Thyroid Cancer - Special Focus


Special Feature: A first look at the status of thyroid Cancer in Ontario

What is thyroid cancer?
  • Thyroid cancer is a cancerous tumour that starts in the cells of the thyroid.
  • The thyroid is a gland that is located at the base of the neck.
  • The thyroid helps control heart rate, blood pressure and body temperature.
thyroid cancer in Ontario
  • Thyroid cancer is the 8th most common cancer in Ontario.
  • Incidence rates are rising faster than any solid cancer, especially in women and in younger people.
  • In 2013, the number of women diagnosed in Ontario was almost 3.5 times the number of men diagnosed.
  • About 94% of thyroid cancers in Ontario are papillary thyroid cancer, which has a very good prognosis.
  • Thyroid cancer is caught early (stage I) in most people. When cancer is caught early it is easier to treat.
  • Thyroid cancer is mainly treated with surgery, radioactive iodine-131 and thyroid hormone replacement.
  • In 2015, 89% of thyroid cancer patients in Ontario received thyroid surgery within the recommended wait time.
  • About 13% of patients have an unplanned hospital visit 30 days after thyroid surgery, which is lower than rates for other cancers.
  • There is currently a move towards more conservative treatment, such as less-than-total thyroidectomy and people receiving less intense radioactive iodine treatment or even none at all. This will result in a better quality of life for patients.
  • Most patients receive treatment locally, but many still travel to other regions to receive treatment. People should be getting both their surgery and radioactive iodine treatment as close to home as possible.
  • The mortality rate has mostly stayed the same over time, about 0.5 deaths for 100,000 people.
  • The 5-year relative survival ratio for thyroid cancer is 95% for males and 99% for females.
  • Thyroid cancer has the highest survival rate of any cancer in Ontario.
  • High survival rates and increasing incidence means that the number of thyroid cancer survivors is increasing.
  • People who have been treated for thyroid cancer will need to take hormone replacement therapy and monitor their hormone levels for the rest of their lives to stay healthy and safe.
