Adenomatoid tumors are benign tumors. 1. Men: Most often adenomatoid tumors of the testes. Symptoms may include abnormal pain in the testes and enlarged lymph nodes. 2. Women: Adenomatoid tumor of the uterus. This benign tumor is basically not cancerous, but mostly causes dysmenorrhea. This kind of tumor is slow-growing and small in size, usually not more than 5cm in diameter, and the tissue is characterized by many messy cavities in the loose or dense fibrous mesenchyme with flat to low columnar epithelial cells. Adenomatoid tumors generally grow slowly and have some probability of becoming cancerous. If the tumor is small and the symptoms are mild, and it does not affect normal life, it can be treated without surgery, with close observation and regular follow-up. If the tumor is large and has a tendency to become cancerous or seriously affects life, it is recommended to assess the severity of the disease under the guidance of a doctor and choose the appropriate method of treatment.
