What Foods Should Be Eaten by Patients with Stomach Cancer?

Stomach cancer is a type of malignant tumor that develops in the stomach lining. Other types of gastric malignancies include gastrointestinal stromal tumors (GISTs) and gastric lymphomas. After surgery for stomach cancer, it is important to determine whether there is an infection with Helicobacter pylori, a type of bacteria closely linked to the development of this disease.

Maintaining a healthy diet plays a crucial role in both prevention and recovery. Patients are generally advised to consume fresh vegetables and fruits regularly, as these are rich in antioxidants and can help protect against further cellular damage. On the other hand, it is strongly recommended to avoid preserved, expired, or spoiled foods, which may contain harmful substances such as nitrates and nitrites—known contributors to cancer development.

Dietary habits are closely associated with the risk of developing stomach cancer. Long-term consumption of pickled or improperly stored foods has been identified as a potential risk factor. These foods often contain high levels of nitrosamines, which are carcinogenic compounds that can damage the stomach lining over time.

Early detection and treatment are essential for better outcomes. Stomach cancer typically begins in the mucosal layer of the stomach and is often linked to chronic H. pylori infection. Diagnosis usually involves a gastroscopy, where a small sample of tissue may be taken for biopsy. For early-stage cases, endoscopic submucosal dissection (ESD) can be performed to remove the tumor without the need for open surgery, offering a less invasive and faster recovery process.

In more advanced cases where the tumor has penetrated deeper layers of the stomach wall, surgical removal of part or all of the stomach may be necessary, often accompanied by lymph node dissection. Post-surgery, additional treatments such as chemotherapy and radiation therapy may be required. These therapies aim to eliminate any remaining cancer cells and reduce the risk of recurrence.

Adopting a balanced and nutritious diet can significantly support recovery and improve quality of life. In addition to avoiding harmful food choices, patients should focus on easily digestible meals, adequate protein intake, and staying well-hydrated. Consulting with a nutritionist can help tailor a dietary plan that supports healing and strengthens the immune system during and after treatment.
