Thyroid Disease
Nodules, goiter, cancer, and surgical decisions
Most nodules are benign — ultrasound and cytology triage who needs surgery.
Thyroid nodules, goiter, and thyroid cancer are evaluated with ultrasound risk stratification, TSH, and fine-needle aspiration (FNA) when indicated. Most nodules never need an operation; compressive goiter, suspicious or malignant cytology, and selected autonomous nodules do. Surgery ranges from lobectomy to total thyroidectomy, with recurrent laryngeal nerve protection and parathyroid preservation as central technical goals. Voice change and hypocalcemia are discussed before surgery, not only afterward. Hormone replacement and calcium monitoring complete the pathway when total thyroidectomy is performed.

Ultrasound triage
Risk stratification guides who needs biopsy.
Cancer pathways
Papillary and other types differ in extent of surgery.
Voice & calcium
Nerve and parathyroid protection are central technical goals.
Aftercare
Hormone replacement and calcium checks when needed.
What to know
Who needs surgery
Cancer, suspicious cytology, compressive goiter, or selected autonomous nodules. “Having a nodule” alone is not an operation.
FNA and risk categories
Cytology (often Bethesda categories) plus ultrasound features decide observation, repeat biopsy, or surgery.
- Key note inside
Risks to discuss
Voice change, hypocalcemia, bleeding, and need for lifelong replacement after total thyroidectomy are part of informed consent.
Extent of surgery
Lobectomy versus total thyroidectomy depends on cancer type, size, contralateral findings, and sometimes molecular/cytology context.
Recovery and hormones
Most patients go home quickly. TSH-guided levothyroxine dosing and calcium checks are scheduled when indicated — not optional fine print.

Appointment / info
Bring ultrasound and FNA reports to the visit — they usually decide observation versus surgery faster than a new exam alone.
