Urinary Bladder
Urinary bladder cancer is a type of cancer that begins in the cells of the bladder, which is the hollow organ in the lower abdomen that stores urine. This cancer typically starts in the urothelial cells (also known as transitional cells) that line the bladder. Here's a detailed overview:
Overview
Types of Bladder Cancer
1) Urothelial carcinoma (transitional cell carcinoma):
The most common type, making up about 90% of bladder cancers. It begins in the urothelial cells that line the inside of the bladder.
2) Squamous cell carcinoma :
Healthcare providers classify thyroid cancer based on the type of cells from which the cancer grows. Types of thyroid cancer include:
This type is less common and typically results from long-term irritation or infection, such as from chronic bladder infections or the use of a catheter.
3.Adenocarcinoma :
A rare form of bladder cancer that begins in the glandular cells, which produce mucus.
Risk Factors
Several factors can increase the risk of developing bladder cancer:
- Smoking:
This is the most significant risk factor, as chemicals in tobacco smoke can damage the bladder lining.
- Age :
Most people diagnosed with bladder cancer are over the age of 55.
- Gender:
Men are more likely to develop bladder cancer than women.
- Chronic bladder inflammation:
Conditions like bladder infections, kidney stones, or the use of catheters over long periods.
- Exposure to chemicals:
Occupational exposure to certain chemicals, particularly those used in dye, rubber, and textile industries, can increase risk.
- Family history :
A family history of bladder cancer can also increase one's risk.
- Previous cancer treatments:
Radiation therapy to the pelvis or chemotherapy drugs such as cyclophosphamide may increase the risk.
Symptoms
Common signs of bladder cancer may include:
- Blood in the urine (hematuria) :
This is the most common symptom. It may cause the urine to appear bright red or dark brown.
- Painful urination:
A burning or painful sensation while urinating.
- Frequent urination :
Feeling the need to urinate more often, especially at night.
- Urgency to urinate:
A sudden, strong urge to urinate that may be hard to control.
- Lower abdominal pain :
Pain or pressure in the lower abdomen can sometimes be a sign.
Diagnosis
Bladder cancer is typically diagnosed through several tests, including:
- Urine tests:
To check for cancer cells or blood in the urine.
- Cystoscopy
A procedure in which a small camera (cystoscope) is inserted into the bladder through the urethra to look for abnormal areas.
- Biopsy
A small sample of tissue is removed during cystoscopy and examined for cancerous cells.
- Imaging Tests
Such as CT scans, MRI, or ultrasound to look for tumors in the bladder or surrounding areas.
Staging and Grading
Once diagnosed, the cancer is staged to determine how far it has spread. Bladder cancer stages range from:
- Stage 0
Cancer is only in the inner lining of the bladder (non-invasive).
- Stage I:
Cancer has spread to the deeper layers of the bladder wall.
- Stage II :
Cancer has spread to the muscles of the bladder.
- Stage III :
Cancer has spread to nearby organs or tissues.
- Stage IV :
Cancer has spread to distant parts of the body, such as the liver, lungs, or bones.
Cancer Grade
The grade of the cancer also determines how aggressive it is, with high-grade cancers being more likely to spread than low-grade ones.
Treatment
Treatment depends on the stage and grade of the cancer. Common treatment options include:
- Surgical Removal
This could be a transurethral resection (TUR) to remove superficial tumors, or more extensive surgery, such as a cystectomy (removal of the bladder).
- Chemotherapy
Often used after surgery to eliminate remaining cancer cells. It may also be given as a topical treatment or as a systemic treatment for advanced cases.
- Immunotherapy
A treatment that boosts the immune system to fight cancer, often used for early-stage bladder cancer.
- Radiation Therapy
May be used when surgery isn't an option or to shrink tumors before surgery.
- Targeted Therapy
Drugs that target specific molecules involved in the growth of cancer cells.
Prevention
While there's no surefire way to prevent bladder cancer, the following steps can reduce the risk:
-Don't Smoke
Quit if you currently do.
-Stay Hydrated
Drinking plenty of fluids, especially water, may help flush out carcinogens from the bladder.
-Minimize Exposure to Industrial Chemicals
If you work in environments that use harmful chemicals, make sure to use proper protective equipment.
Early detection and treatment are key to improving survival rates and quality of life. If you notice any symptoms like blood in your urine, it’s important to seek medical advice for a proper diagnosis.
