Definition: Bladder cancer bladder cancer s usually start from the cells lining the bladder (called transitional cells).

The following tumours are classified based on the way they grow:
Papillary tumours have a wart-like appearance and are attached to a stalk.
Nonpapillary (sessile) tumours are flat. They are much less common. However, they are more invasive and have a worse outcome.

Ninety percent of bladder cancers are transitional cell carcinoma. The other 10% are squamous cell carcinoma, adenocarcinoma, sarcoma, small cell carcinoma, and secondary deposits from cancers elsewhere in the body.

Symptoms of bladder cancer can include:
1. Abdominal pain
2. Blood in the urine
3. Bone pain or tenderness if the cancer spreads to the bone
4. Fatigue
5. Painful urination
6. Urinary frequency
7. Urinary urgency
