Read MoreA stuffy nose or a sinus infection typically clears up with time or treatment. But when sinus symptoms keep coming back or never fully go away, they deserve more than another round of over-the-counter medication.
In rare cases, chronic congestion and other lingering sinus symptoms can be early warning signs of head and neck cancer. Here's what to watch for and when to seek care.
How do I know if my sinus symptoms are something to be concerned about?
Sinus infections are incredibly common, and most are nothing to worry about, but certain patterns are worth discussing with your doctor. Congestion, facial pressure or nasal blockage that has lasted more than 12 weeks without a clear cause meets the definition of chronic and requires a closer evaluation.
“Recurring sinus infections that don't respond to antibiotics are also worth discussing with your doctor,” said Omair Rajput, M.D., a primary care physician with Inspira Health. “Pay attention if your congestion is only on one side of your nose, as this is less characteristic of typical chronic sinusitis and warrants investigation.”
Are there specific warning signs that could point to head and neck cancer?
Yes. Beyond lasting congestion, some symptoms go beyond what you'd expect from a routine sinus infection. These include:
- Unexplained nosebleeds, especially frequent or one-sided ones
- Facial numbness, swelling or pain that doesn't go away
- Vision changes or double vision
- A lump in the neck that persists for more than two to three weeks
- Difficulty opening your mouth or chewing
- Persistent ear pain or one-sided hearing changes
None of these symptoms automatically signals cancer, but each one is a reason to get evaluated rather than wait.
Could head and neck cancer develop without a visible growth?
It can. Some head and neck cancers develop in areas that aren't easy to see, including deep within the sinuses, the back of the nasal cavity and the base of the skull. “Because these tumors are hidden, early symptoms can look a lot like everyday sinus problems,” said Dr. Rajput. “Nasal polyps and other benign growths can mimic the same symptoms, which is exactly why a thorough evaluation matters.”
What does the diagnostic process look like?
If your symptoms raise concern, your primary care physician is the right first call. They can review your history, rule out common causes and refer you to a specialist for further evaluation if needed.
That specialist may perform a nasal endoscopy, an in-office procedure in which a thin flexible scope is gently guided through the nasal cavities to give a clear view of the sinuses and surrounding tissue. It takes only a few minutes and is well tolerated by most people.
Imaging, such as a CT scan or MRI, may also be ordered to get a more complete view. If anything appears unusual, your doctor can take a small tissue sample to confirm or rule out a diagnosis and support early detection.
“Taking sinus symptoms seriously does not mean assuming the worst. It's taking a proactive approach to your health care,” said Dr. Rajput. “If your sinus problems aren't improving, keep coming back or come with any of the warning signs above, don't hesitate to bring them up with your care team sooner rather than later.”
Your primary care physician can review your full symptom history, help make sense of what's going on and connect you with the right next steps.
