Bladder cancer originates in the tissues of the bladder, the organ responsible for storing urine. It is among the most common types of cancer, affecting thousands of individuals worldwide each year. The majority of bladder cancers are diagnosed at an early stage when the cancer is highly treatable. However, even early-stage bladder cancer can recur after treatment. Therefore, patients typically require follow-up tests for years after treatment to look for bladder cancer recurrence. Bladder cancer’s signs and symptoms may include blood in the urine (hematuria), which may be visible to the naked eye or microscopic, and changes in bladder habits or symptoms of irritation.
Causes
Bladder cancer symptoms can vary but commonly include:
- Blood in Urine (Hematuria): This is the most common symptom, which might appear bright red or cola-colored. Sometimes, the blood is not visible without a microscope.
- Frequent Urination: Experiencing a higher than normal frequency of urination.
- Painful Urination: Experiencing pain or burning sensations during urination.
- Pelvic Pain: Chronic pain in the pelvic area.
- Back Pain: Pain in the lower back, often on one side.
It’s important to note that these symptoms can also be caused by conditions other than bladder cancer, such as infections, benign tumors, bladder stones, or other urinary tract conditions. Therefore, it’s crucial to consult a healthcare provider for an accurate diagnosis if any of these symptoms are present. Early detection and treatment of bladder cancer can significantly improve the likelihood of successful outcomes.

Diagnostics
Diagnosing bladder cancer typically involves a series of tests and procedures to confirm the presence of cancer cells and determine the extent of the disease. Key diagnostic steps include:
- Urine Tests: Checking for blood, cancer cells, or other markers of cancer in a urine sample.
- Cystoscopy: A procedure that involves inserting a cystoscope through the urethra into the bladder to visually inspect the bladder wall for tumors or abnormal areas.
- Biopsy (Transurethral Resection of Bladder Tumor, TURBT): During cystoscopy, a tool is used to remove cells or tissue samples from the bladder for analysis under a microscope. TURBT can also serve as a treatment to remove cancerous tissue.
- Imaging Tests: Ultrasound, CT scans, MRI scans, and intravenous pyelogram (IVP) can help evaluate the bladder and check for the spread of cancer to other areas.
Treatment
The treatment plan for bladder cancer depends on the cancer’s stage, grade, and type, as well as the patient’s overall health and treatment preferences. Treatment options include:
- Surgery:
- Transurethral Resection of Bladder Tumor (TURBT): Used for early-stage cancers to remove tumors from the bladder wall.
- Cystectomy: Partial or radical removal of the bladder. In radical cystectomy, nearby lymph nodes, part of the urethra, and surrounding tissues may also be removed. For men, the prostate might be removed, and for women, the uterus, ovaries, and part of the vagina might be removed.
- Urinary Diversion: If the entire bladder is removed, creating a new way for urine to exit the body is necessary. Options include an ileal conduit or a neobladder.
- Intravesical Therapy: For early-stage or superficial bladder cancer, treatment involves placing drugs directly into the bladder through a catheter. The most common intravesical therapy is Bacillus Calmette-Guérin (BCG), which stimulates the immune system to attack bladder cancer cells. Chemotherapy can also be used intravesically.
- Chemotherapy: Can be used before surgery (neoadjuvant) to shrink tumors or after surgery (adjuvant) to kill any remaining cancer cells. Systemic chemotherapy is also used for advanced bladder cancer that has spread beyond the bladder.
- Radiation Therapy: Often used in combination with chemotherapy for treating bladder cancer, especially if surgery isn’t an option. It can also be used as palliative care to relieve symptoms in advanced cases.
- Immunotherapy: Uses the body’s immune system to fight cancer. For bladder cancer, immune checkpoint inhibitors such as pembrolizumab or atezolizumab may be used, especially in cases where the cancer has spread or if BCG therapy hasn’t been effective.
- Targeted Therapy: Targets specific genes, proteins, or the tissue environment that contributes to cancer growth and survival. This type of treatment is used for bladder cancer that has specific genetic changes.
Treatment for bladder cancer often involves a combination of these methods, tailored to the individual’s specific situation. Advances in research are continually improving the options and effectiveness of bladder cancer treatments, offering hope for better outcomes and quality of life for patients.
Prevention
Preventing bladder cancer involves reducing exposure to risk factors when possible. While not all cases can be prevented, especially those linked to genetic predisposition, the following measures may help lower the risk:
- Avoid Smoking: Tobacco use is a major risk factor for bladder cancer. Quitting smoking can significantly reduce your risk.
- Limit Exposure to Chemicals: Occupational exposure to certain chemicals used in the dye, rubber, leather, and textile industries can increase bladder cancer risk. Following safety guidelines and using protective equipment can help minimize exposure.
- Stay Hydrated: Drinking plenty of fluids, especially water, may reduce the concentration of harmful substances in your urine and help flush them through your bladder more quickly.
- Consume a Healthy Diet: A diet rich in fruits and vegetables may help lower the risk of bladder cancer.
Complications
Treatment for bladder cancer, particularly for more advanced stages, can lead to several complications, including:
- Urinary Incontinence: Surgical procedures and treatments affecting the bladder can result in temporary or permanent loss of bladder control.
- Changes in Urinary Function: Depending on the type of treatment or surgery, patients may experience changes in how they urinate, such as needing a urostomy bag after bladder removal.
- Sexual Health Issues: Treatments, especially surgery, can affect sexual function in both men and women.
- Emotional and Psychological Impact: The diagnosis and treatment of bladder cancer can have significant emotional and psychological effects, necessitating support and counseling.
Conclusion
Bladder cancer presents a significant health challenge, but advancements in detection and treatment have improved outcomes for many patients. Understanding the risk factors and early symptoms of bladder cancer is crucial for early diagnosis and effective treatment. Although some risk factors like genetic predisposition cannot be changed, lifestyle adjustments can help reduce the overall risk. For those diagnosed with bladder cancer, a range of treatments, including surgery, intravesical therapy, chemotherapy, radiation therapy, immunotherapy, and targeted therapy, offers hope for successful management of the disease. Ongoing research continues to explore new treatment options, aiming to enhance the quality of life and survival rates for bladder cancer patients. The journey through bladder cancer diagnosis and treatment underscores the importance of regular medical check-ups, patient education, and support networks in managing the disease and its impacts on patients’ lives.
