Gastric lymphoma is a relatively rare form of cancer that affects the lymphatic tissue in the stomach. It is classified as a type of non-Hodgkin lymphoma, which originates in the lymphocytes, a type of white blood cell. The prevalence of gastric lymphoma varies depending on geographic location and population demographics.
Studies have shown that gastric lymphoma accounts for approximately 1-5% of all gastric malignancies. However, it is important to note that the prevalence of gastric lymphoma has been declining over the years, possibly due to improved diagnostic techniques and treatment options.
Several factors can contribute to the development of gastric lymphoma, including chronic inflammation of the stomach lining, infection with Helicobacter pylori bacteria, and certain genetic abnormalities. It is more commonly diagnosed in individuals over the age of 60, with a slightly higher incidence in males.
Early detection and accurate diagnosis of gastric lymphoma are crucial for effective treatment. Symptoms may include abdominal pain, nausea, vomiting, weight loss, and gastrointestinal bleeding. If you experience any of these symptoms, it is important to consult a healthcare professional for further evaluation.
