Follicular lymphoma is a type of non-Hodgkin lymphoma, which is a cancer that originates in the lymphatic system. It arises from B-cells, a type of white blood cell, and is characterized by the growth of abnormal lymphoid follicles. This condition typically progresses slowly and may not cause symptoms in its early stages, making it challenging to detect. Patients with follicular lymphoma may experience swollen lymph nodes, fatigue, or weight loss as the disease advances. Treatment options vary and can include chemotherapy, radiation therapy, or targeted therapies, depending on the stage and symptoms of the disease. Regular monitoring is essential for managing this condition.
