This is a pilot study to compare two ways of managing newly identified thyroid nodules that are likely to be cancerous based on ultrasound result and which under usual care would undergo immediate biopsy.

The main goals of this pilot study are 1) compare anxiety at 6 months in each treatment arm using the validated instrument Anxiety-CA, 2) measure thyroid quality of life in each treatment arm

Participants will be randomized to one of two groups:

1. immediate biopsy (usual care)
2. Active monitoring (serial ultrasound based monitoring and close clinical follow-up)

Inclusion Criteria:

• Participants must be ≥18 years of age.
• Participants must be able and willing to provide informed consent or have a surrogate capable of providing same.
• Participants must be absent of symptoms referable to the nodule: dysphagia or nodule physically visible and/or bothersome to patient.
• Participants' thyroid nodule must have a TI-RADS rating of 4 or 5.
• Participants thyroid nodule must be ≤2 cm in largest diameter.
• Participants must be being considered for biopsy.
• Participants with a prior history of papillary thyroid cancer are eligible.

Exclusion Criteria:

Patients who fall into one of the following categories will NOT be eligible for this study:

• Adults who are unable to provide informed consent.
• Patients for whom biopsy is not a consideration.
• Patients with a prior history of thyroid cancer other than papillary thyroid cancer.
• Patients with a history of radiation to the neck.
• Patients who are athyroidal (thyroid gland has been removed or patient has only lingual thyroid tissue).
• Patients who have ultrasound evidence of one or more of the following:
• Airway invasion of the nodule.
• Nodule adjacency to/invading the recurrent nerve.
• Extra-thyroidal invasion by the nodule.
• Patients who have metastasis to cervical lymph nodes (confirmed by needle biopsy if ultrasound suspicious), distant metastases, if identified) testing not required, not usual care)
• Patients who have already had a biopsy of the nodule being considered for inclusion in the study.
