Thyroid Cancer

About this Cancer

Thyroid cancer is a lot more common in women, accounting for over double the number of male diagnoses, and ranking 7th most common cancer for women.

According to the CCS, it is estimated that in 2024, 6,600 Canadians will be diagnosed with thyroid cancer, of which 2,000 are men and 4,700 are women. The cancer ranks at 12 overall, on a downtrend compared to previous years.

A small number of patients die from the cancer, estimating that 280 will pass, of which 130 are men and 150 are women.
