What Happens
Bladder cancer is the rapid, uncontrolled growth of
abnormal cells in the bladder. Cancer usually begins in the lining of the
bladder (superficial bladder cancer). The cancerous cells may grow through the
lining into the muscular wall of the bladder. Invasive bladder cancer may
spread to
lymph nodes, other organs in the pelvis (causing
problems with kidney and bowel function), or other organs in the body, such as
the liver and lungs.
Bladder cancer is classified by
stage
and grade. The stage is determined by the
cancer
growth in the bladder wall
and how far it has spread to nearby tissues
and other organs, such as the lungs, the liver, or the bones. The grade of
bladder cancer is determined by how the cancer cells look in comparison with
normal bladder cells.
Your health professional determines the stage and grade of your
bladder cancer by gathering information from a variety of tests, including
blood tests, urine tests,
biopsies,
bone scans,
X-rays, and
CT scans. The stage and grade of your cancer are
important factors in selecting the treatment option that is right for you.
Bladder cancer is usually curable if it is diagnosed while the
cancer is still contained in the bladder, and up to 80% of bladder cancers are
diagnosed at this early stage.3Survival rates decrease as the stage of cancer becomes
more advanced, as the cancer cells become more abnormal (grade), and when the
cancer involves lymph nodes or other body organs.1
