The importance of thyroid symptoms you can see
Andrei_R/Shutterstock Most thyroid cancer is found by accident—doctors usually find it when patients are getting ultrasounds, CT scans, or MRIs for an unrelated reason. The nodules themselves are rarely noticeable, says Michael Tuttle, MD, an endocrinologist with Memorial Sloan Kettering Cancer Center. (Check out these other cancers that are hard to detect.) Patients can usually choose to keep an eye on the cancer and make sure it doesn’t get worse rather than getting treatment right away, he says. “I would ignore asymptomatic, millimeter-sized things that you’d only find if you’re looking for it,” he says. “But any signs or anything you can feel in the neck, that would cross over to something you should no longer ignore.” If you have any of these potential thyroid cancer symptoms, ask your doctor if you should get a fine needle aspiration to test for cancer.

Lump in the neck

About 90 percent of thyroid nodules are benign, but if you have a large lump in the front of your neck below the Adam’s apple, pay attention to how it acts. “The trick is it moves up and down when you swallow,” Dr. Tuttle says. “Most other lumps don’t move.”
