Testicular leukemia needs to be decided according to the specific conditions (such as unilateral testicular involvement and bilateral testicular involvement) whether to be excised or not, if the doctor really needs to be excised but does not take the excision, it may lead to testicular necrosis and other consequences. 1. Bilateral testicular leukemia patients can be treated with bilateral testicular radiation therapy. Bilateral patients generally do not use excision treatment because if only one side of the testis with severe lesions is excised, it cannot achieve the therapeutic purpose, and if both sides are excised, it will have a serious impact on the sexual development of the children who have survived for a long period of time. 2. Unilateral resection is feasible, especially when one side of the testis is seriously enlarged, surgical resection of the testis on the diseased side is the most thorough way to eliminate the hidden danger, and testicular radiation therapy is also available. If the testis is not removed, severe unilateral lesions may cause necrosis. Testicular leukemia is caused by leukemia cells invading the testis. Early on, there may be no manifestations of the disease, and it is only detected during a biopsy of the testicular tissue. Patients who have developed testicular leukemia at the time of initial diagnosis are usually treated first with induction therapy to complete remission and continued with consolidation, extramedullary leukemia control, and early intensive therapy. Medications include methotrexate, among others. Specific diagnosis and treatment should be directed by a physician.
