Bladder cancer is the development of cancer in the bladder and as a result formation of tumor in the bladder due to accumulation of cancerous cells. Bladder cancer prognosis depends on the stage of the cancer, chances of recurrence and the type of bladder cancer.
Major types of bladder cancers are transitional cell carcinoma in which the cells in which cancer begins in the inner lining of the bladder, adenocarcinoma which affects the mucus secreting glands of the bladder and squamous cell carcinoma which is caused due to irritation and infection in the bladder.
The major risk factors of bladder cancer are increasing age, smoking, and exposure to certain chemicals, heredity, medications and other diseases. Also men are more prone to bladder cancer then women.
Bladder Cancer Prognosis:
The bladder cancer prognosis is more favorable if the disease is diagnosed much earlier. For that it is important to know the symptoms of the disease so that you seek medical help at an earlier stage. Major symptoms of bladder cancer are blood in urine, pain while urination, polyuria, pelvic and back pain.
The course and outcome of the bladder cancer mostly depends on the stage of cancer when it is diagnosed. Bladder cancer may recur so follow up checking is very important for several years regularly after every 3-5 months. Other factors which affect the prognosis of bladder cancer are number and size of the tumor and certain mutations in the genes of the person.
- Around 9 out of 10 patients who were treated for Ta cancer that is superficial cancer survive for at least 5years.
- In case of superficial cancer the chances of recurrence is 15% in one year and 32% in five years.
- The chances of progression of tumor in the deeper layers of bladder are less than 1% in case of superficial cancer.
- High grade superficial cancer is associated with extensive areas of carcinoma in situ. Multiple and large tumors have an recurrence rate of 60% in 1 year which increases to 80% in five years.
- These tumors have greater tendency to spread to other parts and penetrate in the inner layers of bladder in comparison to tumors of superficial cancer. There is a 15% chance that tumor will penetrate within one year and 45% within 5 years.
- The five year survival rate of localized cancer is 94%, 48 % for regional cancer and 6% for distant cancer.
- The doctor who is familiar with the condition of the person can discuss about the bladder cancer prognosis of the person and make him understand what to expect. However, doctors cannot tell the exact outcome and what will happen after several years.
Prognosis may vary with the age of the person and the overall health. Bladder cancer prognosis may change if the cancer progresses or if treatment is successful. Each patient is different from the other and it is not possible to predict anything exactly. All the above stats are estimations and you can have a totally different prognosis.
