The symptoms of lymphoma mostly present as painless enlarged superficial lymph nodes, which are common clinical manifestations. Additionally, there may be enlargement of the liver and spleen, with multiple organs throughout the body possibly affected. In advanced stages, patients may experience invasion of the bone marrow. There are also special types of extranodal lymphomas which exhibit specific symptoms. For instance, lymphomas originating in the stomach may present with upper abdominal masses, or symptoms like anemia, weight loss, black stools, and even upper abdominal pain, nausea, and vomiting related to the gastrointestinal tract. If the lymphoma originates in the nasal cavity, known as NK/T-cell lymphoma, symptoms may include tinnitus, nasal congestion, runny nose, and nosebleeds, among others. Some lymphoma patients may also experience fever, generalized weakness, weight loss, collectively referred to as B symptoms.
