Throat cancer is a general term for cancers developing in the pharynx (throat) or the larynx (voice box). These malignancies are part of a broader category called head and neck cancers, usually originating in the flat cells lining the throat structures. While you cannot perform a diagnostic test at home, “checking” involves recognizing specific, persistent changes in your body that signal the need for professional medical evaluation, as early detection significantly improves treatment outcomes.
Persistent Symptoms to Look For
The most recognizable signs of throat cancer often mirror symptoms of common, less serious ailments like a cold or allergies, but they differ in their persistence. A change in the voice, such as persistent hoarseness or raspiness that does not improve within two weeks, is a frequent early warning sign, particularly for cancers affecting the vocal cords. This hoarseness results from a tumor interfering with the normal vibration of the vocal folds.
Monitoring for difficulty or pain when swallowing is also an important part of self-vigilance. This symptom can manifest as a sensation that food is catching in the throat or a burning pain upon swallowing liquids or solids. Tumors located in the lower throat, or hypopharynx, can cause this obstruction or discomfort as they grow near the food passage.
A persistent sore throat or cough that does not resolve with typical home remedies or over-the-counter medications should not be ignored. Similarly, an unexplained earache, especially if it is only on one side and continuous, can be a symptom of a throat tumor referring pain through shared nerve pathways.
Routinely check your neck for any new lumps or swelling. Palpating the neck area can reveal enlarged lymph nodes, which may indicate cancer cells have spread from the primary tumor site. Any unexplained weight loss should also raise concern because of the potential difficulty or pain involved in eating.
Factors That Increase Your Vigilance
Certain lifestyle and medical factors significantly increase a person’s underlying risk for developing head and neck cancers, necessitating a higher level of vigilance for the symptoms mentioned above. Tobacco use, including smoking and smokeless products, is one of the most substantial risk factors. Tobacco use is estimated to be responsible for 75% or more of head and neck cancer cases.
Heavy alcohol consumption is another major contributor, and the risk is dramatically compounded when combined with tobacco use. Individuals who both smoke and drink heavily face a risk up to 30 times greater than those who do neither. The combination of these substances creates a synergistic effect that promotes cell damage.
Infection with the Human Papillomavirus (HPV), particularly strain HPV-16, is an increasingly recognized risk factor for oropharyngeal cancers (back of the throat). HPV-related cancers represent a growing portion of diagnoses, often affecting younger individuals who do not have a history of heavy tobacco or alcohol use. This form of cancer is typically spread through intimate contact.
Other factors, though less common, warrant consideration, such as a diet chronically lacking in fruits and vegetables. Chronic gastroesophageal reflux disease (GERD), where stomach acid backs up into the esophagus and throat, can also lead to long-term irritation that may increase risk.
When a Professional Evaluation is Necessary
Self-monitoring is a tool for early awareness, but it does not replace the definitive diagnostic capabilities of a medical professional. If any persistent symptom, such as hoarseness, difficulty swallowing, or a sore throat, lasts for longer than two weeks, a visit to a doctor is warranted.
Your primary care physician will typically begin with a thorough physical examination and a detailed review of your medical history, including questions about the duration of your symptoms and your risk factors. If throat cancer is suspected, a referral to a specialist, such as an otolaryngologist (an ENT doctor), is the next step.
The ENT specialist may perform an in-office procedure called a flexible fiber-optic laryngoscopy, where a thin, lighted tube is passed through the nose to visualize the throat and voice box. If an abnormal area is identified, a tissue sample is necessary, as only a biopsy, examined by a pathologist, can confirm the presence of cancer cells. Imaging tests, such as a CT scan or PET scan, may also be used to determine the extent of the cancer and if it has spread to lymph nodes or other parts of the body.
