The survival period of non-Hodgkin’s lymphoma cannot be generalized, and the data show that there are still differences in the survival period, which is closely related to pathological typing, clinical stage, whether active treatment, physical condition and so on. Generally speaking, patients with non-Hodgkin’s lymphoma stage Ⅰ, Ⅱ and Ⅲ, through timely and effective treatment, patients can get a longer survival period, and can survive with tumor for 10 years or even 20 years. So early detection and early treatment is the key to improve the cure rate of non-Hodgkin’s lymphoma.
