Thyroid cancer

By Cura Editorial Team ·

Most thyroid cancers are highly treatable, and small papillary cancers may not need immediate surgery — active surveillance is a real option now.

What to know first

  • Papillary is the most common type and generally has excellent outcomes.
  • Small (<1 cm) low-risk papillary cancers may be safely watched, not immediately removed.
  • Molecular testing on biopsies can avoid unnecessary surgery for indeterminate nodules.

When to see a doctor

  • A new lump in the neck or a nodule felt on the thyroid
  • Persistent hoarseness or a change in the voice
  • Difficulty swallowing or a feeling of pressure in the neck

What's new in thyroid cancer treatment (2026)

Recent approvals and trial results — and the questions to ask your oncologist about whether any of it applies to you. Not every option fits every person.

Full approval for RET-targeted pill

The FDA granted full approval to selpercatinib (Retevmo) for advanced RET fusion-positive solid tumors, including some thyroid cancers.

May apply to: RET fusion-positive advanced thyroid cancer

Ask your oncologist:

  • Has my tumor been tested for RET changes?
  • Would a targeted pill be an option for me?

Pre-surgery treatment shrank aggressive thyroid tumors, in a trial

In a phase 2 trial, dabrafenib, trametinib, and pembrolizumab before surgery allowed 83% of patients with BRAF-mutant anaplastic thyroid cancer to have their tumor removed.

May apply to: BRAF V600E anaplastic thyroid cancer

Ask your oncologist:

  • Is my tumor BRAF-mutant?
  • Could treatment before surgery help in my case?

Frequently asked questions

What are the early warning signs of thyroid cancer?

The signs that most often lead to a thyroid cancer diagnosis are: a new lump in the neck or a nodule felt on the thyroid; persistent hoarseness or a change in the voice; difficulty swallowing or a feeling of pressure in the neck. Any of these lasting more than a couple of weeks is worth a same-week appointment, even though most turn out to be something else.

When should I see a doctor about possible thyroid cancer?

See a doctor promptly if a symptom is new, persistent, or getting worse rather than better. Describe when it started, how often it happens, and what makes it better or worse — that detail is what decides whether you get imaging or testing at the first visit.

What should I know first about thyroid cancer?

Most thyroid cancers are highly treatable, and small papillary cancers may not need immediate surgery — active surveillance is a real option now. Papillary is the most common type and generally has excellent outcomes. Small (<1 cm) low-risk papillary cancers may be safely watched, not immediately removed. Molecular testing on biopsies can avoid unnecessary surgery for indeterminate nodules.

What questions should I ask after a thyroid cancer diagnosis?

Ask what the exact diagnosis is and how it is staged, what the treatment options are and in what order they would happen, what the goal of treatment is, which side effects to expect, and whether a second opinion or clinical trial makes sense for your situation.

Before the first treatment decision

If a start date is on the calendar, or you feel lost between diagnosis and the first infusion, build a first-visit brief on the page: what's known, what's missing, what to ask. Homework, not a treatment plan.

Cura Brief is educational. It is not medical advice, a diagnosis, or a treatment plan. Confirm everything with your oncology team. If this is an emergency, call emergency services. Email is not an emergency line.

After your biopsy or test

Waiting for results is its own kind of hard. Cura has a plain-language guide to what the wait actually means — and what to do while you wait.
