Symptoms of Stomach Cancer

Stomach cancer is a common health issue in today's world. It often progresses silently in the early stages, but when detected in time, it becomes treatable. Knowing the symptoms and signs of stomach cancer can pave the way for early diagnosis and treatment. Therefore, being aware of the key symptoms that may indicate stomach cancer, as well as its risk factors and the subtle yet critical signs, is crucial.

What is Stomach Cancer?

Stomach cancer occurs as a result of the uncontrolled growth of cells in the lining of the stomach. It often begins in the cells lining the inner walls of the stomach. Adenocarcinoma is the most common type of stomach cancer and originates from the glandular cells in the stomach wall. Symptoms may vary depending on the type and stage of cancer, making it vital to understand the signs and symptoms of stomach cancer correctly.

Symptoms and Signs of Stomach Cancer

The symptoms of stomach cancer often appear as mild and hard-to-detect in the initial stages. However, as the disease progresses, the symptoms become more severe. Here are the primary symptoms to watch out for:

Loss of Appetite and Unexplained Weight Loss

One of the symptoms of stomach cancer is a loss of appetite and sudden weight loss. A noticeable decrease in eating habits or a constant feeling of fullness after eating may indicate stomach cancer. If this condition persists over time, it is important to consult a specialist.

Abdominal Pain and Discomfort

Pain in the abdominal area, especially in the upper abdomen, is a common symptom of stomach cancer. This pain often worsens after eating and may persist over time.

Bloating and Indigestion

Individuals with stomach cancer may frequently experience bloating and indigestion. The feeling of a full stomach or discomfort, especially after meals, may signal a problem with stomach health.

Nausea and Vomiting

Nausea and vomiting are other common symptoms of stomach cancer. Vomiting may sometimes contain blood, which could indicate advanced stages of stomach cancer. Ignoring such a symptom may allow the disease to progress.

Bloody Stool or Melena

The presence of blood in the stool is an important sign of stomach cancer. Black, tarry stools (melena) can be a sign of bleeding in the stomach or intestines. This situation requires urgent medical intervention.

Difficulty Swallowing (Dysphagia)

Particularly if the cancer affects the upper part of the stomach, difficulty swallowing may occur. Pain while swallowing or a sensation of food getting stuck in the throat can be signs of advanced stomach cancer.

Persistent Fatigue and Weakness

Stomach cancer can lower the body's energy levels, leading to excessive fatigue and weakness. The primary cause of this is the blood loss or the decreased absorption of nutrients caused by the condition.

Symptoms Related to Stomach Bleeding

Stomach cancer can cause bleeding in the stomach wall. These bleedings often begin mildly but can become severe in advanced stages. Symptoms such as sudden dizziness, fainting, or heart palpitations can also develop due to stomach bleeding.

Early Symptoms of Stomach Cancer

The early-stage symptoms of stomach cancer are usually mild and non-specific. In some cases, there may be no symptoms at all. Key early-stage symptoms to be aware of include:

Frequent indigestion and heartburn
Discomfort after eating
Mild nausea
Persistent fatigue
Appetite loss without a clear cause

These symptoms may also be related to other stomach disorders. However, if such symptoms persist, consulting a doctor is essential.

Advanced Symptoms of Stomach Cancer (Stage 4, Metastatic Stomach Cancer)

As stomach cancer progresses, symptoms become more complex. If the cancer spreads beyond the stomach, the following symptoms may occur:

Yellowing of the skin (jaundice)
Abdominal swelling (ascites) due to fluid buildup
Bone pain
Swollen lymph nodes
Shortness of breath

These symptoms indicate that the cancer may have spread to other organs and require immediate medical attention.

Risk Factors for Stomach Cancer

Certain individuals are at higher risk of developing stomach cancer. Risk factors include:

Genetic predisposition: People with a family history of stomach cancer have a higher risk.
Helicobacter pylori infection: This bacterium causes inflammation in the stomach lining, which can lead to cancer.
Smoking and alcohol consumption: Smoking and excessive alcohol consumption can increase the risk of stomach cancer.
Dietary habits: Consuming large amounts of salty, smoked, and processed foods increases the risk.
Age and gender: Older age and being male are factors that increase the risk of stomach cancer.

Ways to Prevent Stomach Cancer

Preventing stomach cancer involves adopting a healthy lifestyle and regular check-ups:

Healthy diet: Follow a diet rich in fresh fruits and vegetables.
Avoid tobacco products: Smoking significantly increases the risk of stomach cancer.
Limit alcohol consumption: Reduce alcohol intake to a minimum.
Regular health check-ups: Individuals with a family history of stomach cancer should undergo regular screenings.
Treatment of Helicobacter pylori infection: Early treatment of this infection serves as a protective measure against stomach cancer.
