Radiation therapy for testicular tumors may have adverse effects such as radiation enteritis, bone marrow suppression, and skin and mucous membrane reactions, so it can be painful, but you will recover slowly under doctor’s supervision. The primary treatment for testicular tumor is orchiectomy. Stage I patients need to undergo radiation therapy after surgery, and the 5-year survival rate reaches 98%~100%. Stage II and III patients also need radiotherapy. During radiotherapy, there will inevitably be damage to normal tissues, and the adverse reactions mainly include radiation enteritis, bone marrow suppression, and skin and mucous membrane reactions, during which the patients will have different degrees of pain. However, they will recover slowly under the doctor’s guidance. For example, for radiation enteritis, antidiarrheal drugs, such as montelukast, can be applied symptomatically. Bone marrow suppression is mainly manifested as leukopenia, thrombocytopenia, anemia, etc., which can be treated by applying drugs such as Diyu Lianbai tablets and platelet-raising capsules. The skin at the radiotherapy place should be kept dry, avoid rubbing vigorously to reduce the skin and mucous membrane reaction, and the drugs should be reasonably applied according to the doctor’s instructions.
