Head and Neck Cancer

What Is Head and Neck Cancer? Signs, Symptoms, and When to See a Specialist

At Cancer Care Northwest, Head and Neck Cancer Awareness Month is an opportunity to help patients and families better understand the early signs of disease and the importance of timely evaluation. Head and neck cancer refers to a group of cancers that begin in the mouth, throat, voice box, sinuses, or salivary glands. While these cancers account for a smaller percentage of overall cancer diagnoses, early detection plays a critical role in improving outcomes. Understanding the signs and symptoms—and knowing when to seek care—can make a meaningful difference.

What Is Head and Neck Cancer?

Head and neck cancers typically start in the squamous cells that line the moist surfaces inside the head and neck. These cancers are often categorized based on where they begin, including:

• Oral cavity (mouth, lips, gums, tongue)
• Pharynx (throat)
• Larynx (voice box)
• Nasal cavity and sinuses
• Salivary glands

One of the fastest-growing causes of head and neck cancer is human papillomavirus (HPV), particularly in cancers of the throat (oropharynx). Traditional risk factors like tobacco and alcohol use also remain significant.

 

Common Signs and Symptoms of Head and Neck Cancer

Early symptoms can be subtle and are often mistaken for less serious conditions. If any of the following symptoms persist for more than two weeks, it’s important to seek medical evaluation:

Persistent Symptoms to Watch For

• A sore throat that doesn’t go away
• Difficulty swallowing or a feeling that something is stuck in the throat
• Hoarseness or voice changes
• A lump in the neck or throat
• Unexplained weight loss
• Ear pain without infection
• Chronic sinus infections or nasal congestion

Oral Symptoms

• White or red patches in the mouth
• Pain or swelling in the jaw
• Loose teeth without dental cause
• Non-healing sores or bleeding in the mouth

Advanced Symptoms

• Trouble breathing
• Difficulty opening the mouth
• Numbness or weakness in the face
• Persistent bad breath

These symptoms don’t always mean cancer—but they should never be ignored if they persist.

 

Risk Factors for Head and Neck Cancer

Understanding your risk can help guide prevention and early detection:

• Tobacco use (including smoking and chewing tobacco)
• Heavy alcohol consumption
• HPV infection
• Prolonged sun exposure (linked to lip cancer)
• Poor oral hygiene
• Exposure to certain workplace chemicals

People with multiple risk factors should be especially vigilant about symptoms.

 

When to See a Specialist

Early diagnosis is one of the most important factors in successful treatment. You should consider seeing a specialist—such as an ear, nose, and throat (ENT) physician or an oncologist—if:

• Symptoms last longer than two weeks
• A lump in the neck does not go away or continues to grow
• You experience ongoing difficulty swallowing or speaking
• Pain persists without a clear cause
• You have a history of tobacco or alcohol use and notice new symptoms

Primary care providers and dentists are often the first to detect early warning signs and can refer you to a specialist for further evaluation.

 

How Head and Neck Cancer Is Diagnosed

If cancer is suspected, your care team may recommend:

• A physical exam of the head and neck
• Imaging tests such as CT, MRI, or PET scans
• Endoscopy to examine internal structures
• Biopsy to confirm diagnosis

Early-stage cancers are often more treatable and may require less intensive therapy.

 

Why Early Detection Matters

Cancers found at an early stage are generally easier to treat and associated with better outcomes. In many cases, early detection can also preserve important functions like speaking, swallowing, and breathing.

Raising awareness of head and neck cancer symptoms empowers individuals to seek care sooner—when it matters most.
