Stage 4 lymphoma cancer is curable in some patients, but terminal in others. Whether it is curable or not depends on the patient and the type of lymphoma, according to the American Cancer Society.
The 5-year survival rate for people with Hodgkin lymphoma is higher than that of people with non-Hodgkin lymphoma. Stage IV means that the cancer has spread outside the lymph nodes to other parts of the body. Age and general health often play a large factor in whether or not the cancer can be cured. It also depends on whether or not the cancer responds well to radiation or therapy.
