How Much Radiation Does a Mammogram Deliver Compared to a Chest X-ray?
A mammogram is a highly effective screening tool for breast cancer detection. However, many women worry about the radiation exposure from the procedure. In reality, the radiation dose from a mammogram is very low and safe.
Radiation Exposure: Mammogram vs. Chest X-ray
- Mammogram (1 session): 0.4 millisieverts (mSv)
- Chest X-ray (1 session): 0.1 millisieverts (mSv)
A single mammogram is equivalent to about 4 chest X-rays in terms of radiation exposure.
Radiation Exposure in Everyday Life:
- Natural radiation exposure per year: ~3 mSv
- Long-haul flight exposure: 0.1 - 0.3 mSv
Since the radiation dose from a mammogram is significantly lower than the annual natural exposure, it poses minimal risk to health.
Why Is a Mammogram Important?
- Detects breast cancer at an early stage, before symptoms appear
- Increases the chances of successful treatment
- Recommended for women aged 40 and above to undergo screening every 1-2 years
