Oesophageal cancer is a serious condition affecting the oesophagus, the long, hollow tube connecting the throat to the stomach. It plays a crucial role in transporting food to the stomach for digestion. Unfortunately, oesophageal cancer often develops silently, with early symptoms that are easy to overlook. Recognising the symptoms and causes of oesophageal cancer is essential for timely diagnosis and effective treatment. Early detection significantly improves recovery outcomes and enhances quality of life.
At Venkateshwar Hospitals, a leading centre for cancer care, patients receive advanced diagnostic support and specialised treatment guided by experienced oncologists and multidisciplinary teams.
What Is Oesophageal Cancer?
Oesophageal cancer is a condition in which malignant (cancerous) cells develop in the tissues of the oesophagus, the muscular tube that links the throat to the stomach. The two main types are adenocarcinoma, which arises in glandular cells formed in the lower oesophagus (often due to Barrett’s oesophagus), and squamous cell carcinoma, which originates in the flat cells lining the oesophagus.
1. Basic Anatomy of the Oesophagus
The oesophagus is a muscular tube approximately 25 cm long that transports food and liquids from the mouth to the stomach. Its inner lining consists of squamous cells, which can become cancerous under certain conditions. Adenocarcinoma develops from glandular cells formed in Barrett’s oesophagus, not from normal oesophageal lining.
Types of Oesophageal Cancer
Oesophageal cancer can develop in different cell types, and identifying the specific type is crucial for accurate diagnosis and effective treatment. The two most common forms are squamous cell carcinoma and adenocarcinoma, each with distinct causes, locations, and risk factors.
1. Squamous Cell Carcinoma
Originates in the thin, flat cells lining the upper and middle parts of the oesophagus. Strongly associated with tobacco and alcohol use.
2. Adenocarcinoma
Develops in the lower part of the oesophagus due to metaplastic glandular cells in Barrett’s oesophagus, often linked to chronic acid reflux (GERD). Alcohol is less clearly implicated.
Understanding these types helps doctors design precise treatment plans tailored to the patient’s condition.
Oesophageal Cancer Symptoms
The symptoms of oesophageal cancer vary depending on the stage of the disease. Early signs are often subtle and may resemble digestive problems, leading to delayed diagnosis.
Early Symptoms
- Difficulty Swallowing (Dysphagia): Trouble swallowing solid food initially, progressing to liquids.
- Persistent Reflux or Heartburn: Often associated with Barrett’s oesophagus and may signal early changes in the lower oesophagus.
Note: Unexplained weight loss and chest discomfort are less typical as early symptoms, particularly in adenocarcinoma.
Advanced Symptoms
- Hoarseness or chronic cough: Caused by tumour irritation or nerve involvement.
- Vomiting or regurgitation: Food or liquids coming back up due to obstruction.
- Pain in throat, chest, or back: Worsening discomfort as cancer spreads.
- Bleeding or anaemia: Internal bleeding leading to fatigue or weakness.
Medical Note: Persistent difficulty swallowing should prompt immediate medical attention. Early detection offers the best chance of successful treatment.
Causes of Oesophageal Cancer
Oesophageal cancer arises primarily due to lifestyle and medical factors, while genetics and environmental exposures play a more modest role.
Lifestyle and Environmental Factors
- Tobacco use: Smoking and chewing tobacco significantly increase the risk.
- Excessive alcohol consumption: Strongly linked to squamous cell carcinoma; evidence for adenocarcinoma is less clear.
- Poor diet: A diet low in fruits, vegetables, and whole grains may contribute to risk.
Medical Conditions That Increase Risk
- Gastroesophageal reflux disease (GERD): Chronic acid reflux damages the oesophagus and increases adenocarcinoma risk.
- Barrett’s oesophagus: A precancerous condition where the oesophageal lining changes due to long-term GERD.
- Obesity: Excess body fat can worsen acid reflux and oesophageal inflammation.
Genetic and Other Factors
- Family history: Modestly increases risk; no specific genetic mutations are well established as major causes.
- Age and gender: More common in men over 50 years of age.
Note: Environmental chemical or radiation exposure is a minor, rare risk factor.
When to See a Doctor?
Early diagnosis makes a significant difference in managing oesophageal cancer effectively. Individuals should seek medical advice if they experience persistent swallowing difficulties or symptoms of advanced disease.
At Venkateshwar Hospitals, patients benefit from:
- Advanced diagnostic facilities including endoscopy, biopsy, CT/MRI scans, and PET imaging.
- Expert consultations with oncologists and gastroenterologists for accurate evaluation.
- Comprehensive treatment planning tailored to each patient’s stage and condition.
Timely evaluation also identifies precancerous changes like Barrett’s oesophagus, enabling preventive intervention.
