What Happens
Bladder cancer
is the rapid, uncontrolled growth of abnormal cells in the bladder. Cancer
usually begins in the lining of the bladder. 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 doctor finds out 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 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 about 74% of bladder cancers are diagnosed
at this early stage.2 Survival 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.
