A common medical assumption is that medical scans can increase your chances at getting cancer--is this true?
Medical imaging techniques like mammography, X-rays, and CT scans are essential tools for detecting and diagnosing diseases (e.g., breast cancer), and also monitoring treatment progress and health conditions.
These imaging methods use ionising radiation, which can damage DNA. In rare cases, DNA damage from radiation may lead to cancer. This is where the concern lies among people.
However, based on research the risk is minimal due to the low doses used in diagnostic imaging.
For example, a standard mammogram delivers about 110 milligray (mGy) per breast. Factors influencing dose are breast size and tissue density. This is considered low-dose radiation and is clinically safe.
CT scans given involve higher radiation than X-rays or mammograms. Even so though, when used proper, the risks remain low.
Bringing to a conclusion that the benefits of early detection and accurate diagnosis far outweigh the minimal risks.
