Bladder Cancer

Most often, bladder cancer begins in the cells of the bladder's inner layer after cells there begin to grow abnormally. The cancer can spread to the deeper layers of the bladder, where it is more difficult to treat.

膀胱癌的症状是什么?
一个常见的症状是尿血. This can be slight, occasional and painless. Other signs include irritation when urinating or a constant/urgent need to urinate. You may feel pain in your abdomen or lower back and experience fatigue or loss of appetite. However, any of these symptoms can also be caused by less serious, non-cancerous conditions. A visit to your doctor is vital whenever you experience blood in urine.

如何诊断膀胱癌?
You'll be asked to provide a urine sample, which will be examined for the presence of cancer cells. Your doctor can also look inside your bladder by inserting a very thin, 一种叫做膀胱镜的灵活仪器. If a suspicious area is found, a sample of that area can be taken for biopsy.

Another option is a type of imaging called a CT Urogram. You may be given an IV that contains a substance that will enhance X-ray visibility of your organs. This test allows an examination of the entire area, in case any abnormalities are found in nearby parts of the body.

What are the treatments for bladder cancer?
Multiple treatments are possible, depending on the stage of your cancer and your health:

Transurethral resection of a bladder tumor, also known as TURBT: This procedure involves inserting a small instrument with a small electrified loop of wire into the bladder. The doctor will guide this instrument over the tumor, removing the affected tissue. All the removed material will be examined to determine the exact type of bladder cancer and to determine whether any additional treatment is needed.
Surgery全部或部分膀胱被切除. 如果整个膀胱被切除, there are several possible alternate methods of storing and eliminating urine. These include an external ostomy bag or several possible internal structures, including a small reservoir for collecting urine made from part of the small intestine or a combination of the large and small intestines. Your doctor will choose the best approach based on your individual situation.
Chemotherapy: Chemotherapy is meant to treat cancer cells that may have spread beyond the bladder, or to shrink the tumor before surgery so it can be removed more easily. 在转移性膀胱癌的病例中, chemotherapy may be chosen to extend and improve quality of life. It can also be given in combination with radiation. (See below)
Radiation: This can be a part of several stages of treatment. It might be used alone for people who cannot have surgery. More often, it is combined with chemotherapy, as the two treatments work together.
Immunotherapy: This treatment helps your body's immune system recognize and attack cancer cells.
Bladder preservation with Combined-Modality Therapy (CMT): This is a combination of TURBT, radiation and chemotherapy. The goal is to cure the cancer while leaving a functioning bladder in place. 然而，并不是所有的病人都是候选者. This approach is best for patients whose bladder tumors are small and appear to be completely eradicated by the TURBT.
Other therapies: Intravesical therapy involves placing medication directly into the bladder. This can be a form of chemotherapy or immunotherapy.

What are the risk factors for bladder cancer?
Bladder cancer is much more common among smokers. The cancer's incidence rises as you age; it's more common in older people. Some occupations that deal with certain chemicals (such as aromatic amines) are at higher risk. Caucasians are more likely to develop bladder cancer than are people of other races. Men are more likely than women to develop it. 既往膀胱癌病史, 或者家族史, 是否也与更高的风险有关, as is a history of frequent bladder infections.
