Overview of Stomach Cancer

 

Stomach cancer, also known as gastric cancer, originates in the lining of the stomach and can develop into a malignant tumor. It is a complex disease characterized by the abnormal growth of cells in the stomach, which can spread to other parts of the body. This type of cancer is often classified based on the location within the stomach where it begins, such as the cardia (upper part), body (middle part), or antrum (lower part). Additionally, it can be categorized according to the type of cells involved, with adenocarcinoma being the most common form. Understanding the basics of stomach cancer is essential for recognizing its potential impact and seeking timely medical intervention.

​

The progression of stomach cancer typically occurs over several years. During the early stages, the symptoms might be subtle or even nonexistent, making early detection challenging. As the cancer advances, it can invade deeper layers of the stomach wall and spread to nearby organs or lymph nodes. This progression underscores the importance of awareness and vigilance regarding any unusual digestive symptoms, as early-stage stomach cancer is more treatable compared to advanced stages. Despite advances in medical research and treatment, stomach cancer remains a significant health challenge worldwide.

​

In Singapore, stomach cancer poses a notable health concern, with various factors contributing to its incidence. Lifestyle choices, dietary habits, and genetic predispositions all play roles in the development of this disease. Moreover, the public's awareness and understanding of stomach cancer are critical in promoting early detection and seeking appropriate medical care. By exploring the symptoms, risk factors, individuals can better navigate the complexities of this illness and take proactive steps toward their health and well-being.

Stomach Cancer Statistics in Singapore

 

Stomach cancer is one of the top ten most common cancers in Singapore, affecting both men and women. According to the Singapore Cancer Registry, the incidence of stomach cancer has shown a gradual decline over the past few decades, yet it remains a significant health concern. This decline can be attributed to improved public health measures, better dietary practices, and increased awareness of the disease. Despite this positive trend, stomach cancer still accounts for a considerable number of cancer-related deaths in the country, highlighting the need for continued vigilance and education.

​

The statistics reveal that stomach cancer is more prevalent among older adults, particularly those aged 60 and above. However, it can also occur in younger individuals, albeit less frequently. The gender distribution shows a higher incidence rate in men compared to women, with lifestyle factors such as smoking and alcohol consumption potentially contributing to this disparity. Ethnic differences also play a role, with varying rates observed among the Chinese, Malay, and Indian populations in Singapore. These demographic insights are crucial for tailoring public health initiatives and screening programs to address the specific needs of different groups.

​

Another important aspect of stomach cancer statistics is the survival rate, which depends largely on the stage at diagnosis. Early-stage stomach cancer, when confined to the stomach lining, has a significantly higher survival rate compared to advanced stages where the cancer has spread to other organs. This underscores the critical importance of early detection and timely intervention. Efforts to improve survival rates include promoting regular screenings, educating the public about early symptoms, and ensuring access to advanced medical treatments. By understanding the epidemiology of stomach cancer in Singapore, healthcare professionals and policymakers can better strategize to combat this disease effectively.

Common Symptoms of Stomach Cancer

 

Recognizing the symptoms of stomach cancer is pivotal for early detection and successful treatment. Unfortunately, the early signs can be vague and easily mistaken for less serious conditions such as gastritis or peptic ulcer disease. One of the most common early symptoms is persistent indigestion or heartburn that does not respond to over-the-counter medications. This discomfort, often described as a burning sensation in the upper abdomen, can be accompanied by bloating, nausea, and a feeling of fullness after eating small amounts of food. These symptoms may be intermittent and vary in intensity, leading many individuals to overlook them.

 

As the disease progresses, more alarming symptoms may emerge, signaling the need for immediate medical attention. Unexplained weight loss is a significant red flag, especially when it occurs without any changes in diet or exercise habits. This weight loss can be accompanied by a loss of appetite and an aversion to certain foods, particularly meat. Another concerning symptom is difficulty swallowing, known as dysphagia, which may indicate that the tumor is obstructing the passage of food through the stomach or esophagus. Additionally, individuals may experience chronic fatigue, weakness, and anemia, resulting from internal bleeding caused by the tumor.

​

Advanced stages of stomach cancer can present with more severe symptoms, including persistent abdominal pain, vomiting (sometimes with blood), and noticeable swelling or lumps in the abdomen. Jaundice, characterized by yellowing of the skin and eyes, may occur if the cancer spreads to the liver. It is crucial for individuals experiencing any combination of these symptoms to seek medical evaluation promptly. Early diagnosis can significantly improve the prognosis and open up a wider range of treatment options. Being attentive to these signs and understanding their potential implications can empower individuals to take proactive steps toward their health.

