Head and Neck Cancers: Definition, Causes, Symptoms, and Treatment

Head and Neck Cancers: Definition, Causes, Symptoms, and Treatment

Head and neck tumors are tumoral formations that can occur in the mouth, nose, throat, thyroid gland, and larynx. If not diagnosed early, they can negatively affect both aesthetic appearance and vital functions.

Risk factors include smoking, alcohol consumption, viral infections, and genetic predisposition. Tumors may be benign or malignant, and each requires a different treatment approach.

Endoscopic examination, imaging methods, and biopsy are used for diagnosis. Treatment may involve surgical intervention, radiotherapy, or chemotherapy.

Early diagnosis of head and neck tumors increases treatment success. Regular check-ups and avoiding risk factors play an important role in prevention.

Head and Neck Cancers: What They Are, Causes, Symptoms, and Treatment

Head and neck tumors are very common cancers. They account for 9% of all cancers and 4% of cancer-related deaths. These types of cancer, which most commonly occur in the thyroid, lips, oral cavity, tongue, cheek, base of the tongue, larynx, nasopharynx, pharynx, salivary glands, nose, and paranasal sinuses, are considered one of the most significant health problems worldwide, with approximately 55,000 new cases reported each year.
According to studies, more than 10,000 cases of laryngeal and oral cancer are reported every year. Most originate from squamous epithelial cells. In advanced-stage tumors, cancer cells may spread to the lymph nodes in the neck or to distant organs (lungs, bones, liver).

What Are the Symptoms of Head and Neck Tumors (Cancer)?

Head and neck tumors may cause various symptoms depending on the site from which they originate.

  • Swelling in the head and neck
  • Non-healing sores on the lips, tongue, or inside the mouth
  • Hoarseness
  • Difficulty swallowing
  • Nasal congestion
  • Ear pain
  • Hearing loss
  • Facial paralysis

How Are Head and Neck Tumors (Cancer) Diagnosed and Treated?

Head and neck tumor diagnosis involves comprehensive medical history taking, detailed physical examination, biopsy, computed tomography and/or MRI, and methods such as PET-CT.

Treatment may be performed with surgery and/or radiotherapy. Factors such as the location of the tumor, cell type, stage, and the preferences of the patient and surgeon determine the treatment to be applied. One of the important points is that during surgery, it may sometimes be necessary to remove the lymph nodes in the neck along with the organ from which the tumor originated (neck dissection). In some cases, adjuvant radiotherapy and/or chemotherapy may be required after surgery.
