Oesophageal cancer is the 8th most common cancer worldwide. This disease impacts the oesophagus organ, a vital part of the digestive system, and could spread to other regions of the body.
In our efforts to spread awareness, this guide provides comprehensive insights about this cancer. We will cover the types, symptoms, causes and risk factors, diagnosis, treatment, and prevention tips.
We aim to equip individuals with the knowledge needed to combat and cope with oesophageal cancer, helping them to stay informed throughout their journey.
What is Oesophageal Cancer?
Oesophageal cancer is a disease where cancer cells (tumours) form in the lining of the oesophagus. The oesophagus is a long tube which connects and helps to transfer food from the throat to the stomach.
This disease is more common in men than women, ranking as the 7th most common cancer in men and the 13th most common in women worldwide.
The symptoms of oesophageal cancer are usually only noticeable once the cancer has spread. This disease has been associated with smoking, drinking alcohol, and conditions such as Barrett oesophagus.
Types of Oesophageal Cancer
Here are two common types of oesophageal cancer:
Adenocarcinoma
This cancer starts in the glandular cells in the lining of the oesophagus, which produce fluids such as mucus. It usually develops in the lower part of the oesophagus.
Adenocarcinoma is the most common type of oesophageal cancer. This condition has been linked to Barrett’s Oesophagus, obesity, and gastroesophageal reflux disease (GERD).
Squamous cell carcinoma
This cancer starts in the squamous cells, which are thin, flat cells on the lining of the oesophagus. It usually develops in the upper and middle part of the oesophagus.
This disease has been linked with smoking and drinking excessive amounts of alcohol.
Stages of Oesophageal Cancer
There are two systems which provide insight into the severity and extent of cancer spread. These systems assist doctors in deciding the best treatment for you.
The TNM System
This system is the most common method used in staging oesophageal cancer. TNM stands for tumour, node, and metastasis:
- Tumour (T): Indicates the size of the tumour. Grading from T1 to T4, with higher grades denoting larger tumour size.
- Node (N): Indicates whether the cancer has spread to the lymph nodes. Grading from N0 to N3, with higher grades denoting a higher number of affected lymph nodes.
- Metastasis (M): Indicates whether the cancer has spread to other body parts. Grading from M0 to M1, with M1 denoting that the cancer has spread to other parts of the body.
The Number System
This system comprises 5 main stages, from stage 0 (High grade dysplasia) to stage 4:
- Stage 0 (High grade dysplasia): Highly abnormal cells are found in the inner lining of the oesophagus.
- Stage I: The cancer is confined to the thick muscle wall of the oesophagus.
- Stage II: The cancer may have reached the outer layer of the oesophagus and 1 or 2 nearby lymph nodes.
- Stage III: The cancer may have spread beyond the oesophagus into nearby tissues and up to 6 nearby lymph nodes.
- Stage IV: The cancer is advanced, possibly spreading to other organs or body structures, lymph nodes or body parts (e.g., lungs or liver).
Symptoms
Here are a few symptoms of oesophageal cancer:
- Difficulty swallowing
- (Unexplained) Weight loss
- Chest pain or pressure
- Cough or hoarseness
- Indigestion or heartburn
- Vomit with blood
- Stools that are black or bloody
- A lump under the skin
Do note that these symptoms could also be caused by other medical conditions. Consult your doctor immediately if you notice any of these signs, and obtain a proper diagnosis.

Causes and Risk Factors
The exact cause of oesophageal cancer has not been found. However, doctors have found that the following factors may increase the risk of this disease:
- Smoking
- Drinking alcohol
- Eating a diet low in fruits and vegetables
- Drinking very hot drinks regularly
- Obesity
- Being exposed to certain chemical fumes (e.g., dry cleaning solvents)
- Human papillomavirus (HPV) infection
- Inherited genetic conditions (e.g., Cowden syndrome)
- Medical conditions (e.g., Barrett’s oesophagus, gastroesophageal reflux disease, achalasia)
- Personal or family history of cancer
Therefore, if you fall into any one of these categories, discuss with your doctor to decide the next step. We also recommend scheduling a health screening to ensure early detection.

Diagnosis
Your healthcare provider may use the following methods to diagnose oesophageal cancer:
- Physical Exam and Medical History: A physical examination of the body is done, where the doctor checks for possible signs of cancer. They will also take note of any past diseases and treatments.
- Barium Swallow Test: You will need to swallow a liquid called barium. The radiographer will perform an X-ray while you are swallowing. Barium can make your oesophagus appear more clearly on the image, helping doctors identify any abnormal formations in your oesophagus.
- Computed Tomography (CT) Scan: This imaging test creates a detailed picture of your body. It helps the doctor check if the oesophageal cancer has spread to different parts of the body, like your chest and stomach.
