Thyroid cancer facts
The incidence rate of thyroid cancer has more than doubled in the population since 1970, according to Health Canada, and women are three times more likely to be diagnosed than men. Between 2004 and 2019, thyroid cancer rose 5.9% in women each year.
The causes of thyroid cancer are unknown, with research only beginning to isolate some environmental factors. However, it is solidly established that people are more at risk if they were ever exposed to radiation. Learn thyroid facts everyone should know.
Symptoms to be aware of

- a lump or swelling in the front of the neck
- swollen lymph nodes in the neck; this can often take the form of a large mass in the neck or as multiple swollen nodes in the thyroid
- hoarseness or other voice changes, including difficulty speaking in a normal voice

How to do a thyroid self-exam
This technique is recommended by M. Sara Rosenthal, author of The Thyroid Sourcebook and director of the bioethics program at the University of Kentucky.
1. Hold a mirror to your neck, focusing on the area just below the Adam’s apple.
2. Tip your head back slightly.
3. Take a drink of water. Normally, as you swallow, your windpipe rises and then goes back to its normal position.
4. As you swallow, look at your neck. Check for any bulges or a protrusion in the area. Repeat this a few times to be sure you’re all clear. If you’re not sure, see your doctor.
