14 NCCN Guidelines for Patients ® : Follicular Lymphoma, Grade 1–2, 2017 1 Follicular lymphoma basics Review Review The lymphatic system consists of lymph and a network of vessels and organs. It helps kill germs in the body and transports fluids to the bloodstream. Lymphomas are cancers that start in lymphocytes within the lymphatic system. Follicular lymphoma starts in B-cells that are from germinal centers found within lymphatic organs. Follicular lymphoma is often a slow-growing cancer. It may take years before signs and symptoms appear. Incisional or excisional biopsy is needed to diagnose follicular lymphoma. The biopsy tissue should be tested by a hematopathologist. The hematopathologist will perform a number of tests that assess for cell type, surface proteins, and maybe genetics.