- Gastroscopy: A thin, flexible tube with a lens at the end (endoscope) is inserted into your mouth and down the oesophagus. The specialist will search for any issues. They may collect a small sample (biopsy) which will be sent to the laboratory and checked for cancer.
How is Oesophageal Cancer Treated?
The type of treatment will depend on the stage of the cancer. Here are some treatments your doctor may choose:
- Surgery: Surgery is often recommended, especially in early-stage oesophageal cancer. The goal is to remove the tumour and surrounding affected tissues. The surgeon may remove part or most of the oesophagus, and other parts of nearby organs – where the cancer has spread.
- Radiation Therapy: Uses high-energy beams to destroy cancer cells. It may be used alone or in combination with chemotherapy to treat early-stage cancer. It can also be used to alleviate the symptoms of advanced cancer.
- Chemotherapy: Involves the use of medications to kill cancer cells or slow their growth. It is often used in combination with other treatments, such as surgery or radiotherapy, to improve outcomes. Similar to radiotherapy, it can also be used to alleviate the symptoms of advanced cancer.
- Targeted Therapy: Uses medicines that attack certain mutations in cancer cells, causing them to die. It may be used alongside chemotherapy to treat advanced cancer cases that can’t be surgically removed, or recurrent oesophageal cancer cases.
- Immunotherapy: Uses medicines that help your immune system find and kill the cancer cells. It may be used before or after surgery. Similar to targeted therapy, it can also be used to treat advanced cancer cases where surgery is not an option, or recurrent oesophageal cancer cases.
Living with Oesophageal Cancer
Oesophageal cancer can cause drastic changes to your life. Here are a few ways to manage and navigate this period:
Problems with Eating
Oesophageal cancer can make eating more difficult. Therefore, we recommend breaking up your meals into smaller, more frequent amounts. It is also advisable to eat slowly, and take a sip of water in between bites.
Another good solution is a soft diet, where the food is much easier to swallow.
For example, softening meat and vegetables (cooking them longer), adding more sauces and gravies to food, and finely dicing meats and vegetables. Your diet may also include more soups and smoothies.
To make the process easier, dieticians can provide support and coping methods, ensuring your body gets all the necessary nutrients.
You may ask your doctor to refer you to a licensed dietician, who will then provide tailored solutions throughout the diagnosis, treatment, and aftercare stages.
Mental Health and Support
Receiving news about the diagnosis, undergoing the treatment, and coping with life after treatment can be tough on your mental health.
You may experience feelings of loss, worry, anger, and fear throughout this time. These are all perfectly normal responses, and will affect each individual differently.
Therefore, it’s important to meet up with people who can support you throughout this time, such as mental health professionals, trusted friends and family, or cancer support groups.
You may also voice these feelings out to your doctor, who can share relevant resources and direct you to the right professionals.
Measures to Prevent Oesophageal Cancer
Here are a few ways to reduce your risk of oesophageal cancer, and enhance overall health:
1. Regular oesophageal cancer screening
If you have Barrett oesophagus, consider scheduling regular screenings with your healthcare provider. The reason being: this precancerous condition increases the risk of oesophageal cancer.
During the screening, the doctor may perform tests such as a CT scan or endoscopy to check your oesophagus for signs of cancer.
2. Maintain a healthy weight
Individuals who are overweight have a higher chance of getting GERD, as the excess weight may force acid into the oesophagus. This increases the likelihood of developing oesophageal cancer.
Therefore, incorporate a balanced diet and regular exercise in your daily routine. You may consult a doctor or dietician to help create an effective weight management plan.
3. Limit or stop alcohol intake
Drinking excessive amounts of alcohol increases your risk of squamous cell oesophageal cancer. Therefore, we recommend limiting or stopping this habit entirely.
Here is a guideline for moderate drinking: men should limit themselves to a maximum of two drinks a day, while women should stick to just one drink.
4. Include more fruits and vegetables in your meals
Fruits and vegetables have been found to have an anticarcinogenic effect, thus reducing the risk of developing oesophageal cancer. Therefore, eat a healthy diet rich in this food category.
5. Stop smoking
Smoking increases your risk of squamous cell oesophageal cancer. We recommend consulting your doctor on methods to quit smoking. They may recommend nicotine replacement products and medicines to help ease the process.
6. Prevent HPV Infection
HPV infections, specifically the ones contracted via oral sex, can increase your risk of oesophageal cancer. Therefore, practise safe sex (e.g., using condoms) and get vaccinated (if you are eligible) to reduce this risk.
7. Manage medical conditions that put you at risk
Get treatment for certain conditions, such as GERD and achalasia, which are known to impact the oesophagus and increase the risk for oesophageal cancer. These conditions can be treated with medication, injections, and surgery.
