What is bladder cancer?
Bladder cancer occurs in the tissues of the bladder, which is the organ in the body that holds urine. According to the National Institutes of Health, approximately 45,000 men and 17,000 women per year are diagnosed with the disease.
Types of bladder cancer
There are three types of bladder cancer:
Transitional cell carcinoma
Transitional cell carcinoma is the most common type of bladder cancer. It begins in the transitional cells in the inner layer of the bladder. Transitional cells are cells that change shape without becoming damaged when the tissue is stretched.
Squamous cell carcinoma
Squamous cell carcinoma is a rare cancer in the United States. It begins when thin, flat squamous cells form in the bladder after a long-term infection or irritation in the bladder.
Adenocarcinoma
Adenocarcinoma is also a rare cancer in the United States. It begins when glandular cells form in the bladder after long-term bladder irritation and inflammation. Glandular cells are what make up the mucus-secreting glands in the body.
What are the symptoms of bladder cancer?
Many people with bladder cancer can have blood in their urine but no pain while urinating. There are a number of symptoms that might indicate bladder cancer like fatigue, weight loss, and bone tenderness, and these can indicate more advanced disease. You should pay particular attention to the following symptoms:
- blood in the urine
- painful urination
- frequent urination
- urgent urination
- urinary incontinence
- pain in the abdominal area
- pain in the lower back
What causes bladder cancer?
The exact cause of bladder cancer is unknown. It occurs when abnormal cells grow and multiply quickly and uncontrollably, and invade other tissues.
