What is causing the rise in thyroid cancer?
Background. The rapidly rising incidence of papillary thyroid cancer may be due to overdiagnosis of a reservoir of subclinical disease. To conclude that overdiagnosis is occurring, evidence for an association between access to health care and the incidence of cancer is necessary.
What are the risk factors of papillary thyroid cancer?
- A family history of thyroid cancer.
- A personal or family history of goiters.
- Whole-body radiation for bone marrow treatment.
- Exposure to high levels of radiation caused by nuclear accidents or weapons testing.
