Ask CancerCare

Having an X-ray can be a regular part of yearly health screening and preventative checkups both in the medical and dental worlds, and it is completely reasonable to consider what precautions should be taken. When you go in to have an X-ray, you encounter several people on your medical team along the way such as radiologists, technicians, nurses, and doctors. The doctor may order the X-ray, the nurse may prepare you for the test, and a technician might set you up with special shields around your neck and abdomen. There may be several opportunities to talk with them about why they are recommending such a scan (taking into account your medical history) and what the risk factors are (such as radiation exposure). Another opportunity to ask questions is when they place the protective shields on you. You may want to ask why they place them on certain areas and not others and what they are specifically shielding.

As for thyroid cancer, it is more likely to develop in people who have been exposed to high doses of radiation, have a history of thyroid cancer in their family, and are 40 years of age or older. But for the majority of people who develop thyroid cancer, the cause is unknown. For more information about thyroid cancer, please visit the National Cancer Institute’s website.

You should speak with your health care team about the possible risks (and precautions that can be taken) when having any procedure, including X-rays. It’s important for you to understand why they are recommending specific procedures and what the risk factors are. X-rays are very different from other scans such as CAT scans and PET scans and your doctor can also talk to you about whether the frequency of these radiology procedures has an effect on your overall radiation exposure risk. Learn more about about radiation exposure and cancer and about different types of imaging tests.

Communication with your health care team is key. How comfortable are you speaking with them about your concerns? Do you feel like you have enough time to ask your questions? Do you feel reassured when they answer your questions? A CancerCare oncology social worker can provide you with support as you consider questions for your health care professionals.
