Radiation therapy uses high-dose X-rays to kill cancer cells. It can be used alone or combined with chemotherapy to treat invasive bladder cancers. In patients with advanced metastatic bladder cancer, such as cancer that has spread to the bones, radiation therapy can relieve pain and prevent complications, such as bone fractures.
The duration and dose of your radiation treatments are individualized for you based on your particular situation and goals. For invasive bladder cancer, treatment is given five days per week and for five to seven weeks. For metastatic lesions, the time required for treatment may range from one day to two weeks.
