DAMNED IF YOU DO… –
March 10, 2025 – A medical test used to detect cancer may actually be contributing to the disease, research suggests. In 2009, researchers estimated high doses of radiation from CT scans were responsible for roughly 30,000 cases per year. Ongoing research indicates as the number of CT scans increases, related cancers will likely rise.
However, experts say they are sometimes overprescribed and performed unnecessarily, potentially because of the money-making opportunities for the hospitals, as the tests are very expensive, or out of doctors’ fears of missing a diagnosis and being sued. She told NBC News: ‘It’s unfathomable. We keep doing more and more CTs, and the doses keep going up.’
Dr Smith Bindman said between two machines, one could be exposing patients to 10 to 15 times higher radiation doses than the other.
She added: ‘There is very large variation and the doses vary by an order of magnitude — tenfold, not 10 percent different — for patients seen for the same clinical problem.”
