Gastrointestinal Lymphoma is a type of cancer that affects the lymphatic system, specifically occurring in the gastrointestinal tract. It can arise in various parts of the digestive system, including the stomach and intestines. This condition is often associated with non-Hodgkin lymphoma, which is a broader category of lymphatic cancers. Symptoms of gastrointestinal lymphoma may include abdominal pain, weight loss, nausea, and changes in bowel habits. Diagnosis typically involves imaging tests, endoscopy, and biopsy to confirm the presence of cancerous cells. Treatment options may include chemotherapy, radiation therapy, or surgery, depending on the stage and location of the lymphoma.
