Signs of Gastric Cancer Recurrence and Metastasis

Gastric cancer recurrence and metastasis often occur without clear warning signs, which is why regular endoscopic examinations are crucial after treatment. As a type of malignant tumor, gastric cancer carries a risk of returning even after successful surgical removal. To monitor for any possible reappearance, patients are generally advised to undergo periodic gastroscopies, especially within the first five years following surgery.

The frequency of these follow-up exams varies depending on several factors, including the type of gastric cancer—such as whether it is well-differentiated or poorly differentiated. Poorly differentiated cancers tend to have a higher likelihood of spreading, which may require more frequent monitoring through imaging tests like abdominal ultrasound or CT scans.

In addition to visual examinations, blood tests for tumor markers such as carcinoembryonic antigen (CEA) can also play a key role in detecting a recurrence or metastasis early. These biomarkers can offer valuable insight into the body's condition and may indicate cancer activity even before physical symptoms appear.

It's important to note that many patients may not experience noticeable symptoms like stomach pain, bloating, or discomfort even if the cancer has returned or spread. This asymptomatic progression makes consistent and proactive follow-up care essential for long-term survival and management.

Regular medical evaluations, therefore, remain the most effective strategy in identifying gastric cancer recurrence or metastasis at an early stage. Patients should work closely with their healthcare providers to tailor a follow-up schedule that best fits their individual diagnosis and treatment history.
