The extent of the disease is determinant to the lymphoma prognosis.
During stage 1, cancer is limited to a group of lymph nodes, usually in the neck or armpits, while during stage 2, there are usually more than two groups of lymph nodes affected.
Stage 3 is diagnosed when cancer has spread to a series of lymph node groups and in stage 4, cancer has already spread to organs and bone marrow, in addition to the lymphatic system.
In addition to the stage, patients are diagnosed according to the symptoms as A or B lymphoma.
While A means that there are no symptoms in addition to swollen lymph nodes, B includes symptoms such as weight loss, fever and night sweats.
