the patient is asymptomatic but may get cured easily. One CT Scan is equivalent to almost 300-400 Chest X-rays. With frequent CT Scans, the risk of cancer in later life increases especially for youngsters.”

He gave an example of an asymptomatic COVID-19 patient, whose CT Scan showed nearly 30-40% patches, which eventually got cleared without any treatment.

He said for patients with mild COVID-19 infection, under home isolation and with no problem or decline in saturation, there was no use of a CT Scan as some patches would anyway appear.

He said, “So, there is no point in doing CT scan in mild Covid-19 if the oxygen saturation is normal.” He even warned against the use of biomarkers like CRP, D-Dimer, LDH, Ferritin, etc. saying they were also of no use in case of mild symptoms and normal saturation levels as it only led to panic reactions.

He said that several blood tests for biomarkers were also not needed for patients with mild symptoms/ ones in home isolation if the oxygen saturation is fine and fever is not high and there are no other symptoms.
