The symptoms of esophageal cancer vary according to the severity and location of the tumour within the esophagus. During the early stage, minor or no noticeable symptoms appear, which makes initial diagnosis challenging. As it progresses, symptoms become more visible and start interfering with simple activities like eating and swallowing and degrade the overall quality of life.
Knowing this serious medical condition helps in recognising warning signs and seeking timely medical help. Understanding esophagitis causes may also help distinguish inflammatory conditions of the esophagus from more serious diseases such as esophageal cancer.
What is esophageal cancer?
Understanding esophageal symptoms helps you learn more about this disease. This cancer develops when abnormal cell growth happens uncontrollably within the esophagus lining. These cells may start invading the deeper layers of the esophageal wall and spread to the nearby lymph nodes/distant organs if not addressed duly.
The esophagus is the body part that plays a crucial role in transporting food and fluids from the mouth to the stomach. With cancer development, the pathway narrows, and it becomes difficult to swallow. Early detection allows access to better treatment outcomes. Although individuals can be affected by esophageal cancer at any age, it is more common among the elderly and is associated with certain lifestyle and medical factors.
Early Symptoms of Esophageal Cancer
The commonly observed early signs of esophageal cancer include the following.
- Fatigue
- Persistent cough
- Hoarseness
- Unexplained weight loss
- Frequent regurgitation of food
- Persistent indigestion/heartburn
- Mild chest discomfort/pressure
- Feels like food got stuck in the chest
- Troubles in swallowing solid foods
These symptoms don’t develop overnight but gradually, thus making individuals delay medical attention.
NOTE: Many times, the early symptoms of esophageal cancer may be mistaken for acid reflux because of its overlapping nature. It is thus required to visit the physician for help regarding persistent ones.
Types of esophageal cancer
The types of esophageal cancer vary according to the cell type they emerge from.
- Adenocarcinoma – it develops from glandular cells (found at the lower end of the esophagus) and is commonly associated with chronic gastroesophageal reflux disease (GERD) and Barrett’s esophagus.
- Squamous Cell Carcinoma – It begins from the flat cells located at the upper and middle sides of the esophagus. The risk is high among tobacco users and people with heavy alcohol habits.
- Small Cell Carcinoma of the Esophagus – This type of esophagus cancer is rare but aggressive, emerging from neuroendocrine cells.
- Sarcoma – It develops from the connective tissues, like muscle/blood vessels.
- Lymphoma is extremely rare and originates from the lymphatic tissues.
- Melanoma of the Esophagus – it is among the rarest forms of esophageal cancers.
What Are the Causes of Esophageal Cancer?
Differentiating esophageal spasms from esophageal cancer symptoms helps in identifying the overlapping signs. While the cause of esophageal spasms isn’t clearly understood, it is believed to develop through a combination of genetic changes and long-term damage to the Esophaegal lining.
The common contributing factors are as follows.
- Tobacco use
- Obesity
- Heavy alcohol intake
- Chronic acid reflux (GERD)
- A diet low in fruits or vegetables
- Barrett’s Esophagus
- Specific inherited genetic syndrome
- Exposure to certain environmental carcinogens
- Previous radiation therapy, including the chest
Not all individuals with these risk factors develop cancer. Some are even diagnosed with Esophaegal cancer without any known factors.
Esophageal cancer risk factors
The most well-known risk factors of Esophaegal cancer are shared below.
- Obesity
- Smoking
- Male gender
- Barrett’s Esophagus
- Older people (55+ years)
- Poor dietary habits
- Family history of certain cancers
- Long-standing gastroesophageal reflux disease
- Past caustic injury to the Esophagus
FACT: Some individuals develop this cancer without any known factors, while others who have some factors are not necessarily diagnosed with Esophagus cancer. Regular health monitoring at intervals helps in outlining persistent symptoms and availing medical help at the right time.
Esophageal Cancer Treatment
The following are possible treatment options for esophageal cancer. Your healthcare provider shall confirm the diagnosis before suggesting a specific one. Once prescribed, strictly follow the dosage indications for achieving the desired outcome. Do not make any self-alterations or switch medications without medical guidance.
Surgery
It is mostly advised when esophageal cancer is localised. The procedure involves removing the esophagus entirely, together with the nearby lymph nodes, or partially. Surgical reconstruction eases the passage of food and fluids smoothly.
Radiation Therapy
In this therapy, high-energy beams are used to destroy cancer cells. Radiation therapy may be advised before or after the surgery as part of advanced disease management for relieving symptoms like trouble swallowing.
Chemotherapy
Medications are prescribed in chemotherapy to destroy the rapidly multiplying cells. It can be recommended before or after the surgery or for advanced cancer management.
The common chemotherapy drugs for esophageal cancer are as follows. They are advised differently according to the cancer stage and medical requirements.
Targeted Therapy
In targeted therapy, the medications attack the particular molecular structure of the cancer cells while minimising the damage to healthy tissues.
Immunotherapy
Immunotherapy helps the immune system itself detect and destroy cancer cells. It is often advised for advanced or metastatic esophageal cancer management.
Endoscopic Treatments for Early-Stage Cancer
This procedure is minimally invasive, ideal for the very early stage of esophageal cancer.
When to see a doctor?
After discussing almost everything related to the symptoms of esophageal cancer, it is now clear when to seek medical help. Progressive/persistent difficulties in swallowing or unexplained weight loss should not be ignored. Medical evaluation becomes necessary when the following applies.
- Discomfort prevails for several weeks consistently
- Symptoms continue despite treating acid reflux
- The persistent symptoms are followed by blood in the vomit or black stools
- Significant weight loss occurs
- Chest discomfort becomes an everyday thing
TIP: Try to spot the abnormalities in your body and don’t ignore any persistent signs. Early diagnosis increases the treatment success rate and improves long-term outcomes.
FAQs on Symptoms of Esophageal Cancer
Are esophageal cancer symptoms different in men and women?
No, the symptoms of esophageal symptoms are gender-neutral, but the risk factors, lifestyle habits, and age can affect the experience with the disease.
Does esophageal cancer always cause difficulty swallowing?
No. Although it is the most common symptom, it may not seem troubling at the earlier stage. Some patients may witness chest discomfort, heartburn, chronic cough, or unexplained weight loss.
How do esophageal cancer symptoms differ from acid reflux?
The symptoms of esophageal cancer and acid reflux may overlap, but the former seems to worsen over time. For instance, difficulties in swallowing and sudden weight loss.
What are the advanced symptoms of esophageal cancer?
The advanced symptoms of Esophaegal cancer can be swallowing difficulties, discomfort in eating solid foods, chest pain, persistent vomiting, significant weight loss, cough after swallowing, hoarseness, etc.
How Fast Do the Symptoms of Esophageal Cancer Progress?
The progression pace varies according to the cancer type, stage, and individual factors. For some, the symptoms may develop over a few months, while others undergo drastic changes.
Conclusion
We hope this insightful read about the symptoms of esophageal cancer helped you understand this medical condition better. The early signs are often misunderstood as acid reflux, but require medical attention when they persist longer than usual. However, you can only start treatment after a comprehensive discussion with a medical expert, a confirmed diagnosis & a tailored treatment plan.
