About Distal Urethral Cancer
Distal urethral cancer is a type of urethral cancer that affects only the lower part of the urethra. The exact causes of urethral cancer are not fully understood.
Non-modifiable risk factors (factors that a person cannot change or control) for urethral cancer include:
- Age: Older adults are more likely to develop this type of cancer.
- Gender: Men are more commonly affected than women.
- Race: Black individuals have a higher risk compared to white individuals.
- Personal history: Having a history of bladder cancer may increase the risk.
Modifiable risk factors (factors a person potentially can change or control) for urethral cancer include:
- Chronic inflammation: Conditions that cause chronic inflammation in the urethra, such as sexually transmitted diseases (STDs) and frequent urinary tract infections (UTIs), can increase the risk.
- HPV infection: Certain strains of human papillomavirus (HPV), a sexually transmitted infection, have been linked to urethral cancer.
- Urethral abnormalities: Urethral strictures in males and urethral masses or outpouchings in females can increase the risk.
- Smoking cigarettes.
- Long-term use of urinary catheters (tubes inserted through the urethra to drain the bladder)
It's important to note that while these risk factors may increase the likelihood of developing urethral cancer, they do not guarantee its development. Regular check-ups with a healthcare professional can help monitor and manage these risks.
Distal urethral cancer can be challenging to detect in its early stages, as symptoms may not be noticeable until the cancer has progressed. However, here are the most common early symptoms:
- Pain or bleeding during urination
- Changes in urination: urinating more than usual, weak urination stream (low flow or dribbling)
- Discharge for fluid from the urethra
As urethral cancer progresses or becomes more severe, additional symptoms may occur:
- Frequent urination or feeling the need to urinate without passing urine
- Difficulty emptying the bladder
- Urinary incontinence (inability to control urine)
- Enlarged lymph nodes in the groin, near the tumor
It's important to note that these symptoms can also be caused by other conditions. If you experience any of these symptoms, it's crucial to consult with a healthcare professional for an accurate diagnosis and appropriate treatment.
To diagnose urethral cancer, the following examinations, tests, and procedures are commonly performed:
- Physical exam: Your healthcare provider will conduct a physical exam to look for physical signs of a medical problem, such as pain, swelling, or the presence of masses in the body.
- Pelvic exam for women: The healthcare provider will check the vagina, cervix, uterus, fallopian tubes, ovaries, and rectum for signs of disease.
- Lab tests: Specific lab tests, such as blood or urine tests, may be recommended to gather more information and help with the diagnosis.
- Imaging studies: Your healthcare provider may suggest imaging studies like CT scan to get a better view of the affected area.
Additional examinations, tests, and procedures to determine the part of the urethra with cancer and the stage of cancer may include:
- Cystourethroscopy: A cystoscope is passed into the urethra to visualize any tumors or abnormalities along the urethra and in the bladder. This procedure is usually done as an outpatient with local anesthesia.
- Biopsy: A biopsy is necessary to confirm a cancer diagnosis. During this procedure, a sample of tissue is taken from the suspicious area for further examination.
It's important to discuss these tests and procedures with your healthcare provider to determine which ones are appropriate for your individual situation.
The goals of treatment for distal urethral cancer are to remove or destroy the cancer cells and prevent the cancer from spreading further. The recommended treatments and their mechanisms of action include:
- Surgery: Surgery is the most common treatment for urethral cancer. For distal urethral cancer, it may involve removing the cancer using a tool inserted into the urethra. An electric current or laser may be used in some cases.
- Radiation therapy: This treatment uses beams of intense energy to target and destroy cancer cells. It can be used alone or in combination with surgery or chemotherapy.
It's important to note that specific medication types and therapeutic procedures may vary depending on individual circumstances. Always consult with your healthcare professional for personalized advice.
