What is Esophageal Cancer?

What is Esophageal Cancer?

Esophageal cancer is a disease in which abnormal cells grow in the esophagus (food pipe). The esophagus is the tube that carries food and liquids from the mouth to the stomach.

The two main types are:

• Squamous cell carcinoma
• Adenocarcinoma

Why is this condition important?

Esophageal cancer can affect swallowing, nutrition, and overall health. If not diagnosed early, the cancer may grow deeper into the food pipe or spread to other parts of the body.

Early diagnosis and treatment can cure the disease.

Who is commonly affected?

Esophageal cancer is more common in:

• Adults over 50 years
• Men
• Smokers
• People who consume alcohol heavily
• Individuals with long-term acid reflux
• People with obesity

According to the World Health Organization (WHO), esophageal cancer is among the common cancers globally and remains a major cause of cancer-related deaths in many countries.It is the 5 most common cancers in India with around 5% of the population affected by it.

Why it Happens

Esophageal cancer develops due to long-term damage to the cells lining the food pipe.

Common risk factors include:

• Tobacco use
• Heavy alcohol consumption
• Long-standing acid reflux (GERD)
• Barrett’s esophagus
• Obesity
• Increasing age

Signs and Symptoms

Symptoms often develop gradually and may become more noticeable over time.

Common symptoms

• Difficulty swallowing
• Unintentional weight loss
• Chest discomfort or pain
• Heartburn or acid reflux
• Hoarseness

Warning signs needing medical attention

• Progressive difficulty swallowing
• Vomiting blood
• Black stools
• Severe weight loss
• Persistent chest pain

These symptoms should not be ignored, especially if they continue for several weeks.

Diagnosis and Investigations

Doctors use several tests to diagnose esophageal cancer and determine its stage.

Common tests

• Endoscopy: A thin flexible tube with a camera is passed through the mouth to examine the food pipe.
• Biopsy: A small tissue sample is taken during endoscopy and checked under a microscope to confirm cancer.
• CT Scan: Helps determine whether cancer has spread to nearby organs or lymph nodes.
• PET Scan: May help detect cancer spread in other parts of the body.
• Endoscopic Ultrasound (EUS): Uses ultrasound during endoscopy to assess tumor depth and nearby lymph nodes.

What patients should expect

Most tests are performed as outpatient procedures. Sedation may be used during endoscopy to improve comfort.

The results help doctors plan the best treatment approach.

Treatment Options

Treatment depends on cancer stage, tumor location and overall patient health.

• Surgery: Surgery may involve removing part or most of the affected esophagus. This procedure is called esophagectomy. The stomach may be reshaped to help swallowing after surgery.
• Chemotherapy: Uses medicines to kill cancer cells and may be given before surgery, after surgery or along with radiation therapy.
• Radiation Therapy: Uses high-energy rays to destroy cancer cells and shrink tumors.
• Targeted Therapy and Immunotherapy: Some patients may benefit from advanced medicines that target cancer cells or help the immune system fight cancer.
• Supportive Care: Treatment may also focus on improving swallowing, pain control and nutritional support

Living with Esophageal Cancer

Nutrition and Eating Support

Patients may need:

• Soft or semi-solid foods
• Small frequent meals
• High-protein nutritional support
• Dietitian guidance

Maintaining nutrition is very important during treatment.

Emotional and Mental Health

Cancer diagnosis and treatment can cause stress and anxiety. Emotional support and counseling may help patients and families cope better.

Long-term Follow-up

Regular follow-up visits help:

• Monitor recovery
• Detect recurrence early
• Manage treatment side effects
