What is dysphagia?

Dysphagia means difficulty swallowing — the sensation that food or liquid is sticking, not going down easily, or causing discomfort when swallowed. It is different from the occasional feeling of a lump in the throat during emotional stress (globus sensation), which comes and goes and is not caused by a structural problem.

Dysphagia is one of the most important warning symptoms in cancer medicine because progressive difficulty swallowing is a red flag that should never be ignored or dismissed.

The key warning pattern: progressive dysphagia

The most concerning pattern is progressive difficulty swallowing:

  1. First, solid foods (like roti, rice, or bread) feel like they are sticking or not going down smoothly
  2. Over weeks to months, softer foods also become difficult
  3. Eventually, even liquids are hard to swallow

This progression — solids first, then liquids — strongly suggests a physical narrowing of the oesophagus (food pipe) or throat, and is a hallmark symptom of oesophageal cancer and some head and neck cancers. It should be evaluated by a doctor urgently.

Persistent hoarseness — a separate but equally important red flag

Hoarseness means a rough, raspy, or weak voice that is different from your normal voice. A hoarse voice for a few days with a cold or throat infection is normal. However, hoarseness lasting more than 3 weeks without an obvious cause is a red flag for laryngeal cancer (cancer of the voice box).

Laryngeal cancer is one of the more common head and neck cancers. When it is caught early — at the stage when hoarseness is the only symptom — it has excellent cure rates. Do not wait to see if hoarseness resolves on its own if it has already lasted 3 weeks.

Risk factors — especially important in Bihar

The following risk factors are highly prevalent in Bihar and significantly increase the chance that swallowing problems or hoarseness are related to cancer:

  • Tobacco chewing in any form — gutka, khaini, paan masala with tobacco, zarda. These products keep tobacco and its carcinogens in direct contact with the mouth, throat, and oesophagus for extended periods. They are very widely used in Bihar and are a leading cause of oral, oropharyngeal, and oesophageal cancers in the region
  • Bidi and cigarette smoking — the smoke passes directly over the larynx (voice box) and oesophagus, and is a major risk factor for both laryngeal and oesophageal cancer
  • Alcohol consumption — especially when combined with tobacco, the risk of head and neck cancers multiplies several times
  • Betel nut (supari) chewing — even without tobacco, betel nut is a carcinogen and has been linked to oropharyngeal cancer

If you use any of these products and have noticed swallowing difficulties or a voice change lasting more than 3 weeks, please see a doctor without delay.

Other possible causes of swallowing difficulty

Not every swallowing problem is cancer. Common non-cancerous causes include:

  • GERD (acid reflux) — stomach acid repeatedly burning the lower oesophagus can cause discomfort and, over many years, narrowing (a peptic stricture)
  • Oesophageal spasm — sudden painful tightening of the oesophageal muscle; intermittent, not progressive
  • Achalasia — a condition where the lower oesophageal valve does not relax properly, causing food to back up; typically affects younger adults
  • Pharyngitis or tonsillitis — throat infection can cause temporary difficulty swallowing that resolves with treatment
  • Thyroid enlargement — a large goitre can press on the oesophagus or larynx and cause both swallowing difficulty and voice changes
  • Zenker’s diverticulum — a pouch in the pharynx that collects food; more common in older people

The key distinction is whether the difficulty is progressive (getting worse over time) or intermittent (comes and goes). Progressive dysphagia always needs urgent evaluation.

Hoarseness: other causes

Persistent hoarseness can also be caused by:

  • Vocal cord nodules or polyps — usually from voice overuse; a singer, teacher, or call-centre worker may develop these
  • Laryngopharyngeal reflux — acid from the stomach reaching the voice box, causing irritation
  • Hypothyroidism — an underactive thyroid can cause a husky voice
  • Post-viral nerve weakness — some viral infections can temporarily paralyse a vocal cord

These are treatable non-cancerous causes, but a doctor must examine the vocal cords to distinguish them from laryngeal cancer. This requires a laryngoscopy — a brief examination of the voice box with a small camera or mirror, done by an ENT specialist.

Warning signs that need urgent attention

See a doctor urgently (within days to 1 week) if you have:

  • Any progressive difficulty swallowing — solids becoming harder to swallow, or soft foods and liquids now also difficult
  • Hoarseness that has lasted more than 3 weeks without a cold or obvious infection
  • Difficulty swallowing with unexplained weight loss
  • Difficulty swallowing with pain on swallowing (odynophagia)
  • A visible or palpable lump in the neck alongside swallowing difficulty or hoarseness
  • Coughing or choking when trying to swallow liquids (may suggest the swallowing mechanism is severely affected)

What tests a doctor will recommend

  1. Clinical examination — the doctor will examine the neck for lumps, and an ENT specialist will look at the back of the throat and voice box
  2. Laryngoscopy — the ENT specialist passes a thin flexible camera (nasopharyngoscope) through the nose to look directly at the larynx (voice box) and the back of the throat. This is the essential test for hoarseness and is done as an outpatient procedure
  3. Upper GI endoscopy (OGD scopy — oesophago-gastro-duodenoscopy) — a flexible camera is passed through the mouth into the oesophagus and stomach. This is the gold standard test for swallowing difficulty and can both visualise and biopsy any abnormal area. Available at AIIMS Patna, Mahavir Cancer Sansthan, and several larger hospitals
  4. Barium swallow — a simpler and more widely available test where the patient drinks a barium liquid and X-rays are taken as it passes down the oesophagus. It can show narrowing or irregularities in the oesophagus and is available at district hospitals with an X-ray facility
  5. Biopsy — tissue from any suspicious area seen at endoscopy or laryngoscopy is sent to the laboratory to confirm whether cancer cells are present. This is the only way to diagnose cancer definitively
  6. CT scan of neck and chest — if cancer is confirmed or strongly suspected, a CT scan maps the extent of disease and guides staging

Where to get help in Bihar

  • Mahavir Cancer Sansthan, Phulwarisharif, Patna — head and neck oncology, ENT surgery, upper GI endoscopy, and radiation therapy; the primary cancer referral centre in Bihar
  • AIIMS Patna — ENT and head and neck surgery outpatient departments; laryngoscopy, upper GI endoscopy, CT scan, and oncology services
  • HBCH (Homi Bhabha Cancer Hospital), Muzaffarpur — provides cancer services including head and neck cancer evaluation for patients in north Bihar; reduces the need to travel to Patna
