3. Family History and Genetic Factors
A family history of gastric cancer or inherited genetic mutations can increase susceptibility to the disease.
🔹 Genetic Conditions Linked to Gastric Cancer:
- Hereditary Diffuse Gastric Cancer (HDGC) – A rare genetic mutation that raises stomach cancer risk.
- Lynch Syndrome – A genetic disorder linked to multiple cancers, including gastric cancer.
Prevention Tip: People with a strong family history should consider genetic counseling and regular screenings.
Manifestations (Symptoms) of Gastric Cancer
Early-stage gastric cancer often does not show noticeable symptoms, but as the disease progresses, several warning signs emerge.
4. Persistent Indigestion and Stomach Discomfort
Chronic indigestion (dyspepsia) and a general sense of stomach discomfort can be early warning signs of gastric cancer.
🔹 Symptoms Include:
- A burning sensation in the upper abdomen.
- Feeling full too quickly after eating.
- Frequent bloating and belching.
When to Seek Medical Help: If indigestion persists despite dietary changes or medication, consult a doctor for further evaluation.
5. Unexplained Weight Loss and Loss of Appetite
Significant weight loss without trying is a red flag for many cancers, including gastric cancer.
🔹 Why It Happens:
- Cancer cells consume energy, leading to rapid weight loss.
- The stomach’s reduced ability to digest food results in loss of appetite.
When to Be Concerned: If you lose more than 5% of your body weight within six months without changing your diet or exercise habits.
