Urinary bladder cancer is a type of cancer that begins in the cells that line the bladder. It is the fourth most common cancer in men and the ninth most common cancer in women. There are several different types of bladder cancer, each with different characteristics and treatment options.
Causes of Urinary Bladder Cancer
The exact causes of urinary bladder cancer are not yet fully understood, but certain factors may increase the risk of developing the disease. These factors include:
- Smoking: Smoking is the most significant risk factor for bladder cancer. In fact, smokers are two to three times more likely to develop bladder cancer than non-smokers.
- Exposure to certain chemicals: Exposure to chemicals such as benzene, aromatic amines, and polycyclic aromatic hydrocarbons may increase the risk of developing bladder cancer.
- Chronic bladder inflammation: Chronic bladder inflammation caused by conditions such as interstitial cystitis or repeated bladder infections may increase the risk of developing bladder cancer.
- Age and gender: Bladder cancer is more common in men and in older individuals.
Symptoms of Urinary Bladder Cancer
The symptoms of urinary bladder cancer may vary depending on the type and stage of the cancer. Some common symptoms include:
- Blood in the urine: This is the most common symptom of bladder cancer. Blood may appear as pink, red, or brown in color.
- Painful urination: Bladder cancer may cause pain or discomfort during urination.
- Frequent urination: Bladder cancer may cause an increased need to urinate, even if there is little urine in the bladder.
- Urinary urgency: Bladder cancer may cause a sudden and urgent need to urinate.
- Pain in the lower back or abdomen: Bladder cancer that has spread may cause pain in the lower back or abdomen.
Diagnosis of Urinary Bladder Cancer
If a patient experiences symptoms of urinary bladder cancer, the doctor may recommend several diagnostic tests to determine the underlying cause of the symptoms. These tests may include:
- Physical exam: The doctor will perform a physical exam to check for any signs of bladder cancer.
- Urine tests: The doctor may order a urine test to check for blood or abnormal cells in the urine.
- Cystoscopy: A cystoscopy is a procedure that involves inserting a small tube with a camera through the urethra and into the bladder to examine the bladder lining for signs of cancer.
- Biopsy: If abnormal cells are found during a cystoscopy, the doctor may perform a biopsy, which involves removing a small sample of tissue for examination under a microscope.
- Imaging tests: Imaging tests such as CT scans or MRI may be ordered to determine the extent of the cancer and whether it has spread to other parts of the body.
Treatment of Urinary Bladder Cancer
The treatment of urinary bladder cancer may vary depending on the type and stage of the cancer, as well as the patient’s overall health and other factors. Some common treatment options include:
- Surgery: Surgery is often the primary treatment for bladder cancer. The goal of surgery is to remove the cancerous tissue from the bladder. In some cases, the entire bladder may need to be removed (cystectomy). If the bladder is removed, the surgeon will create a new way for urine to leave the body, such as an ostomy or a new bladder made from a segment of the intestine.
- Chemotherapy: Chemotherapy involves using drugs to kill cancer cells. Chemotherapy may be used before or after surgery, or as a standalone treatment. Systemic chemotherapy is given through a vein and travels throughout the body to kill cancer cells wherever they may be. In some cases, chemotherapy may be given directly into the bladder through a catheter.
- Immunotherapy: Immunotherapy involves using drugs to boost the body’s immune system to fight cancer. Immunotherapy may be used to treat advanced bladder cancer that has not responded to other treatments. The most common type of immunotherapy for bladder cancer is called Bacillus Calmette-Guerin (BCG) therapy. BCG is a weakened form of the bacteria that causes tuberculosis. When given directly into the bladder, it stimulates the immune system to attack and destroy cancer cells.
- Radiation therapy: Radiation therapy uses high-energy rays to kill cancer cells. It may be used alone or in combination with other treatments. Radiation therapy is often used for patients who are not healthy enough for surgery or who have a tumor that cannot be completely removed.
- Targeted therapy: Targeted therapy involves using drugs that target specific proteins or genes that are involved in the growth and spread of cancer cells. Targeted therapy may be used to treat advanced bladder cancer that has not responded to other treatments.
- Bladder-sparing approaches: Some patients may be candidates for bladder-sparing approaches, such as transurethral resection of bladder tumor (TURBT) and radiation therapy. This approach involves removing the tumor from the bladder using a scope inserted through the urethra, followed by radiation therapy to kill any remaining cancer cells. This approach may be used for patients with early-stage bladder cancer.
After treatment, patients will need to undergo follow-up exams and tests to monitor for any recurrence of the cancer. These tests may include imaging tests, urine tests, and cystoscopy. Patients may also need to make lifestyle changes, such as quitting smoking and maintaining a healthy diet and exercise routine, to reduce the risk of recurrence.
In conclusion, urinary bladder cancer is a serious condition that requires prompt diagnosis and treatment. The most common treatment options include surgery, chemotherapy, immunotherapy, radiation therapy, and targeted therapy. The treatment plan will depend on the stage and aggressiveness of the cancer, as well as the overall health of the patient. After treatment, patients will need to undergo regular follow-up exams and tests to monitor for any recurrence of the cancer.
