Bladder cancer is the 7th most common cancer in the US. In 2014, there were 74,690 new cases and 15,580 deaths. Bladder cancer is more common in men than women. Risk factors include smoking, family history, occupational chemical exposure, and bladder infections. Symptoms include blood in the urine, frequent urination, and pain during urination. Diagnosis involves cystoscopy and biopsy. Staging uses CT, MRI, and PET scans to determine if the cancer has invaded the bladder wall or spread. Higher stage and grade cancers have a worse prognosis. Treatment and survival depend on the stage, with 5-year survival rates ranging from 96% for stage 0 to 5.5% for stage IV cancer

5. Signs and symptoms of
bladder cancer
• Blood in the urine (slightly
rusty to bright red in color).
• Frequent urination.
• Pain during urination.
• Lower back pain.
6. Risk Factors for Bladder
Cancer
• Using tobacco, especially smoking cigarettes.
• Having a family history of bladder cancer.
• Being exposed to certain chemicals in the
workplace.
• Past treatment with certain anticancer drugs,
such as cyclophosphamide or ifosfamide,
or radiation therapy to the pelvis.
• Drinking well water that has high levels
of arsenic.
• Having a history of bladder infections,
including bladder infections caused
by Schistosoma haematobium.
• Using urinary catheters for a long time.
8. Diagnosing Bladder Cancer
Usually a cystoscopy and biopsy will be done. There
are 3 types of cancer but most people will have
transitional cell (or urothelial cancer)
This starts in the lining of the bladder and the outlook or
prognosis is based on whether the cancer has started to
invade the wall of the bladder or the grade (how mutated
the cells have become)
9. Histology
• Urothelial Cancer > 90%
(>90% are in bladder, 8% in renal
pelvis, 2% in ureter or urethra)
• Squamous Cancer – 3%
• Adenocarcinoma – 1.4%
• Small Cell – 1%
10. Understanding the Pathology
Report
1.Type of cancer (urothelial or papillary)
2.Invasive or non-invasive
3.Grade (how mutated are the cells)
4.Biopsy (how deep) to determine the stage.
This information plus imaging studies will
determine the clinical stage
5.Final pathology report after major surgery
will determine the pathologic stage
21. Stages of Bladder Cancer
Basically how deep has the cancer invaded into the
wall of the bladder and has it spread elsewhere to
other organs or lymph nodes

of the bladder the cancer has
invaded

26. Stage 0 (Papillary Carcinoma and Carcinoma in
Situ)
Abnormal cells are found in the tissue lining the inside of the bladder
27. Stage I Bladder Cancer
Cancer has spread to the layer of connective tissue next to the inner lining of the
bladder.
28. Risk of a relapse is related to how deep the
cancer invade and how mutated the cancer
cells are. Low grade (slow growing) or High
grade (more mutated, more fast growing)
29. Stage II Bladder Cancer
Cancer has spread to the layers of muscle tissue of the bladder.
30. Stage III Bladder Cancer
Cancer has spread from the bladder to the layer of fat surrounding it. It may also have
spread to the prostate and/or seminal vesicles in men or the uterus and/or vagina in
women.
31. Stage IV Bladder Cancer
Cancer has spread from the bladder to (a) the wall of the abdomen or pelvis, (b) one
or more lymph nodes, and/or (c) other parts of the body, such as the lung, liver, or
bone.
