Recently, I came across an article in MedicineNet.com which states that bladder cancer is a disease that occurs when cancer cells form in the tissues of the bladder. The bladder is a hollow organ in the lower abdomen that is shaped like a balloon. The bladder stores urine until it is passed out of the body. Urine is waste liquid that is made by kidneys when they clean the blood. Urine passes from the two kidneys into the bladder through two tubes called ureters. Urine goes from bladder to the outside of body through another tube called urethra. Bladder cancer has the ability to spread to different parts of body. This process of invading and spreading to other organs is called metastasis.
There are three types of bladder cancer:
1. Transitional cell carcinoma: Transitional cell carcinoma begins in cells in the innermost tissue layer of the bladder.
2. Squamous cell bladder carcinoma: Squamous cell bladder carcinoma begins in squamous cells.
3. Adenocarcinoma: Adenocarcinoma is bladder cancer type that begins in glandular (secretory) cells.
Signs and Symptoms of Bladder Cancer
Following are the symptoms of bladder cancer:
• Abdominal pain
• Blood in the urine
• Bone pains or tenderness
• Painful urination
• Urinary urgency
• Urine leakage
• Weight loss
Bladder Cancer Life Expectancy
The progonosis of bladder cancer varies with the stages of cancer and health of the patient suffering from this disease.
- Nearly 90% of people treated for superficial bladder cancer (Ta, T1, and CIS) survive for at least five years after treatment.
- Only about 5% of people with metastatic bladder cancer survive for at least two years after diagnosis.
- Recurrent cancer indicates a more aggressive type and a poor outlook for long-term survival for patients with high-stage or high-grade bladder cancer.
- Recurrent low-grade superficial bladder cancer is rarely life threatening.
