How serious is a lump on your thyroid?
Most thyroid lumps, called nodules, are not serious, and more than 95% are benign (non-cancerous). However, every lump needs a proper medical check to rule out cancer, hormone problems, or breathing and swallowing issues. Understanding the difference between a thyroid nodule and thyroid cancer is important because their symptoms can be similar. A thyroid ultrasound and, if needed, a fine-needle aspiration (FNA) biopsy help doctors accurately tell the difference.
Facts About Thyroid Lumps
- Common occurrence: About half of all people will get a thyroid nodule by the time they reach age 60.
- Low cancer risk: Only about 5% to 10% of these lumps turn out to be cancer.
- Hormone changes: Some lumps make too much thyroid hormone, causing fast heartbeat, weight loss, and shaking.
- Testing methods: Doctors use a painless ultrasound and sometimes a tiny needle test (biopsy)to see inside the lump.
Warning Signs to Watch For
- Fast growth: A lump that gets big very quickly.
- Hard feel: A mass that feels very hard and does not move when you touch it.
- Trouble swallowing: Food feeling stuck or pain when you swallow.
- Voice changes: Getting a hoarse or raspy voice
