Head and Neck Cancer: Symptoms, Causes and Management
Head and neck cancer encompasses a range of cancers that develop in the mouth, throat, nose, sinuses, and other areas of the head and neck. Understanding the risk factors associated with these types of cancers is essential for early diagnosis and effective treatment.
What Are Head and Neck Cancers?
Head and neck cancers are a group of cancers that typically begin in the squamous cells that line the moist surfaces inside the head and neck. These cancers can affect various regions, including the oral cavity, pharynx, larynx, nasal cavity, and salivary glands. Early detection and diagnosis are crucial for improving outcomes and survival rates.

Types of head and neck cancer:
- Oral cancer
- Oropharyngeal cancer
- Hypopharyngeal cancer
- Laryngeal cancer
- Nasopharyngeal cancer
- Salivary gland cancer
- Nasal cavity and paranasal sinus cancer
Cancers of the head and neck can spread to the lymph nodes in the upper part of the neck.
Symptoms of Head and Neck Cancer
Recognizing the symptoms of head and neck cancer early can lead to a timely diagnosis and better treatment outcomes. Common symptoms include:
- A lump or sore that does not heal
- Persistent sore throat
- Difficulty swallowing
- Changes in voice or hoarseness
- Unexplained weight loss
- Ear pain
- Persistent nasal congestion or nosebleeds
If you experience any of these symptoms for an extended period, it is essential to consult a healthcare professional for further evaluation.
Risk Factors of Head and Neck Cancer
Head and neck cancers mainly affect men and people over 50. Key risk factors include smoking, heavy alcohol use, and HPV infections. Risk factors may vary by cancer type.
- Using tobacco: The most common cause of head and neck cancer is tobacco use, which is linked to about 70% to 80% of these cases. Smoking (cigarettes, cigars, pipes) and using smokeless tobacco (chewing tobacco, snuff, dip) all increase the risk. Exposure to secondhand smoke may also raise the risk.
- Drinking too much alcohol: Excessive alcohol consumption can raise the risk. If you drink, it is recommended not to have more than two drinks per day for men and individuals with AMAB and one drink per day for women and people with AFAB.
- Human papillomavirus (HPV): The rate of head and neck cancers linked to HPV infection is rising, especially in young individuals. HPV infection is linked to up to 75% of oropharyngeal cancers.
- Epstein-Barr virus (EBV): EBV is most usually connected with mono. However, it is also associated with cancer risk. According to research, EBV infection can cause nasopharyngeal cancer.
- Having a weak immune system: A weaker immune system makes the body's battle against cancer more difficult. HIV infection and recent major surgeries (like organ or bone marrow transplants) have been associated with cancer resulting from weakened immune systems.
- Radiation exposure:Radiation therapy for tumors, whether malignant or benign, has a slight risk of causing salivary gland cancer. However, the overall risk is low.
- Diet: Consuming excessive amounts of salt-cured foods, such as salt-cured meat and fish, can elevate the chances of developing nasopharyngeal cancer.
- Genetic factors: Inherited genetic variations, such as those in individuals with Fanconi anemia, can increase the risk of certain cancers. Tobacco use can further elevate this risk in those with genetic predispositions.
- Poor dental hygiene: Neglecting adequate dental care, such as brushing, flossing, and dental checkups, might increase the risk of diseases and oral cancer.
Head and Neck Cancer Diagnosis
Diagnosing head and neck cancer typically involves a combination of physical examinations, imaging tests, and biopsies.
Physical Examination
A thorough physical examination by a healthcare professional can help identify any abnormal growths or lesions in the head and neck region. This examination may include a visual inspection and palpation of the affected areas.
Imaging Tests
Imaging tests, such as CT scans, MRI scans, and PET scans, are used to obtain detailed images of the head and neck. These tests can help determine the extent of the cancer and whether it has spread to other areas.
Biopsy
A biopsy involves removing a small sample of tissue from the suspected cancerous area and examining it under a microscope. This procedure is crucial for confirming the presence of cancer and determining its type and stage.
Head and Neck Tumor Management
Once head and neck cancer is diagnosed, a comprehensive treatment plan is developed based on the type, location, and stage of the cancer. Treatment options may include surgery, radiation therapy, chemotherapy, targeted therapy, and immunotherapy.
- Surgery : Surgery is often the first line of treatment for head and neck cancers. The goal of surgery is to remove the tumor and any affected surrounding tissue. In some cases, reconstructive surgery may be necessary to restore function and appearance.
- Radiation Therapy : Radiation therapy uses high-energy beams to destroy cancer cells. It is commonly used in conjunction with surgery or as a standalone treatment for smaller, localized tumors. Radiation therapy can also help relieve symptoms and improve quality of life.
- Chemotherapy :Chemotherapy involves the use of powerful drugs to kill cancer cells. It is often used in combination with radiation therapy or surgery to enhance the effectiveness of treatment. Chemotherapy may also be used to treat advanced or metastatic head and neck cancers.
- Targeted Therapy : Targeted therapy focuses on specific molecules or pathways that contribute to cancer growth. These therapies can block the action of these molecules, slowing or stopping the growth of cancer cells. Targeted therapy is often used in cases where traditional treatments are ineffective.
- Immunotherapy : Immunotherapy works by stimulating the body's immune system to recognize and attack cancer cells. This treatment option has shown promise in treating certain types of head and neck cancers, particularly those associated with HPV.
