Expert Care for Head and Neck Cancer

Head and Neck Cancer: Symptoms, Causes, Diagnosis, and Treatment | AIROC Hospitals

About Head and Neck Cancer – Overview and Types

Head and neck cancer refers to a group of cancers that begin in the tissues and organs of the head and neck region, including the mouth, throat, voice box, sinuses, nasal cavity, and salivary glands. These cancers most commonly begin in the squamous cells that line the moist surfaces inside the head and neck. At AIROC Hospitals, our head and neck oncology specialists provide comprehensive, organ-preserving care aimed at treating the cancer effectively while protecting speech, swallowing, and appearance wherever possible.

Because the head and neck region contains many vital structures involved in breathing, eating, and speaking, early diagnosis and a coordinated treatment approach are especially important for preserving quality of life.

Types of Head and Neck Cancer

Head and neck cancer is classified based on the specific site where it originates:

• Oral Cavity Cancer – Affects the lips, tongue, gums, inner cheek lining, and the floor or roof of the mouth.
• Oropharyngeal Cancer – Develops in the middle part of the throat, including the tonsils and base of the tongue, and is increasingly linked to HPV infection.
• Laryngeal Cancer – Affects the voice box (larynx), which is involved in speech and breathing.
• Nasopharyngeal Cancer – Originates in the upper part of the throat behind the nose.
• Hypopharyngeal Cancer – Develops in the lower part of the throat, just above the esophagus and windpipe.
• Salivary Gland Cancer – A less common type arising in the glands that produce saliva.
• Nasal Cavity and Paranasal Sinus Cancer – Develops within the nasal passages or the sinuses surrounding the nose.

Because treatment and prognosis vary significantly by site, our specialists at AIROC Hospitals conduct a thorough, site-specific evaluation to guide the most effective care.

 

Symptoms and Causes

Common Symptoms of Head and Neck Cancer

Symptoms depend on the specific site involved but often include:

• A persistent sore or ulcer in the mouth that doesn't heal
• A lump or swelling in the neck, mouth, or throat
• Persistent sore throat or hoarseness
• Difficulty or pain when swallowing
• Unexplained weight loss
• Persistent nasal congestion or nosebleeds
• Numbness or pain in the face, mouth, or neck
• Changes in voice or speech
• Ear pain without an obvious ear infection
• White or red patches inside the mouth

Because early symptoms can be mistaken for common infections or irritations, any persistent symptom lasting more than a few weeks should be evaluated by a specialist.

Causes and Risk Factors

Head and neck cancers are strongly linked to specific lifestyle and infectious risk factors:

• Tobacco Use: One of the leading risk factors across nearly all head and neck cancer types, including smoking and smokeless tobacco.
• Alcohol Consumption: Heavy alcohol use significantly increases risk, especially when combined with tobacco use.
• Human Papillomavirus (HPV) Infection: A growing cause of oropharyngeal cancer, particularly among younger, non-smoking individuals.
• Epstein-Barr Virus (EBV): Associated with an increased risk of nasopharyngeal cancer.
• Poor Oral Hygiene: Chronic irritation from ill-fitting dentures or poor dental care may contribute to oral cavity cancer risk.
• Occupational Exposures: Prolonged exposure to wood dust, asbestos, or certain chemicals is linked to nasal and sinus cancers.
• Betel Nut Chewing: A well-established risk factor for oral cancer in regions where this practice is common.
• Age and Sex: More common in individuals over 50 and occurs more frequently in men than women.

Understanding these risk factors helps our specialists at AIROC Hospitals guide patients toward appropriate screening and preventive strategies.

 

Diagnosis and Treatment

How Head and Neck Cancer Is Diagnosed

At AIROC Hospitals, we use a combination of physical examination, imaging, and laboratory techniques to accurately diagnose head and neck cancer:

• Physical and Endoscopic Examination: A thorough examination of the mouth, throat, and neck, often using a thin, flexible scope to view areas not visible externally.
• Biopsy: A tissue sample is taken from the suspicious area and examined under a microscope to confirm the diagnosis.
• Imaging Tests: CT, MRI, and PET scans help determine tumor size, location, and whether the cancer has spread to nearby lymph nodes or other areas.
• HPV and EBV Testing: Performed on tumor tissue to help guide treatment planning, particularly for oropharyngeal and nasopharyngeal cancers.
• Fine-Needle Aspiration: Used to sample a lump in the neck to check for cancerous cells.
• Dental and Nutritional Evaluation: An important part of pre-treatment planning, given the close involvement of the mouth and throat.

Treatment Options at AIROC Hospitals

Treatment for head and neck cancer is tailored to the tumor site, stage, and the patient's overall health, and may include:

• Surgery: Aimed at removing the tumor while preserving as much function and appearance as possible, sometimes involving reconstructive techniques.
• Radiation Therapy: A central treatment for many head and neck cancers, often used alone for early-stage disease or combined with other therapies for more advanced cases.
• Chemotherapy: Frequently combined with radiation (chemoradiation) to improve treatment effectiveness, particularly in locally advanced cancers.
• Targeted Therapy: Treatments directed at specific molecular features of the tumor, used in certain advanced or recurrent cases.
• Immunotherapy: An option for advanced or recurrent head and neck cancers that do not respond to standard treatment.
• Speech and Swallowing Rehabilitation: Given the impact on essential functions, our team provides dedicated support to help patients recover speech and swallowing ability after treatment.

Our multidisciplinary team at AIROC Hospitals — including head and neck surgeons, radiation oncologists, dental specialists, and speech-language therapists — works together to deliver coordinated care focused on both survival and quality of life.

 

Prevention and Risk Factors

While not all head and neck cancers can be prevented, several steps can meaningfully reduce risk and support early detection:

• Avoiding Tobacco in All Forms: One of the most effective ways to lower risk, including smoking and smokeless tobacco products.
• Limiting Alcohol Consumption: Reducing alcohol intake, especially in combination with tobacco use, lowers risk significantly.
• HPV Vaccination: Helps protect against HPV-related oropharyngeal cancer when given at the recommended age.
• Maintaining Good Oral Hygiene: Regular dental care and check-ups can help detect early changes in the mouth.
• Protecting Against Occupational Exposures: Using appropriate protective equipment when working with wood dust, chemicals, or other known irritants.
• Prompt Evaluation of Persistent Symptoms: Any mouth sore, lump, or voice change lasting more than two to three weeks should be evaluated by a specialist without delay.

At AIROC Hospitals, we encourage regular dental and medical check-ups along with prompt attention to persistent symptoms, as early detection plays a vital role in successfully treating head and neck cancer while preserving essential functions.
