Low-grade abdominal pseudomucinous tumors can be treated by surgical resection, chemotherapy and radiotherapy. 1. Surgical resection: Through surgical resection, the tumor can be effectively treated by removing the diseased tissues, alleviating the abdominal symptoms, improving the quality of survival and prolonging the survival time. 2. Chemotherapy: Commonly used drugs include fluorouracil, cyclophosphamide, mitomycin, etc. The chemotherapeutic drugs are directly injected into the abdominal cavity, which can remove the residual tumor tissues and free cancer cells in the abdominal cavity after the operation, and irreversibly damage the cancer cells, so as to treat the disease. 3. Radiotherapy: It can damage or kill cancer cells through radioactive substances to achieve the purpose of completely treating the tumor, but it is easy to damage other normal cells and cause more damage to the body. After the appearance of low-grade abdominal pseudomucinous tumors, it is recommended to receive regular treatment in time, and not to use drugs blindly on one’s own, so as to avoid gradual aggravation of the condition, which will induce complications, endanger the life and affect the normal quality of life.
