Whether or not surgery is needed for lymphoid tissue hyperplasia with phlegm in the nasopharynx depends largely on the condition; if the benign hyperplasia is excessively troubling and damaging to the individual, surgery to remove the hyperplasia can be considered. If the hyperplasia is caused by nasopharyngeal cancer, radiotherapy is preferred. 1. Nasopharyngeal lymphatic hyperplasia is often caused by long-term and repeated inflammatory stimulation in the area, which is generally a benign lesion and individuals need not worry too much about it. If there is only excessive phlegm and no other discomfort, it can be followed up for observation and surgery is not necessary. If the hyperplasia is more serious and causes symptoms of breathlessness, it is recommended that the hyperplastic lesion be removed through surgery in a timely manner. Although surgery can remove such hyperplastic lesions, individuals need to treat the primary disease causing lymphatic hyperplasia in nasopharynx after surgery, or else they may easily face recurrence of the disease. 2. Nasopharyngeal cancer can also cause nasopharyngeal lymphoid hyperplasia, which should be treated in time, and radiotherapy is preferred for early stage nasopharyngeal cancer. After diagnosed with nasopharyngeal lymphoid hyperplasia, one should actively seek professional help.
