Final answer:
Reed-Sternberg cells are a hallmark of Hodgkin lymphoma and their presence can lead to symptoms like fatigue and swollen lymph nodes. Early diagnosis and treatment are essential for a good prognosis.
Step-by-step explanation:
Reed-Sternberg cells are typically present in Hodgkin lymphoma, a type of lymphoma that can cause symptoms such as fatigue, swollen lymph nodes, loss of appetite, weight loss, fever, and night sweats. These cells are distinctive, large, and abnormal lymphocytes that may contain more than one nucleus. Hodgkin lymphoma is distinguishable from non-Hodgkin lymphoma by the presence of Reed-Sternberg cells. It is crucial for the disease to be diagnosed early and treated promptly since, with proper treatment, many patients have a strong chance of cure.
