Papillary Thyroid Microcarcinoma

Rodrigo Arrangoiz MS, MD, FACS, FSSO

  • Thyroid nodules are common.
  • Virtually everyone will develop small thyroid nodules (less than 1 cm in size) that can be detected by ultrasound by the time they reach age 65.
  • Most of these nodules do not require any investigation.
  • Nodules that are less than 5 to 6 mm virtually never need further attention.
  • Nodules that are 7 to 10 mm occasionally will exhibit suspicious features that do prompt a needle biopsy (fine needle aspiration).
  • Microcarcinomas are thyroid cancers < 1 cm in size:
    • These microcarcinomas typically are papillary thyroid cancer:
      • The most common type of thyroid cancer.
        • There remains much debate among thyroid cancer specialists about how to manage these small cancers.

  • Microcarcinomas (less than 1 cm) are very common and may occur in up to 1 in 10 adults in the United States:
    • The majority of patients are unaware of their existence since they do not cause any symptoms.
    • Most microcarcinomas are discovered accidentally, typically during an imaging study that includes the neck done for unrelated reasons.
      • The prognosis of these small cancers is excellent, but no matter how small the cancer may be, the word “cancer” can be scary.
  • There is a 10% risk of the tumor growing about 3 mm in size in 10 years:
    • Which means, approximately 90% of small thyroid cancers do not grow.
  • There is a 4% risk of the tumor spreading to lymph nodes around the thyroid at 10 years:
    • Which means, approximately 96% of the tumors do not spread.
  • Since the vast majority of thyroid microcarcinomas will not cause any health risks during the patient’s life, doctors believe that there are 2 correct approaches to managing these tumors:
    • Surgical excision versus active surveillance.
  • The risk of dying from a small thyroid cancer is extremely small (less than 1 in 1,000 people).
