Patients with lymphoma commonly exhibit symptoms such as fever, clinically referred to as B symptoms. Some patients may also experience additional B symptoms such as fatigue, sweating, or weight loss. Patients displaying these B symptoms generally have a poorer prognosis. Furthermore, lymphoma patients typically experience fever more frequently in the afternoon or evening, usually presenting with a low-grade fever. If the condition of a lymphoma patient is not controlled, their fever symptoms will recur repeatedly. Only when the condition is under control will there be an alleviation of fever symptoms. Anti-inflammatory drugs are not effective in these cases.
