Symptoms of Stomach Cancer

Common Symptoms of Stomach Cancer

Stomach cancer, also known as gastric cancer, often presents with a variety of symptoms that can be easily mistaken for less serious conditions. The most frequently reported symptoms include indigestion or heartburn, also known as dyspepsia, which is a common early sign . Patients may also experience nausea and a feeling of fullness or bloating even after consuming small amounts of food . Abdominal pain, particularly in the stomach or abdomen, is another prevalent symptom .

Weight Loss and Appetite Changes

Unexplained weight loss is a significant symptom of stomach cancer, often accompanied by a loss of appetite . This weight loss can be rapid and substantial, reflecting the body's response to the cancerous growth. Additionally, patients may report a general sense of weakness and fatigue, which can be attributed to both the cancer itself and the associated nutritional deficiencies.

Difficulty Swallowing and Anemia

Difficulty swallowing, known as dysphagia, is another symptom that can indicate the presence of stomach cancer, particularly when the tumor is located near the esophagus . Anemia, often resulting from chronic internal bleeding, is also a common finding in stomach cancer patients. This can lead to symptoms such as fatigue, pallor, and shortness of breath .

Gastrointestinal Symptoms

Gastrointestinal symptoms are prevalent among stomach cancer patients. These include melena (black, tarry stools) due to gastrointestinal bleeding, and vomiting, which may sometimes be severe . Some patients may also experience postprandial pain, which is pain occurring after eating.

Unusual Presentations

In some cases, stomach cancer can present with atypical symptoms. For instance, severe low back pain and lumboischialgia (pain radiating from the lower back down the leg) have been reported as initial symptoms in rare cases. Additionally, stomach cancer can sometimes present with symptoms of distant metastasis, such as portal vein thrombosis, which is a blockage of the vein that carries blood from the intestines to the liver.

Conclusion

Stomach cancer presents with a wide range of symptoms, many of which overlap with less serious conditions. Common symptoms include indigestion, nausea, abdominal pain, unexplained weight loss, and difficulty swallowing. Gastrointestinal symptoms such as melena and vomiting are also prevalent. In rare cases, unusual symptoms like severe back pain may be the first indication of the disease. Early recognition and consultation with a healthcare provider are crucial for timely diagnosis and treatment.
