Follicular pharyngitis is usually not cancerous because the follicles in follicular pharyngitis are mostly lymphoid follicles, formed by a large amount of lymphoid tissue aggregation, and are often not cancerous. Although lymphoid tissue in the pharynx can also become cancerous, it is mostly a primary cancer, which is not related to the disease and is mainly related to long-term stimulation by tobacco and alcohol, personal autoimmunity and genetic mutations.
