Esophageal Cancer


Esophageal cancer refers to the development of malignant (cancerous) cells in the tissues lining the esophagus. The esophagus is a muscular tube that connects the throat to the stomach, and its primary function is to transport food and liquids from the mouth to the stomach. The esophagus is a long, hollow tube that connects your throat to your stomach. Esophageal cancer is a type of cancer that develops there. The food you swallow is moved through your esophagus from the back of your throat to your stomach so it may be digested.

Usually, the cells that line the inside of the esophagus are where esophageal cancer develops. Anywhere along the esophagus is susceptible to esophageal cancer. Esophageal cancer affects more males than women.

The sixth most frequent cause of cancer-related fatalities globally is esophageal cancer. varying geographic regions have varying incidence rates. The use of alcohol and tobacco products, as well as certain dietary practices and obesity, may all contribute to the greater prevalence of esophageal cancer in specific areas.

Signs and Symptoms:-

Symptoms of esophageal cancer may include difficulty swallowing (dysphagia), unintentional weight loss, chest pain or discomfort, chronic cough, hoarseness, or vomiting. However, in the early stages, esophageal cancer may not cause noticeable symptoms, which can lead to a late-stage diagnosis.

  • Difficulty swallowing (dysphagia)
  • Weight loss without trying
  • Chest pain, pressure, or burning
  • Worsening indigestion or heartburn
  • Coughing or hoarseness
  • Early esophageal cancer typically causes no signs or symptoms.

If you have any persistent symptoms that bother you, schedule a visit with your doctor.

Your chance of developing esophageal cancer is increased if you have Barrett's esophagus, a precancerous disease brought on by persistent acid reflux. Consult your doctor for a list of symptoms and indications that might indicate a worsening of your disease.

Barrett's esophagus sufferers may choose to undergo esophageal cancer screening. Talk to your doctor about the benefits and drawbacks of screening if you have Barrett's esophagus.


The specific causation of esophageal cancer is unclear.

Esophageal cells can become cancerous when changes (mutations) arise in their DNA. Cells expand and divide out of control as a result of the alterations. The esophagus develops a tumor from the accumulating aberrant cells, which has the potential to spread to other organs and adjacent tissues. The exact cause of esophageal cancer is not fully understood, but certain risk factors increase the likelihood of developing the disease. These risk factors include:

  • Tobacco and alcohol use: Long-term tobacco use, particularly smoking, and heavy alcohol consumption significantly increase the risk of esophageal cancer.
  • Gastroesophageal reflux disease (GERD): Chronic acid reflux, where stomach acid backs up into the esophagus, can cause inflammation and cellular changes that may lead to cancer over time.
  • Barrett's esophagus: Chronic gastroesophageal reflux disease can lead to Barrett's esophagus, a condition in which the cells in the lower esophagus change, increasing the risk of esophageal cancer.
  • Obesity: Being overweight or obese increases the risk of developing adenocarcinoma of the esophagus.
  • Age and gender: Esophageal cancer is more common in older adults and is more frequently diagnosed in men than women.

There are two main types of esophageal cancer:

Adenocarcinoma: This type of esophageal cancer usually begins in the glandular cells that produce mucus in the lower part of the esophagus. It is often associated with a condition called Barrett's esophagus, which is a precancerous change in the cells lining the esophagus.

Squamous cell carcinoma: This type of esophageal cancer develops in the thin, flat cells lining the upper part of the esophagus. It is commonly associated with risk factors such as smoking, excessive alcohol consumption, and a history of acid reflux or chronic irritation of the esophagus.

The diagnosis of esophageal cancer involves a combination of medical history evaluation, physical examination, imaging tests (such as endoscopy, barium swallow, and CT scan), and biopsy (tissue sample analysis).


Treatment options for esophageal cancer depend on the stage of the disease and may include:

  • Surgery: Surgical removal of the cancerous portion of the esophagus may be performed, along with nearby lymph nodes. In some cases, the remaining healthy portion of the esophagus is reattached to the stomach.
  • Radiation therapy: High-energy radiation is used to kill cancer cells or shrink tumors before surgery or as a primary treatment option for patients who are not surgical candidates.
  • Chemotherapy: Anti-cancer drugs are used to kill cancer cells or slow down their growth. Chemotherapy can be used before surgery (neoadjuvant), after surgery (adjuvant), or as the main treatment for advanced-stage esophageal cancer.
  • Targeted therapy and immunotherapy: These newer treatment approaches focus on specific molecular targets in cancer cells or enhance the body's immune system to fight cancer
  • Endoscopic submucosal dissection (ESD): Surgeons can utilize ESD to treat esophageal cancer which is still in its very early stages.
  • Endoscopic mucosal resection (EMR):- A surgical technique used to remove malignancies from the esophageal mucosa.
  • Endoscopic laser therapy: When tumors may obstruct your esophagus, making it difficult for you to swallow, this treatment helps to relieve symptoms.

The tenth most prevalent cancer in the world is esophageal cancer. One of the hardest malignancies to cure is this one. Because of the symptoms it creates, people might not become aware of them until the disease has already spread. For esophageal cancer, there is frequently no treatment. In that case, healthcare professionals focus on providing patients with the finest care possible so that they can live as long as possible. Being informed that you are ill and there is no treatment is one of life's most challenging experiences. You might need some time and support to accept your circumstances. Healthcare professionals are aware of this and will take all reasonable steps to assist you, including suggesting that you talk with a mental health professional.
