Esophageal cancer usually progresses in a barely noticeable way in the early stages, which means that many cases are only identified in more advanced stages. Although it is not among the most common digestive tumors, it presents aggressive behavior and a high mortality rate globally.
In the context of Abril Azul Claro, a campaign aimed at raising awareness about the disease, understanding the factors that hinder early diagnosis and recognizing initial signs becomes essential to increase the chances of detection in more treatable stages.
Why diagnosis is often delayed
The esophagus is the organ responsible for carrying food from the throat to the stomach and has a relevant characteristic from a clinical point of view. In the initial stages of changes, it rarely causes pain or obvious symptoms. This pattern allows tumors to develop for long periods without causing noticeable discomfort.
When symptoms appear, they generally indicate that the disease is already at a more advanced stage, which reduces the possibilities of treatment with better results.
Signs that deserve attention
The main symptom associated with it is dysphagia, characterized by difficulty swallowing. This condition usually evolves progressively, initially with difficulty eating solid foods, progressing to pasty foods and, in more advanced stages, even liquids.
Other signs that require attention include unexplained weight loss, sensation of food stuck in the throat or chest, pain when swallowing, persistent hoarseness, frequent coughing, episodes of choking and regurgitation.
It is common that, faced with these symptoms, many people adapt their diet, start chewing more or avoid certain foods, which can delay the search for medical evaluation and contribute to late diagnosis.
Risk factors associated with the disease
The development of esophageal cancer is generally related to continuous aggression to the esophageal tissue over time.
Smoking and alcohol consumption are among the main causes, especially for squamous cell carcinoma. Cigarettes contain substances with direct carcinogenic potential, while alcohol acts as a facilitator of this process. When combined, these factors significantly increase the risk.
Chronic gastroesophageal reflux also plays an important role. Frequent exposure of the esophagus to stomach acid can cause ongoing inflammation and lead to cellular changes known as Barrett’s esophagus, a condition considered pre-malignant and associated with an increased risk of adenocarcinoma.
Obesity also contributes to this scenario, both through increased reflux and metabolic changes that favor inflammatory processes and the development of tumors.
Other relevant factors include age over 50 years, higher incidence in men, diet poor in fruits and vegetables, family history and, possibly, frequent consumption of foods at very high temperatures.
What contributes to prevention
Prevention measures involve stopping smoking, reducing or eliminating alcohol consumption, maintaining a healthy weight, adequately treating reflux and eating a balanced diet, rich in fiber, fruits and vegetables.
Attention to persistent symptoms is also essential. Difficulty swallowing should not be considered normal, nor should frequent episodes of heartburn or unexplained weight loss.
In these cases, medical evaluation is necessary. A is the main exam used, as it allows direct visualization of the esophagus and the performance of biopsies when necessary.
Who should investigate even without symptoms
Some groups are at higher risk and may benefit from closer medical monitoring, even in the absence of symptoms. These include people with long-term gastroesophageal reflux, patients with Barrett’s esophagus and individuals with multiple risk factors, such as the association of smoking and alcohol consumption.
In these situations, follow-up may include periodic examinations, according to medical evaluation.
The importance of observing changes
Esophageal cancer presents an aggressive evolution not only due to its biological characteristics, but also due to the way it manifests itself over time. The absence of initial symptoms requires attention to subtle changes in eating and swallowing patterns.
Changes in the way you swallow, the sensation of food standing still or persistent discomfort should not be ignored. Early identification can significantly modify the course of the disease.
