The short explanation
A swelling that moves up when you swallow is usually from the thyroid gland, because the thyroid is attached to the windpipe. The next steps are usually a blood test for thyroid function, mainly TSH and free T4, and an ultrasound of the neck to see whether the whole gland is enlarged, which is called a goitre, or whether there are one or more nodules. Depending on the scan, your doctor may suggest antibody tests or a fine needle test of a nodule.
What depends on your situation
The parts of this that change from woman to woman. Uncertainty is stated, not hidden.
- The blood test shows whether the thyroid is making too much, too little or the right amount of hormone. The ultrasound shows the size, structure and any nodules. Most thyroid swellings in young women are not cancer.
- In young women, common causes include autoimmune thyroiditis, iodine-related goitre and benign nodules. Your doctor will ask about symptoms such as weight change, palpitations, tiredness and period changes.
- At a government hospital, these tests are often available at low cost; private labs vary in price.
What this answer cannot determine
The boundary of online education. These need a clinician who can see you.
- This answer cannot tell you what is causing your swelling. Tests and an examination are needed.
Questions for your clinician
Take these with you. You can add any of them to an appointment card.
- Which blood tests and scan do I need?
- Is it a goitre or a nodule?
- Will I need a needle test?
- What symptoms should I report before my next visit?
