3 months

What is life expectancy after thyroid cancer?
Prognosis is the chance of recovery. The 5-year survival rate tells you what percent of people live at least 5 years after the cancer is found. Percent means how many out of 100. Overall, the 5-year survival rate for people with thyroid cancer is
98%
.

most thyroid cancers grow slowly
and can come back even 10 to 20 years after treatment. Your cancer care team will tell you what tests you need and how often they should be done.
Can thyroid cancer spread to the brain?
