Thyroid cancer often hides in plain sight: Doctor urges women, those with neck symptoms and others to get checked routinely

Thyroid cancer isn’t something people talk about as much as breast or lung cancer, but it’s quietly on the rise. The thyroid is a small, butterfly-shaped gland in your neck, and it plays a big role in regulating your metabolism, energy, and hormones. Because it’s tucked away and doesn’t always cause pain, problems can go unnoticed for years. That’s why thyroid cancer often sneaks up on people.Globally, the numbers are climbing. The World Health Organization reports that thyroid cancer is now the most common endocrine malignancy, and in many countries, rates in women are higher than in men. In India alone, several people are diagnosedevery year, often between their 30s and 50s. Many of these cases are detected only when nodules or lumps in the neck are noticeable—or when doctors catch it during routine checkups for unrelated issues. “Indian studies published by institutions such as the Indian Council of Medical Research and tertiary endocrine centres have repeatedly highlighted that thyroid cancer is often detected incidentally, during scans or check-ups done for unrelated reasons. This points to a deeper issue: awareness is still limited, both among the general public and access to primary healthcare,” Dr Nikhil Mehta - Consultant Onco-Surgeon at HCG Cancer Centre, Mansarovar, Jaipur told TOI Health. And that’s exactly why awareness matters. So many people shrug off subtle neck changes, like swelling, a persistent lump, or even a feeling of tightness. They think it’s just stress, weight fluctuations, or something minor. But these can be early signs of thyroid cancer. "The thyroid gland sits at the base of the neck and plays a vital role in regulating metabolism, energy, and body temperature. When cancer develops in this gland, early symptoms tend to be subtle. A painless lump, mild voice changes, or a feeling of fullness in the throat are frequently ignored or attributed to stress, infection, or lifestyle changes," Dr Nikhil says."A small swelling in the neck is easy to ignore. It does not hurt and interrupt the daily life. For thousands in India, this delay lets thyroid cancer sneak up till it’s urgent. Thyroid cancer is often described as one of the most treatable cancers when detected early. The challenge lies not in treatment alone, but how early the disease gets diagnosed, discussed, and acted upon. Delays in diagnosis remains a major concern, largely due to its asymptomatic nature," the expert adds."Unlike some other cancers, thyroid cancer does not have a universal population-wide screening programme in India. Screening is largely opportunistic and risk-based," says Dr Nikhil and adds that individuals with a family history of thyroid disorders, previous exposure to radiation therapy in the head or neck region, long-standing thyroid nodules, or certain hormonal imbalances are advised to remain more vigilant. Women, particularly in middle age, often experience thyroid-related changes and should not ignore persistent neck symptoms."Cultural tendencies to normalise discomfort, especially among working women and caregivers who prioritise family health over their own, further compound the delay. Addressing these barriers requires not just medical solutions, but empathetic public communication," he adds. "When thyroid cancer is diagnosed early, treatment outcomes are significantly better. Management usually involves surgery, followed by appropriate medical therapy and long-term monitoring. Early-stage detection often means less extensive surgery, fewer complications, and better quality of life after treatment," he concludes.
