What it is
Thyroid cancer develops in the thyroid gland at the front of the neck. The most common sign is a painless lump or swelling in the neck; less often there may be a hoarse voice, difficulty swallowing, or swollen neck glands. Most thyroid lumps are not cancer, but a lump should always be checked. Thyroid cancer is more common in women and can occur at a range of ages. The most frequent types grow slowly and have an excellent outlook, with high cure rates; rarer types behave more aggressively. Diagnosis usually involves examination, an ultrasound scan, and often a needle sample from the lump.
How it is treated
Treatment depends on the type and stage. The main treatment is usually surgery to remove part or all of the thyroid gland, sometimes with nearby lymph nodes. Some people then have a treatment using radioactive iodine to destroy any remaining thyroid tissue or cancer cells. Because removing the thyroid affects hormone production, lifelong thyroid hormone replacement is taken, which also helps prevent recurrence in some cases. Most people with the common types do very well. Care is coordinated by a specialist team with long-term monitoring.
