CT scans use ionising radiation, which can slightly increase the risk of developing cancer later in life. Explore the link between CT scans and cancer risk. CT Scan (Computed Tomography): Provides detailed cross-sectional images of the kidneys, aiding in the detection and staging of tumors. The additional risk of getting cancer from one CT scan is estimated to be less than one in 2,000. The benefits of these tests, when they're appropriate, far outweigh any radiation-associated cancer risks, and the risk from a single CT scan or nuclear imaging test is quite small.

CT machines do expose patients to ionizing radiation, which over time can damage DNA. Objective To assess the cancer risk in children and adolescents following exposure to low dose ionising radiation from diagnostic computed tomography (CT) scans. How does an MRI scan work? The MRI machine is a large, cylindrical (tube-shaped) machine that creates a strong magnetic field around the patient and sends pulses of radio waves from a scanner. CT scans are vital for diagnosis, but research suggests they may cause 5% of cancers. Yet, many doctors are skeptical of this conclusion. A computed tomography scan (CT scan), formerly called computed axial tomography scan (CAT scan), is a medical imaging technique used to obtain detailed internal images of the body.
