Signs and Indicators of Stomach Cancer
Stomach cancer, also known as gastric cancer, can be a silent yet serious health concern. While it may cause various symptoms, these often appear late and can be nonspecific, leading to a delayed diagnosis. Knowing the early signs and symptoms can help individuals be aware of anything unusual.
Common Symptoms of Stomach Cancer
Stomach cancer may manifest through a range of symptoms. These can include abdominal pain or discomfort, especially after meals, persistent indigestion or heartburn, nausea or vomiting, feeling full quickly after eating small amounts, unexplained weight loss, loss of appetite, black or tarry stools (melena) or vomiting blood indicating bleeding, fatigue or weakness due to anemia caused by blood loss, abdominal swelling or fluid buildup in advanced cases, and in some instances, jaundice.
Early Detection Methods
Early detection of stomach cancer is crucial for successful treatment. Methods for early detection include gastroscopic examination (endoscopy), imaging techniques, and liquid biopsies.
Gastroscopic examination is the most definitive method, involving a fiber-optic camera inserted into the stomach for direct visualization and biopsy of suspicious areas. This remains the diagnostic gold standard.
Imaging techniques, such as traditional methods like abdominal X-rays or CT scans, can identify abnormalities but have been limited in early detection. However, new AI-assisted analysis of non-contrast CT scans shows promise, reaching about 85% sensitivity in detecting early stomach tumors and outperforming radiologists by using routine scans as screening tools.
Liquid biopsy using exosomal microRNA signatures is an innovative blood-based test that analyses exosome-based biomarkers. These tests have demonstrated high accuracy and sensitivity for detecting early-stage gastric cancer, offering a minimally invasive alternative to endoscopy.
Risk and Screening
Stomach cancer begins in the stomach, and while there is no routine screening for the general population in the United States, people at high risk may undergo routine screening to check for the disease. High-risk individuals might include those with certain genetic disorders.
It is essential to consult a doctor to find out the underlying cause of any persistent or concerning symptoms. An upper endoscopy can help doctors detect stomach cancer early by identifying small, subtle changes. Doctors may also perform a physical exam, full medical history, blood chemistry tests, complete blood count, imaging scans, and biopsy to check for stomach cancer.
Remember, stomach cancer is often diagnosed late due to subtle early symptoms. Combining symptom awareness with advances in AI imaging and liquid biopsies could greatly improve early detection rates and patient outcomes. If you have any symptoms of stomach cancer, particularly if symptoms do not go away or worsen, contact a doctor immediately. Many benign conditions can cause similar symptoms, but it is always better to be safe and seek professional advice.
