Head & Neck Cancers

Head and neck cancers are a group of malignancies that originate in the oral cavity, throat, larynx, nasal passages, and salivary glands. These cancers can develop in various parts of the head and neck region and can be identified by various names based on their originating location. For instance, when these cancers initiate in the throat, medically known as the pharynx, they can assume distinct designations: nasopharyngeal for the upper throat located behind the nose, oropharyngeal for the middle throat situated behind the mouth, and hypopharyngeal for the lower throat. 

While they share some common characteristics, the causes, symptoms, diagnosis, and treatment can vary depending on the specific location.


  • Tobacco and Alcohol: Smoking and heavy alcohol use are major risk factors for head and neck cancers. The combination of both further increases the risk.
  • Human Papillomavirus (HPV): Certain strains of HPV, notably HPV-16 and HPV-18, are linked to a subset of head and neck cancers, particularly in the oropharynx.
  • Occupational Exposures: Prolonged exposure to specific substances such as asbestos or formaldehyde may elevate the risk.
  • Poor Oral Hygiene: Chronic irritation, inadequate dental hygiene, and persistent inflammation may contribute to cancer development.
  • Diet: A diet low in fruits and vegetables may also be a contributing factor.


  • Lump or Sore: The presence of a painless lump or sore in the mouth, throat, or neck.
  • Persistent Sore Throat: A sore throat that doesn’t resolve.
  • Difficulty Swallowing: Especially if it worsens over time.
  • Hoarseness: A persistent change in the voice.
  • Ear Pain: Unexplained pain in the ear.
  • Bleeding: Unexplained bleeding from the mouth or nose.
  • Nasal Blockage or Persistent Congestion: A blocked or stuffy nose that doesn’t resolve.
  • Swelling: Swelling in the neck or face.
  • Weight Loss: Unexplained and unintended weight loss.
  • Bad Breath: Chronic bad breath (halitosis).


Diagnosing head and neck cancers typically involves the following steps:

  • Medical History and Physical Examination: Discussion of symptoms and risk factors, followed by a comprehensive physical examination.
  • Endoscopy: The use of a thin, flexible tube with a camera to inspect the interior of the throat, larynx, or other areas.
  • Biopsy: Removal of a tissue sample for laboratory analysis to confirm the presence of cancer cells.
  • Imaging Tests: Such as CT scans, MRI, or PET scans to determine the size and extent of the cancer.
  • Dental Examination: To evaluate oral health and address potential sources of irritation.


Treatment options for head and neck cancers depend on the type, location, stage, and overall health of the patient. Common treatment approaches include:

  • Surgery: Removing the tumor and adjacent tissues, which may require reconstructive surgery.
  • Radiation Therapy: Using high-energy rays to target and destroy cancer cells.
  • Chemotherapy: Administering drugs to kill cancer cells or inhibit their growth.
  • Targeted Therapy: Employing drugs that specifically target cancer cells or their growth pathways.
  • Immunotherapy: Enhancing the immune system’s ability to recognize and attack cancer cells.
  • Combination Therapies: Often, a combination of surgery, radiation, and chemotherapy is utilized for more advanced cases.

The treatment plan should be individualized and developed in consultation with a healthcare team experienced in managing head and neck cancers. Early detection and intervention are crucial for the best outcomes in these cancers, and post-treatment care may also be necessary to address functional or cosmetic issues resulting from treatment.
