Everyone must have gone through an X-ray test at least once in their lifetime. It can help doctors see inside the body and determine what is actually happening. As this technique is still widely accepted in healthcare, you may doubt its safety. This is why staying aware can help you understand your treatment.
How do X-rays work?
Doctors still use X-rays as their primary technique for examining the body’s condition. For this, they may use X-ray radiation and pass it through your body. These X-rays are then absorbed by the bone and different tissues that are targeted for examination. Structures, like your bones, absorb more of these X-rays and usually appear lighter in the final image. On the other hand, X-rays that pass through your soft tissues may appear a little darker.
Do X-rays increase cancer risk?
Medical imaging uses a small amount of ionizing radiation, which is different from higher-energy gamma rays. The radiation during an X-ray test is usually kept very low. A chest X-ray delivers about 0.1 mSv of radiation, which is roughly equivalent to the amount of natural background radiation a person receives over 10 days. While repeated exposure to X-rays can still cause cancer over time, the risk from an occasional diagnostic X-ray is considered extremely small.
Myths and facts about X-rays
Myths:
A single X-ray is likely to cause you cancer.
X-rays should always be avoided.
X-rays can make you radioactive.
Every imaging test can expose you to the same amount of radiation.
Pregnant women should never consider an X-ray test.
Facts:
Your risk factor from an occasional X-ray can be really low.
X-rays can help doctors detect your illness in its early stages.
X-rays can never make you radioactive, as they don’t get trapped inside your body once the machine is off.
Doctors can use different imaging tests according to your medical condition.
Doctors only use X-rays in emergencies during pregnancy and also ensure safety by using heavy lead aprons to shield the abdomen.
When the benefits outweigh the risks
The information doctors get about your health through an X-ray test is more important than the little risk associated with it. These images can show infections, broken bones, or any other concerns that need quick attention. Early detection could be very difficult for doctors if these images didn’t exist.
How to minimize X-ray radiation?
While the chances of cancer from a single X-ray are very low, radiation from different sources can increase the risk. This is why an X-ray should only be done if you have the right medical reason to do it. If there is really a need for radiation tests, ask doctors if they can provide some shielding to protect your body from being damaged. You can also check radon levels at home with the help of a professional and lower the exposure risk.
Staying aware of your treatment
Concerns before any medical procedures are very natural, but awareness is what matters the most. Awareness can keep you informed about the treatment, so you can focus on the facts instead of unnecessarily stressing.