​

​

Risk Factors and Causes

 

Several risk factors and causes contribute to the development of stomach cancer, and understanding these can help individuals take preventive measures. One of the primary risk factors is infection with Helicobacter pylori (H. pylori), a bacterium that colonizes the stomach lining and can lead to chronic inflammation and ulcers. Over time, this persistent inflammation can cause cellular changes that increase the risk of cancer. H. pylori infection is common worldwide, and in regions with high prevalence, such as parts of Asia, addressing this infection through appropriate medical treatment is essential in reducing stomach cancer risk.

​

Dietary habits also play a significant role in the development of stomach cancer. Diets high in smoked, salted, and pickled foods are associated with an increased risk, as these foods contain nitrates and nitrites that can be converted into carcinogenic compounds in the stomach. Conversely, a diet rich in fresh fruits and vegetables, particularly those high in antioxidants and vitamins, may offer a protective effect. Smoking and excessive alcohol consumption are additional lifestyle factors that elevate the risk of stomach cancer. Smoking introduces harmful chemicals into the body that can damage the stomach lining, while heavy alcohol use can lead to chronic gastritis and other gastrointestinal issues.

​

Genetic predisposition is another important factor to consider. Individuals with a family history of stomach cancer or certain hereditary conditions, such as Lynch syndrome or hereditary diffuse gastric cancer, have a higher risk of developing the disease. These genetic factors highlight the importance of discussing family medical history with healthcare providers, as they may recommend genetic testing or more frequent screenings for those at elevated risk. Other contributing factors include age (with increased risk in older adults), gender (higher incidence in men), and pre-existing medical conditions such as pernicious anemia or chronic atrophic gastritis. By identifying and addressing these risk factors, individuals can take proactive steps to reduce their likelihood of developing stomach cancer.

​

​

Screening Methods for Stomach Cancer

 

Screening for stomach cancer is a crucial strategy for early detection, especially for individuals at higher risk due to factors such as age, family history, or H. pylori infection. One of the most effective screening methods is gastroscopy, also known as an upper endoscopy. During this procedure, a thin, flexible tube with a camera (endoscope) is inserted through the mouth and into the stomach, allowing the doctor to visually inspect the stomach lining for any abnormal growths or lesions. If suspicious areas are identified, tissue samples (biopsies) can be taken for further examination under a microscope. Gastroscopy is highly sensitive and can detect even small, early-stage cancers that may not be visible on imaging tests.

​

Another valuable screening tool is the barium swallow X-ray, also called an upper gastrointestinal (GI) series. In this test, the patient drinks a barium-containing liquid that coats the stomach lining, making it visible on X-ray images. While this method is less invasive than gastroscopy, it is also less sensitive and may not detect small or early-stage cancers. However, it can be useful for identifying structural abnormalities or large tumors. For individuals who cannot undergo gastroscopy due to medical reasons, the barium swallow X-ray can serve as an alternative screening option.

​

In addition to these primary screening methods, other diagnostic tests may be used to complement the detection process. For example, blood tests to check for anemia or elevated levels of certain tumor markers can provide additional clues about the presence of stomach cancer. Advanced imaging techniques, such as computed tomography (CT) scans or magnetic resonance imaging (MRI), can help assess the extent of cancer spread and guide treatment planning. For populations with a high prevalence of H. pylori infection, testing and treating this bacterium can also serve as a preventative measure. By utilizing a combination of these screening methods, healthcare providers can enhance the accuracy of diagnosis and improve the chances of detecting stomach cancer at an early, more treatable stage.

Importance of Early Detection

 

Early detection of stomach cancer is paramount in improving survival rates and treatment outcomes. When stomach cancer is diagnosed at an early stage, before it has spread beyond the stomach lining, the chances of successful treatment are significantly higher. Early-stage cancers are often localized and can be removed surgically with a high likelihood of complete cure. In contrast, advanced-stage cancers that have metastasized to other organs or lymph nodes are more challenging to treat and often require a combination of therapies, which may only provide palliative relief rather than a cure.

​

The importance of early detection extends beyond just improving survival rates; it also enhances the quality of life for patients. Early-stage cancer treatments are generally less aggressive and have fewer side effects compared to treatments for advanced-stage cancer. For instance, a patient with early-stage stomach cancer may only need a partial gastrectomy (removal of part of the stomach) and can maintain relatively normal digestive function. On the other hand, advanced-stage cancer may necessitate more extensive surgery, such as total gastrectomy (complete removal of the stomach), along with chemotherapy and radiation therapy, which can significantly impact the patient's overall well-being and daily life.

​

Public awareness and education play crucial roles in promoting early detection of stomach cancer. Informing individuals about the common symptoms, risk factors, and available screening methods can encourage them to seek medical advice promptly if they experience any concerning signs. Regular check-ups and screenings for high-risk individuals, such as those with a family history of stomach cancer or chronic H. pylori infection, can lead to earlier diagnosis and better outcomes. Healthcare providers and public health campaigns must continue to emphasize the importance of early detection, as timely intervention can save lives and reduce the burden of stomach cancer on patients and their families.
