Acid reflux, also known as gastroesophageal reflux disease (GERD), is a common condition where stomach acid flows back into the oesophagus (food pipe) leading to symptoms like heartburn, regurgitation, and a sour taste in the mouth. While occasional acid reflux is normal, chronic reflux can damage the oesophagus over time and, in some cases, increase the risk of oesophageal cancer. At Zanish Cancer Hospital, we emphasize the importance of understanding the connection between acid reflux and oesophageal cancer to encourage early diagnosis and preventive care.
Understanding Acid Reflux and GERD
Acid reflux occurs when the lower oesophageal sphincter (LES), a muscle that normally keeps stomach acid from rising back into the oesophagus, becomes weakened or relaxes inappropriately. This allows acid to irritate the lining of the oesophagus, causing uncomfortable symptoms such as:
- • Heartburn (a burning sensation in the chest)
- • Regurgitation (a sour or bitter taste)
- • Difficulty swallowing
- • Chest pain
For people with GERD, these symptoms are persistent, occurring more than twice a week. Chronic exposure of the oesophageal lining to stomach acid can lead to inflammation and cellular changes that increase the risk of developing oesophageal cancer.
The Connection Between GERD and Oesophageal Cancer
One of the most concerning risks of untreated GERD is its potential to lead to a condition called Barrett’s oesophagus. In Barrett’s oesophagus, the tissue lining the oesophagus changes to resemble the lining of the intestine, a process known as metaplasia. This condition is considered a precancerous state and can progress to oesophageal adenocarcinoma, a type of cancer.
In fact, GERD and Barrett’s oesophagus are among the leading risk factors for oesophageal adenocarcinoma, a form of cancer that begins in the glandular cells of the oesophagus. The progression from GERD to Barrett’s oesophagus and then to oesophageal cancer highlights the importance of managing acid reflux symptoms effectively and undergoing regular medical monitoring if you are at risk.
Recognizing the Symptoms of Oesophageal Cancer
Early detection of oesophageal cancer is essential for effective treatment. Symptoms may be subtle initially but often worsen as the cancer progresses. Key symptoms to watch for include:
- • Difficulty swallowing (dysphagia)
- • Unintentional weight loss
- • Persistent chest or back pain
- • Hoarseness or chronic cough
- • Chronic indigestion or heartburn that doesn’t improve with medication
If you experience these symptoms, it’s important to seek medical evaluation as soon as possible.
Preventing Oesophageal Cancer Through GERD Management
At Zanish Cancer Hospital, we believe prevention is the best approach. Here are key steps for managing GERD and lowering the risk of oesophageal cancer:
Lifestyle Changes
Simple adjustments like eating smaller, more frequent meals, avoiding late-night eating, and maintaining a healthy weight can help reduce acid reflux. Avoiding trigger foods, such as spicy, fatty, or acidic foods, as well as caffeine and alcohol, can also help manage GERD symptoms.
Quit Smoking and Limit Alcohol
Smoking weakens the LES and increases acid production, both of which worsen GERD. Limiting alcohol intake also reduces irritation of the oesophagus and helps prevent cancerous changes in the cells.
Medications
Proton pump inhibitors (PPIs) and H2 blockers are medications that reduce stomach acid production, providing relief from acid reflux and helping to protect the oesophagus from damage. If you have persistent symptoms, talk to your doctor about these options.
Regular Check-Ups and Screening
For individuals with chronic GERD, regular check-ups are essential. Your doctor may recommend an endoscopy to check for inflammation or abnormal cellular changes, particularly if Barrett’s oesophagus is a concern. This allows for early detection and treatment, reducing the risk of progression to cancer.
Know Your Family History
Some people may have a genetic predisposition to Barrett’s oesophagus or oesophageal cancer. If you have a family history of these conditions, be vigilant about monitoring GERD symptoms and discuss your risk with your healthcare provider.
While acid reflux is common, untreated or chronic GERD can increase the risk of oesophageal cancer. By recognizing the symptoms, adopting preventive lifestyle changes, and seeking regular medical advice, you can take control of your health and reduce the risks associated with acid reflux. At Zanish Cancer Hospital, our goal is to empower patients through awareness, early detection, and compassionate care, helping individuals lead healthier lives free from the risks of chronic GERD and oesophageal cancer.
