Gastric malignancies are among the most malignant diseases. The most common form of stomach cancer is adenocarcinoma, occurring in 85% cases, with rarer forms including lymphomas or gastrointestinal stromal tumors. The onset of cancer is associated with dietary habits, and it is observed to have a higher incidence in countries where spicier and/ or smoked foods are consumed, such as Japan, China, or Russia. Many factors, such as H. Pylori infection, stress, smoking, diet, and certain chronic conditions like gastritis, ulcer disease, and polyps, can contribute to the development of malignant disease. Initial symptoms of the disease are often nonspecific for gastric cancer, and it is usually detected in an advanced stage. Treatment and prognosis depend on the tumor stage and, of course, the preferences of the affected individual. There are various treatment methods, but only one can lead to a complete cure, and that is surgical intervention. As a member of the medical team, a nurse not only participates in diagnostic and therapeutic procedures but also provides healthcare to patients. It is essential to emphasize that each patient requires an individualized or holistic approach. The way a patient responds to the awareness of the illness and later treatment methods varies among individuals. Every malignant disease, including this one, brings numerous emotional and physical challenges. As the cornerstone of quality healthcare, a nurse should establish effective communication and a relationship of trust with the patient. This way, the patient will feel more satisfied, and healthcare will be more successful.
