# Esophageal cancer
What is it
Esophageal cancer is a malignant tumor in the esophagus (also called the esophagus), the tube that transports food and drink from your mouth to your stomach. There are two main types: **squamous cell carcinoma** (arises from the innermost layer of the esophagus) and **adenocarcinoma** (arises from glands in the esophageal wall). These two types have different causes and characteristics.
Esophageal cancer is relatively rare in the Netherlands, but worldwide one of the more common types of cancer. It is usually only detected at an advanced stage, because symptoms in the early phase are often absent or go unnoticed.
Causes
For **squamous cell carcinoma** the main risk factors are:
- Long-term use of alcohol and tobacco smoke
- Very hot food and drinks
- Poor nutrition, especially lack of fresh fruits and vegetables
- Certain viral infections
- Chronic irritation of the esophagus
For **adenocarcinoma** the following applies:
- GERD (gastroesophageal reflux disease), where stomach acid regularly flows back into the esophagus
- Obesity
- Smoking
- A precursor condition called Barrett's esophagus, in which the normal tissue of the esophagus changes due to prolonged exposure to acid
It is important to know that having risk factors does not mean you will get cancer. Many people with the same factors never develop the disease.
How the disease progresses
Esophageal cancer often grows quietly. The tumor can spread in three directions: deeper into the esophageal wall, around the esophagus, or along the esophagus up and down. As the tumor grows, it can narrow the opening of the esophagus more and more.
The cancer can also spread to nearby lymph nodes (in the chest and abdomen) and then to organs further away such as the lungs, liver and bones. The earlier a tumor is detected, the better the chances for treatment.
The disease course is individual: some tumors grow more slowly than others. This depends on the type of cancer, how aggressive it is (determined under the microscope) and the general health of the patient.
Symptoms by phase
**Early stage (often no symptoms)**
- Possibly no noticeable complaints
- Sometimes discovered unknowingly during examinations for something else
**When it becomes more serious**
- Difficulty swallowing, especially solid food
- Pain or discomfort behind the breastbone when eating
- The feeling that food "gets stuck"
- Involuntary vomiting
- Declining appetite through mental association
- Weight loss (sometimes significant)
- Vomiting with blood (blood in vomit)
**When more extensive**
- Permanent pain behind the breastbone or in the back
- Hoarseness, rough voice (may indicate spread to the nerve that controls the vocal cords)
- Persistent cough (can result from effects on the airways)
- Fatigue and weakness due to malnutrition
Not every complaint means cancer; common conditions can cause similar symptoms. A doctor can determine what is necessary.
What it means for daily life
A diagnosis of esophageal cancer brings major changes:
**Eating and drinking**
Swallowing can become difficult. Many patients have to switch to soft food, soups, drinks or nutritional supplements. This can be emotionally stressful, because eating and drinking go far beyond nutrition alone. Some people experience that the social aspect of meals is lost.
**Treatment and hospitalization**
Depending on the stage, treatments can last weeks to months. This may include chemotherapy, radiotherapy, surgery or combinations. Hospital visits and side effects can significantly disrupt daily life.
**Loss of income**
Many patients are unable to work (temporarily or permanently) due to fatigue, treatment side effects, or physical limitations.
**Psychological burden**
A cancer diagnosis affects you emotionally. Fear, sadness, anger, and uncertainty are normal reactions. This can have a major impact on relationships, family, and friends.
**Nutrition and weight**
Weight loss is common and can become medically problematic. This requires attention from dietitians and medical professionals.
Outlook
The outlook for esophageal cancer varies greatly depending on the situation. An important factor is the **stage** (how large and extensive the tumor is). Tumors detected early generally have better outcomes than those in advanced stages.
Worldwide, five-year survival rates (at population level, not for one individual) are around 15–20%, but this varies greatly by region and type of cancer. In countries with more early detection, these rates are higher. These percentages say nothing about your individual situation — much depends on your age, overall health, type of tumor, and the treatment offered.
Recent developments in medicines (particularly immunotherapy) offer new possibilities for some patients, especially in combination with chemotherapy or radiation. Much research focuses on better ways to detect tumors early and provide more personalized treatments.
Although esophageal cancer is serious, there are people who live long lives with or after the disease, especially if treatment takes place early.
Frequently asked questions
**Is esophageal cancer hereditary?**
Most cases are not hereditary. However, certain hereditary syndromes can increase the risk. If esophageal cancer runs in your family, genetic counseling may be helpful. Discuss this with your doctor.
**Can I eat after treatment?**
This depends on what procedure you've had. After certain procedures, eating may remain difficult. Many patients learn to adapt to changes in their eating patterns. A dietitian can help with this.
**How is esophageal cancer diagnosed?**
This is usually done via endoscopy (a thin tube inserted into the esophagus) with a tissue sample, followed by imaging (CT, PET scan) to determine how large and extensive the tumor is.
**What if I don't want to be treated?**
This is your own choice. However, without treatment, esophageal cancer will usually progress. A conversation with your doctor about your wishes, questions, and concerns is crucial. Palliative care (focused on comfort) is always an option.
