Throat : Larynx, Hypopharynx Cancer
Signs and Symptoms of Throat Cancer
- Pharynx – The pharynx is a hollow tube about 5 inches long that starts behind the nose and leads to the esophagus (food pipe ) and the trachea (wind pipe). The pharynx has three parts
- Nasopharynx – The nasopharynx, the upper part of the pharynx, is behind the nose.
- Oropharynx – The oropharynx is the middle part of the pharynx. The oropharynx includes the soft palate (the back of the mouth), the base of the tongue, and the tonsils.
- Hypopharynx – The hypopharynx is the lower part of the pharynx.
- Larynx – The larynx, also called the voice box, is a short passageway formed by cartilage just below the pharynx in the neck. The larynx contains the vocal cords. It also has a small piece of tissue, called the epiglottis, which moves to cover the larynx to prevent food from entering the air passages.
Most Common Symptoms
- Hoarseness of voice
- Swelling or lump in the neck
- Ear pain
- Difficulty in swallowing (more to solid food)
- Difficulty in breathing
- Persistent cough
Types of Cancer
Cancer of throat means involvement of hollow tube from behind nose to top of windpipe. It means nasopharynx, oropharynx, hypopharynx and larynx(voice box )
Causes and Risk Factors of Throat Cancer
Smoking-most important
Alcoholism
Viral infections—HPV,EBV
Iron/ nutritional deficiency
Reflux oesophagitis
Screening and Diagnosis
Heavy smoker should have regular check ups. Be aware of early warning signals of head and neck cancers.If symptoms don’t subside in 3 week’s time , report to the doctor for clinical examination and further investigations.
How Do We Diagnose?
To find the cause of symptoms, a surgical oncologist evaluates a person’s medical history, performs a physical examination, and orders diagnostic tests. The examination and tests conducted may vary depending on the symptoms. Direct Laryngoscopy is done to view the larynx and take a biopsy;
- Laboratory tests examine samples of blood, urine, or cells from the nodes.
- CT scan /Magnetic resonance imaging (or MRI) of head and neck.
- PET scan in selected advanced cases..

Clinical Trials of Throat Cancer
Tumor Board/ Multispecialty Clinic Evaluation
Each and every Head & Neck cancer patient is evaluated by a special team of Surgical Oncologists (Head & Neck unit), Medical Oncologists, Radiation Oncologists, Onco-pathologists and Imaging Specialists. Depending on the age, general condition, type of pathology and stage of the disease, a custom made treatment plan is charted out for each and every patient as per International Treatment Guidelines. (NCCN – National Comprehensive Cancer Network)
When to Reach the Treating Team?
- As per appointment.
- If the swelling around the neck wound increases suddenly or within few hours.
- Fresh bleeding from neck wound or oral cavity or stoma. Minimal blood-stained discharge during coughing is acceptable.
- If there’s difficulty in breathing or swallowing, fever.
- If symptoms of hypocalcemia appear (tingling, numbness, or twitching sensation around lips, finger tips, and toe tips. Spasm of hands and feet). Immediately have 4 tablets of calcium. The required injection of Calcium Gluconate is written in your discharge summary. You can receive the same at any nearest health care institution.
