Stomach cancer: how to recognize the first signs and protect yourself

Common signs:

  • Unmotivated weight loss – 5–7 kg in a few months.

  • Constant fatigue, lack of energy, apathy.

  • Anemia – paleness, dizziness, weakness.

  • Dark or black stools – a possible sign of internal bleeding.

Important: These symptoms can also occur with other diseases such as gastritis or ulcers, but you should not ignore them. Timely consultation with a doctor is the surest way to rule out a serious diagnosis.

3. Diagnostics – how to check the stomach

If you have suspicions, the doctor may recommend the following tests:

Gastroscopy (FGDS)

  • Allows direct viewing of the gastric mucosa with an endoscope.

  • If necessary, a biopsy is taken for laboratory analysis.

  • Recommended frequency: after the age of 40 – once every 2-3 years, and in case of chronic diseases – once a year.

Test for Helicobacter pylori

  • It is performed by testing blood, exhaled air, or a fecal sample.

  • If the bacteria is detected, treatment with antibiotics and preparations to restore the mucosa is prescribed.

Abdominal ultrasound and computed tomography (CT) scan

  • They provide information about the possible spread of the disease and the presence of metastases.

Tumor marker analysis (CA 72-4, CEA)

  • It does not replace gastroscopy, but can be an additional guide to the condition of the body.

4. How to reduce the risk – effective prevention

Nutrition

  • Limit your consumption of smoked, salty, and spicy foods.

  • Increase your intake of vegetables, fruits, and green spices – they contain antioxidants that protect cells.

  • Avoid products with nitrates – sausages, canned goods, and convenience foods.
