X-rays are among the most widely used diagnostic tools in healthcare. They help identify various health conditions, such as bone fractures, lung infections, and problems in the digestive tract.

While X-rays offer many advantages, concerns remain about the potential link between radiation exposure from X-rays and the development of cancer. So, can X-rays actually cause cancer? Find the full explanation below.

How X-rays Work

X-rays function by sending radiation waves through the body. These rays pass through tissues and form an image based on the density of the material encountered.

Dense structures like bones appear white in the resulting image, while softer tissues, such as those in the lungs, appear darker. This non-invasive technology allows doctors to see inside the body without the need for surgery, making it easier and faster to identify health problems.

Radiation and Its Link to Cancer

X-rays use ionizing radiation, which has enough energy to disrupt atoms by removing electrons. When the body is exposed to X-rays, a small amount of radiation is absorbed by the cells. This exposure can potentially damage cellular DNA. If the body fails to repair this damage properly, mutations may occur, and over time, these mutations could lead to cancer.

However, it’s essential to understand that the radiation dose from a single diagnostic X-ray test is generally very low.

Many scientific studies have evaluated the relationship between medical radiation exposure and cancer risk. Most findings conclude that the low levels of radiation used in X-ray diagnostics are considered safe when applied appropriately and not too frequently.

That said, certain conditions may increase the risk of developing health problems from X-ray exposure:

• Repeated X-rays within a short time

• Radiation exposure during early childhood or pregnancy, as these groups are more vulnerable

• High-dose exposure, such as in radiation therapy used to treat cancer

Because some people are more sensitive to radiation, extra caution is advised for the following groups:

• Pregnant women, especially in the early months of pregnancy. The growing fetus is more susceptible to DNA damage from radiation.

• Children, whose developing bodies are more affected by radiation exposure than adults.

• People with frequent exposure, such as those who have undergone many X-rays or CT scans, may face risks from cumulative radiation.

Despite these considerations, X-rays remain a valuable and safe tool when used correctly. In fact, the medical advantages of X-rays far outweigh the potential risks, especially when the test is needed to make an accurate diagnosis. Doctors always weigh the potential benefits and will use the lowest possible radiation dose necessary to protect the patient’s safety.

If you still have concerns about getting an X-ray, you can consult your doctor for a more detailed explanation. You may also use the Ai Care app, available on the App Store and Play Store—for medical consultations.
