bladder is an organ in the body where urine is stored before being expelled through urination. There are several different types of bladder cancer:
* transitional cell carcinoma (cancer that begins in cells that normally form the inner lining of the bladder) are the most common.
* Squamous cell carcinoma is the kind that begins in thin, flat cells.
* Adenocarcinoma begins in the cells that make and release mucus and other fluids.
cells that cause squamous cell carcinoma and adenocarcinoma growing in the inner lining of the bladder and cause chronic irritation and inflammation.
, which is cancer in the cells lining the bladder is called superficial bladder cancer. Your doctor may be called carcinoma in situ. This type of bladder cancer returned many times, even after treatment. When the disease returned, it is usually as another superficial bladder cancer.
Cancer that begins as a superficial tumor may grow through the lining of the bladder wall. When this happens, it is known as "invasive" one. It may grow through the bladder wall. It can also grow into nearby organs like the uterus or vagina in women or prostate in men. This type of invasive carcinoma can also invade the walls of the abdomen.
When cancer spreads from one organ to another organ in the body, a new tumor will have the same cell types as the original tumor. That is, if the cancer cells that originated in the bladder to invade the lungs, the cancer cells in the lungs are actually bladder stanice.Tumora in the lungs will be treated as if it was bladder cancer, not as lung cancer. Sometimes doctors call the new tumor "distant" disease.
