Type B lymphoma is generally malignant, only the type differs and the progression differs. type B lymphoma is one type of lymphoma, and lymphomas are generally malignant, including type B lymphoma, but some type B lymphomas may not progress for a long time and are called inert lymphomas, which eventually turn to belong to the category of malignant tumors despite their biological behavior is benign. For example, the small B-cell lymphomas such as condyloma, follicular lymphoma, and mucosa-associated lymphoma have low grade early lesions and progress more slowly. Lymphomas such as large B-cell or diffuse large B-cell lymphoma and gray zone Burkitt’s lymphoma progress more rapidly and are intermediate to high-grade lymphomas. Low-grade lymphomas, despite being inert tumors, can eventually turn into a malignant process if left untreated or not treated aggressively.
