There is no inflammation but only nodules can be left untreated if there are no accompanying symptoms, and can also be treated with medication or surgical excision, freezing, laser and other methods. If the nodules are small and do not cause obvious swelling or pain, they can be left untreated. Under the guidance of the doctor, medication can also be taken to improve local blood circulation and promote self-absorption of small nodules. If the size of the nodule is large, it can be removed through surgical excision, freezing, laser and other methods. Benign nodules usually do not recur after removal, but malignant nodules may recur. Malignant nodules need to be treated with radiotherapy and chemotherapy after removal of the nodule. Patients need to actively cooperate with doctors to prevent further aggravation of the disease.
