Your doctor will ask you about your smoking history and the kinds of jobs you have held that may have exposed you to cancer-causing agents. You will also be asked about your medical history such as medications used, history of other types of cancer, and past treatments with radiation therapy . These areas of your history may help provide clues regarding your personal risk of developing bladder cancer.
You will also be asked questions about your current symptoms:
A physical exam will be done. Special attention will be paid to the abdominal exam, checking to see if any mass can be felt and verifying any areas of tenderness or pain. Depending on your symptoms, your doctor may also do a vaginal, pelvic, or rectal exam. Your abdomen, pelvis, and rectal area will be manually probed to determine whether there are masses that can be felt. These examinations may be a bit uncomfortable, but should not be painful.
Urine tests will be done to check for the presence of blood, infection, or other abnormal cells. The cytology of urine cells will also be evaluated. Cytology is the study of cells. The cytology of cancer cells differs from normal cells.
The unique cellular features seen on biopsy samples are used to determine the diagnosis and assess the prognosis of a cancer. Cytology testing of the urine will look for the presence of cancer cells and also help determine if the urine contains abnormal cells from the kidney or bladder, which might indicate cancer.
Your doctor may order imaging studies to verify the presence of a tumor in your bladder and to see if the tumor is causing any obstruction of the kidneys. Imaging studies that may be done include:
The doctor may remove a small sample of tissue, called a biopsy , from your bladder to test for cancer cells. A cystoscope will be inserted through your urethra and into your bladder. A cystoscope is a very small instrument with a long, flexible, and slender tube through which the doctor can see. This tube has a small light at the end to help view the interior of the bladder. During this procedure, the inside of your bladder can be examined and photographed.
Instruments can be passed through the cystoscope into the bladder to remove tiny samples of tissue called biopsies. These biopsies will be sent to the laboratory to check for the presence of cancer. Biopsy studies determine whether the tumor is confined to a small amount of tissue on a stalk (papillary), or whether it has invaded the wall of the bladder (non-papillary). More invasive types of bladder cancer have a higher rate of metastasis, which means they are more likely to spread elsewhere in the body.
If your doctor finds a suspicious tumor outside the bladder involving a lymph node, for example, a needle biopsy may be ordered. During this test, a small needle, guided by x-ray or other imaging techniques, is inserted into the lymph node. A sample of tissue is removed and examined under a microscope for the presence of cancer cells.
In many cases, it is important to surgically remove the cancer from the bladder. This may involve removing all or part of the bladder, including the wall. Or, it may involve removing only the cancer itself from the inside of the bladder, leaving the bladder otherwise intact. In such a situation, the cystocope is used to perform a transurethral resection of the tumor. Transurethral means that it is not performed with an open abdominal incision. Instead, instruments are passed up the urethra and into the bladder, and the tumor is removed through the urethra.
Results from this procedure will help to determine if your tumor is localized or whether it has begun to invade the bladder wall. While information from the removal of your bladder tumor helps determine an appropriate treatment plan, it is also an important step in your treatment. If transurethral resection shows that the tumor has invaded the bladder wall, more extensive treatment can be planned.
Staging is the process by which physicians determine the extent of the disease or how far cancer has spread. This information and other factors, like the age and type of cancer cells, determine the prognosis. Staging is important for making treatment decisions. Several features of the cancer are used to arrive at a staging classification. The most common features are the size of the original tumor, extent of local invasion, and spread to the local lymphatic and distant sites. Low staging classifications (1-2) imply a favorable outcome, and high staging classifications (3-4) imply an unfavorable outcome.
Staging bladder cancer involves a variety of diagnostic radiologic techniques, such as CT scan and MRI. Grading is a microscopic description of the cancer cells, how they look under the microscope, and the percentage of cells that appear to divide. Grading the tumor cells is important, particularly for certain types of tumor, like brain tumors. Faster growing, more invasive, more disorganized cells are assigned a higher and more serious tumor grade.
Staging tests include:
A simple staging system for bladder cancer is as follows:

Prognosis is a forecast of the probable course and/or outcome of a disease or condition. Prognosis is most often expressed as the percentage of patients who are expected to survive over five or ten years. Cancer prognosis is a inexact process. This is because the predictions are based on the experience of large groups of patients suffering from cancers at various stages. Using this information to predict the future of an individual patient is always imperfect and often flawed, but it is the only method available.
