If a doctor removes all the cancer that can be seen at the time of the operation, a patient may be given chemotherapy after surgery to kill any cancer cells that are left. Chemotherapy given after an operation to a person who has no cancer cells that can be seen is called adjuvant chemotherapy. For bladder cancer, chemotherapy is sometimes given before surgery to try to improve results or to preserve the bladder. Chemotherapy given in this manner is called neoadjuvant chemotherapy. Neoadjuvant chemotherapy is being carefully studied in a clinical trial sponsored by the National Cancer Institute.
Biological therapy tries to get the body to fight cancer.
It uses materials made by the body or made in a laboratory to boost, direct, or restore the body's natural defenses against disease. Photodynamic therapy is a new type of treatment that uses special drugs and light to kill cancer cells. A drug that makes cancer cells more sensitive to light is put into the bladder, and a special light is used to shine on the bladder. This therapy is being studied for early stages of bladder cancer. Treatment by Stage Treatment of cancer of the bladder depends on the stage of the disease, the type of disease, and the patient's age and overall condition.
