— -- intro:Most people know very little about their thyroid at all, let alone the health problems that can affect it. (The thyroid gland is in your neck, by the way.) But thyroid cancer is being talked about today more than ever, thanks to celebs like Brooke Burke-Charvet and Sophia Vergara, who both had the disease, and Robert Ebert, who died in 2013 after fighting thyroid and salivary cancer for years.

It’s also being diagnosed now more than ever, as well: Rates of thyroid cancer have increased three-fold in the last three decades in the United States; by some measures, it’s considered the fastest-growing cancer among women. For Thyroid Cancer Awareness Month, we talked with Hossein Gharib, M.D., professor of medicine at the Mayo Clinic College of Medicine and President of the American Thyroid Association. Here’s what he thinks everyone should know about this disease.

The increase in diagnoses is mostly due to better detection of small papillary thyroid cancers by ultrasound and biopsy technology, says Dr. Gharib. This sounds like a good thing, but it’s not without controversy: “Some consider this overdiagnosis of disease that is not clinically important,” he says, noting that many thyroid cancers are slow growing and not life-threatening. “Therefore, some patients undergo unnecessary treatment.”

19 Signs Your Thyroid Isn't Working Right

But thyroid cancer is usually symptom-free, says Gharib. “It is commonly diagnosed when a patient presents with a thyroid lump or nodule,” he says. “Nodules are usually discovered incidentally, by the patient or by a doctor.”

In fact, the 25-year survival rate for patients with papillary thyroid cancer, the most common type, is 95%.

The type of cancer is important, too: “Follicular thyroid cancer accounts for only 10% but has a more guarded prognosis,” says Dr. Gharib, “and anaplastic thyroid cancer, a rare tumor, is very aggressive with very high mortality.”
