Currently, the average 5-year survival rate for esophageal cancer is roughly 20%, primarily because it often progresses silently and goes undetected. However, when caught early, the survival rate is significantly higher; early detection saves lives and is crucial for effective treatment.
As we observe Esophageal Cancer Awareness Month this April, Beacon Clinic in North Idaho wants to stress how important it is for all of us to understand the risk factors, early symptoms, and early screening options for esophageal cancer. With vigilance and intention, we can improve outcomes for those who have esophageal cancer.
Understanding Esophageal Cancer
As its name denotes, esophageal cancer originates in the esophagus, the long tube through which food travels from the throat to the stomach. Worldwide, this type of cancer is the eighth most common and the sixth leading cause of cancer-related deaths. The disease is particularly aggressive, often diagnosed at advanced stages when survival is less likely. Consequently, the best outcomes can only be achieved by paying close attention to its risks and symptoms and pursuing early diagnosis and care.
Risk Factors
Several factors increase the likelihood of developing esophageal cancer. Although these factors may not demonstrate direct causal connections, those with these risk factors should be more vigilant:
- Age and Gender: Individuals over 55 are at higher risk, and men are three times more susceptible than women.
- Tobacco and Alcohol Use: Smoking and heavy alcohol consumption significantly elevate the risk.
- Gastroesophageal Reflux Disease (GERD): Chronic acid reflux can damage the esophageal lining, leading to Barrett’s esophagus, a precancerous condition.
- Obesity: Excess body weight, particularly abdominal fat, increases the risk of esophageal adenocarcinoma.
- Diet and Nutrition: A diet with insufficient fruits and vegetables or too much processed foods and meats may contribute to a higher risk.
- Other Medical Conditions: Achalasia (a condition where the esophagus has trouble moving food into the stomach) and previous radiation treatment to the chest or upper abdomen can also increase the risk.
Symptoms
Early-stage esophageal cancer often presents no symptoms, but as the disease progresses, individuals may experience:
- Difficulty Swallowing (Dysphagia): The sensation that food is stuck in the chest or throat
- Unexplained Weight Loss: Significant weight loss without changes in diet or exercise.
- Chest Pain or Discomfort: Persistent pain, pressure, or burning in the chest
- Chronic Cough or Hoarseness: A lingering cough or voice changes
- Indigestion or Heartburn: Persistent digestive discomfort not relieved by standard treatments
These symptoms are present in various health conditions, but if they persist, it is vital to consult a physician for evaluation.
Early Screening Options
When esophageal cancer is detected early, treatment outcomes are significantly improved. Screening is essential for individuals with risk factors such as Barrett’s esophagus, chronic GERD, or a family history of esophageal cancer. Current screening methods include:
- Upper Endoscopy (Esophagogastroduodenoscopy or EGD): Exploration using a flexible tube equipped with a camera and inserted into the esophagus to visually examine it, helping physicians perform a biopsy of suspicious areas
- Biopsy: Removal of a small tissue sample during endoscopy to check for cancerous cells
- Brush Cytology: Collecting cells from the esophagus lining using a brush during endoscopy for microscopic examination.
Emerging technologies are being studied for their potential to detect precancerous conditions like Barrett’s esophagus less invasively. For example, the “sponge on a string” test involves swallowing a small capsule attached to a string. The capsule then expands into a sponge to collect cells from the esophagus lining for analysis.
