Cat Scans Responsible for 2% of all Cancers

Computed axial tomography Scans: They are responsible for two per cent of all cancers!

CT (computed tomography) scans are the cause of upwards to two per cent of all cancers. The consequences could be much worse among youngsters, who are more susceptible to radiation therapy.

The scans, which appear to particularly cause cancers of the lungs and colon, produce a radiation dose akin to that of the A-bombs that were dropped on Hiroshima and Nagasaki in 1945.

The scan brings forth a radiation dose of approximately fifteen in an full-grown adult, and thirty mSv in a newborn infant child, and since normal treatments are for 2 to 3 scans, the total dose attains forty-five . Survivors of Nagasaki and Hiroshima were exposed to doses somewhat below fifty .

Approximately eleven per cent of all CT scans are done on minors, and researchers worry that, even if they don't get cancer right away, they're still at greater risk as grownups because their radiation load continues to increase.
