The progression rate of bladder cancer?


Dear Dr.
Sun: I would like to inquire about the progression speed of bladder cancer from the initial discovery of painless hematuria to stage IV bladder cancer (from bladder neck metastasis to the prostate).
What is the fastest time frame for this progression? I was diagnosed with stage IV bladder cancer in just about 10 months.
What examinations or follow-ups should be conducted during this period to facilitate early detection and treatment?

Eric, 50~59 year old female. Ask Date: 2023/02/28

Dr. Sun Hongshun reply Urology


Hello Eric: Regarding cancer progression, the scientific and medical communities still cannot provide any definitive conclusions! It is essential to have regular health check-ups or to honestly inform your physician when you notice any abnormalities in your body (don’t be afraid that the doctor might think you are being overly cautious).
If you don’t communicate or seek medical attention, you may miss critical opportunities! In today's world, seeking medical care is very convenient.
If you have any issues, please consult a doctor directly (including urine tests, ultrasounds, urine cytology, CT scans, bone scans, and laryngoscopies).
All of these procedures need to be performed at a hospital (of course, the patient must also consent to the examinations).
I wish you a smooth resolution to your health issues (find a good physician for chemotherapy followed by surgery), and afterwards, it is "crucial" to have regular follow-ups.

More Info


Bladder cancer is known for its variable progression rates, which can differ significantly from one patient to another. The speed at which bladder cancer progresses from an early stage to an advanced stage, such as stage IV, can depend on several factors, including the tumor's grade, the patient's overall health, and the presence of risk factors such as smoking or exposure to certain chemicals.

In your case, you mentioned that the progression from the initial discovery of painless hematuria (blood in urine) to a diagnosis of stage IV bladder cancer occurred within approximately 10 months. This rapid progression is not uncommon, particularly in cases of high-grade tumors, which tend to grow and spread more quickly than low-grade tumors. High-grade tumors are more aggressive and have a higher likelihood of invading surrounding tissues and metastasizing to other organs, such as the prostate in your case.

To address your concerns about early detection and monitoring, it is crucial to understand the recommended follow-up procedures for individuals diagnosed with bladder cancer. After an initial diagnosis, regular surveillance is typically advised. This may include:
1. Cystoscopy: This is a procedure where a thin tube with a camera is inserted into the bladder through the urethra. It allows the doctor to visually inspect the bladder for any new tumors or changes. Cystoscopy is usually performed every three to six months in the first two years after diagnosis, depending on the tumor's characteristics.

2. Urinary Cytology: This test examines urine samples for cancerous cells. It can be a useful adjunct to cystoscopy, although it is not as sensitive as direct visualization.

3. Imaging Studies: Depending on the stage and characteristics of the cancer, imaging studies such as CT scans or MRIs may be recommended to assess for any metastasis or changes in the bladder and surrounding structures.

4. Regular Follow-ups: Regular appointments with your urologist or oncologist are essential for monitoring your condition and adjusting treatment plans as necessary.

5. Symptom Monitoring: Patients should be vigilant about any new symptoms, such as changes in urinary habits, pelvic pain, or weight loss, and report these to their healthcare provider promptly.

In terms of the timeline for progression, while some bladder cancers can progress rapidly, others may remain indolent for years. The average time from diagnosis to progression to advanced stages can vary widely, but it is generally understood that high-grade tumors can progress within months, while low-grade tumors may take years to advance.

In conclusion, if you have concerns about the speed of progression of your bladder cancer, it is essential to maintain open communication with your healthcare team. They can provide personalized recommendations for monitoring and managing your condition based on the specific characteristics of your cancer. Early detection through regular follow-ups and surveillance can significantly impact treatment outcomes and overall prognosis.
