Causes

Often unknown.

Does it spread or run in families?

  • Women
  • Radiation exposure

Neck exam.

Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to an oncologist (cancer doctor), often with a surgeon and a radiation doctor.

Living with it

  • Take thyroid pills the same way every day, often on an empty stomach.
  • Get blood tests as advised.
  • Long-term illness can affect mood. Tell your doctor if you feel down or anxious.

Support groups and helplines

Back to school, work, or sports

  • Most people can keep working or going to school.
  • Ask about changes that help, like extra breaks or a flexible schedule. Workers may be covered by the ADA. Students may get a 504 plan.

Children, pregnancy, and older adults

  • Women: Nodules are more common.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • This condition needs closer checkups during pregnancy. Plan ahead with your doctor.
  • Some cancer treatments can harm a baby. Ask about saving eggs before treatment if you want children later.
  • Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
  • Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
  • Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

For caregivers

  • Go to visits when you can and take notes.
  • Keep a list of medicines, allergies, and doctors in one place.
  • Learn the warning signs that need fast care.
  • Take breaks and ask for help. Caregivers need care too.

Outlook

Most are harmless.

Thyroid cancer is one of the most treatable cancers.

Getting ready for your visit

Bring a list of your symptoms and medicines.

Questions to ask

  • Do I need a biopsy?
  • What does my ultrasound score mean?
