How long can you live with prostate cancer involving the bladder and seminal vesicle cannot be generalized, the specific survival time is closely related to the stage of the tumor. Early diagnosis and treatment of the disease is of great significance to the prognosis. The 5-year survival rate is commonly used to assess the survival of tumor patients. Generally speaking, prostate cancer involving seminal vesicles and bladder belongs to T3b and T4 stages respectively, and if left untreated, patients will die within 5 years. However, timely resection of the lesion and inguinal lymph node dissection can increase the 5-year survival rate to 57% to 100%. This is supplemented by radiation therapy and combination treatments such as anti-androgenic drugs, all of which can improve outcomes and prolong survival. Overall, once diagnosed with prostate cancer, immediate medical attention is needed. Under the guidance of the doctor, follow the standardized treatment as prescribed by the doctor and review on time in order to prolong the survival time.
