What is small B-cell malignant lymphoma?

Hello, small B cell tumor is a subtype of lymphoma, including several subtypes, but all of them are low-grade malignant lymphoma. Most of them can't be cured clinically, but the total survival time is generally long, reaching 8 years to 10 years. If the ki67 index is lower than 10%, immunohistochemistry shows that the bone marrow is not invaded, indicating that the disease develops slowly. If the patient has no conscious symptoms, he can temporarily stop treatment and observation. If I have any of the above conditions, I need treatment, which can prolong the overall survival time, and many patients can survive for a long time. Most of them will recur afterwards, and the total survival time of effective treatment is often between 15-30 years, and some people's survival time is less than 1 year. Of course, it is also possible that there will be no recurrence for decades.
