In the early stages, stomach cancer can present with almost no symptoms, but warnings like a sensation of food sticking, persistent nausea, or rapid fullness should not be ignored. These signs can signal a problem that may worsen if left unattended. The information below reflects insights shared by Doctor Oleg Kit, an oncologist with Doctor of Medical Sciences, discussing this portal.
Stomach cancer may remain asymptomatic in its initial phases, which is why many cases are identified only after the disease has progressed. A portion of patients may overlook early warning signs. Common sensations such as the quick onset of fullness after meals or feeling that food is blocked can precede more troubling symptoms, including severe nausea and vomiting. When such signs appear, a medical evaluation is warranted. While these symptoms can arise from noncancerous gastrointestinal issues, it is essential to rule out serious conditions first.
Endoscopic screening with upper GI endoscopy, often referred to as FGDS in some regions, can detect stomach cancer early. This screening is generally recommended to start from age 45, with routine annual examinations advised for individuals over 60. If there is a close family history of stomach cancer, regular FGDS screening may be considered earlier, potentially starting before age 45, based on a clinician’s assessment.
The portal outlines several risk factors associated with stomach cancer. These include infection with Helicobacter pylori, higher body weight and reduced physical activity, insufficient intake of fresh vegetables and fruit, blood type A (II), and high nitrate consumption from foods such as processed and smoked products. Lifestyle and dietary patterns can influence risk, underscoring the value of a balanced, plant-rich diet alongside regular medical checkups.
Earlier research has suggested that dietary choices can impact cancer risk. For instance, some studies have indicated that market-focused findings point to potential protective effects from consuming certain vegetables, though results can vary. It remains prudent to discuss specific dietary strategies with a healthcare provider, particularly for individuals at elevated risk due to family history or other factors.
