# Symptoms and Phases of Bladder Cancer
Bladder cancer progresses in different stages, depending on how deep the tumor has grown into the bladder margin and whether it has spread. The course and symptoms vary greatly by stage. This tab describes what happens at each stage, which complaints typically occur, and what is known about the duration and prognosis per phase.

Stage 0 and I: Superficial tumour (non-muscle invasive)
In these early stages, the tumor is still in the lining of the bladder (the urothelial layer) and has not grown into the muscle wall.
**Symptoms:**
- Blood in urine (usually the first and most prominent sign) — sometimes visible, sometimes only microscopically present
- More frequent urination than normal
- Burning sensation when urinating
- Lower abdominal pain or pressure
These symptoms are similar to an infection but persist and do not go away on their own. Many patients report to the doctor because they see blood in their urine, which feels alarming but does not mean an acute emergency at this stage.
**Treatment and follow-up process: **
After diagnosis, endoscopic treatment (transurethral resection) usually follows to remove the tumor. Many patients then receive intravesical therapy — drugs that are injected directly into the bladder — to prevent the tumor from returning. This process can take months to years, with regular cystoscopies (viewing tests) to supervise.
**Course and survival: **
The majority of patients with stage 0-I bladder cancer remain in this phase without further expansion. However, some of these tumors still grow into deeper layers. Research shows that around 30-40% of patients with high-risk non-muscle invasive bladder cancer eventually relapse (a new tumor in the same location or elsewhere in the bladder). For low-risk patients, this percentage is lower. These figures are based on large cohort studies and say nothing about individual situations — some people never suffer again, others get repeated tumours.
The five-year survival rate for stage 0-I is approximately 90-95%, but this depends heavily on the patient, size and type of tumour, and compliance with follow-up examinations.

Stage II and III: Muscle-invasive tumour
From stage II onwards, the tumor has grown into the muscular wall of the bladder. This changes the prognosis and treatment strategy significantly.
**Symptoms:**
- Persistent blood in the urine (sometimes more than in earlier stages)
- Frequent and urgent urination
- Pain in the lower abdomen or central pelvic area, sometimes also in the back
- Weight loss (as the disease progresses)
- Fatigue and general malaise
- Sometimes inability to urinate completely; urinary stasis (accumulation of urine)
The pain becomes stronger and more constant than in the superficial stages. Patients often describe it as a dull, nagging feeling that doesn't go away with acetaminophen. Nocturnal urination gets worse, interfering with sleep.
**Treatment and follow-up process: **
For muscle-invasive bladder cancer, radical cystectomy is usually considered — surgical removal of the entire bladder, surrounding lymph nodes, and (in men) prostate and testicles; in women, also uterus and ovaries. Some patients receive chemotherapy before surgery (neoadjuvant therapy) to reduce the size of the tumor. After removal of the bladder, urine must be drained in another way: via an ileum conduit (artificial opening to the outside) or a continent reservoir (artificial bladder made from intestinal tissue).
Radiation therapy is an alternative for patients who are unable or unwilling to operate, and is also sometimes used after tumour remains remain.
**Course and survival: **
This stage is more severe. Without treatment, the tumor grows into surrounding organs and spreads to lymph nodes and beyond. With treatment — especially the combination of neoadjuvant chemotherapy and cystectomy — many patients achieve complete remission (disappearance of visible tumor).
The median five-year survival after radical cystectomy for stage II-III is estimated in the literature at 50-65%, depending on the precise extent of the tumor and whether lymph nodes are involved. These are population figures from studies over the past 10-15 years; individual survival depends on many factors (age, overall health, complications from surgery, side effects of chemotherapy).

Stage IV: Metastatic bladder cancer
When bladder cancer spreads to distant organs — usually lungs, liver, bones or brain — it is stage IV. This is generally no longer curable, but is treatable.
**Symptoms:**
- All symptoms of stage II-III, often worse and more constant
- Severe bleeding (heavy blood in the urine, sometimes with clots)
- Abdominal swelling (abdominal distension) due to fluid accumulation
- Nausea and loss of appetite
- Pronounced fatigue and weight loss
- Bone pain (if bones are affected)
- Cough or shortness of breath (if lungs are affected)
- Confusion or headache (rare, but can occur with brain metastases)
Daily functioning is severely limited. Many patients cannot continue their normal work or activities. The focus shifts from cure to symptom management and quality of life.
**Treatment and follow-up process: **
Systemic chemotherapy (for example, cisplatin-containing regimens) is the cornerstone of treatment. For patients not suitable for chemotherapy (for example, due to poor kidney function or advanced age), immunotherapies (checkpoint inhibitors) or other systemic treatments may be considered. Radiotherapy can help relieve local symptoms such as pain and bleeding.
Supportive care — pain relief, anti-nausea medication, fluid balance, psychological support — plays an important role.
**Course and survival: **
Stage IV bladder cancer has an unfavorable prognosis. Without treatment, median survival is a few months. With chemotherapy, some patients can achieve a partial response, which relieves symptoms and can extend survival to 12-18 months on average, sometimes longer. These are population figures from studies in recent years; individual differences are very large and depend on the location and extent of metastases, the patient's overall health, and how well they respond to treatment.
Recent research (articles from 2026) signals possible roles for newer agents (such as sacituzumab govitocan and enfortumab vedotin), but these are not yet standard treatment and their place in the treatment regimen is still being investigated.

Special situations
**BCG-unresponsiveness in non-muscle-invasive bladder cancer:**
Approximately 5-10% of patients with high-risk non-muscle-invasive bladder cancer do not respond to standard intravesical BCG therapy (vaccination in the bladder). For these patients, alternatives are considered: chemotherapy agents in the bladder, radiotherapy, or in severe cases cystectomy. This group has a higher risk of progression to muscle-invasive stage.
**Bleeding in advanced stage:**
In patients with advanced bladder cancer, severe bleeding from the bladder can occur. This can be very alarming — massive bleeding with large blood clots in the urine. This requires acute hospitalization and treatment, sometimes radiotherapy or hemostasis procedures to stop the bleeding.

When to contact your healthcare provider?
**Emergency contact (go directly to hospital or emergency room):**
- Massive bleeding in the urine with significant blood loss, dizziness or fainting
- Inability to urinate (acute urinary retention), accompanied by severe pain
- Sudden severe pain in abdomen, back or pelvis
- Fever above 38.5°C with other symptoms of blood poisoning (very rapid heart rate, confusion)
**Regular appointment (call the next working day):**
- Increasing blood loss in the urine, especially if it is persistent
- New or worsening pain despite medication
- Sudden deterioration of overall condition, severe fatigue or weight loss
- Side effects of treatment that limit you in daily life
- Questions about follow-up examinations or when you need to return
