Here are 10 signs to watch for:
10 Signs of Bladder Cancer
1. Blood in the Urine (Hematuria)
-
Most common early sign
-
Urine may look pink, red, or cola-colored
-
Can be intermittent and painless
2. Frequent Urination
-
Needing to urinate more often than usual
-
Especially noticeable at night (nocturia)
3. Urgency to Urinate
-
Sudden, strong need to go
-
Feeling you can’t hold it, even if the bladder isn’t full
4. Painful Urination (Dysuria)
-
Burning or discomfort while urinating
-
Often mistaken for a urinary tract infection (UTI)
5. Trouble Urinating or Weak Stream
-
Difficulty starting urination
-
Slow or interrupted urine flow
6. Lower Back or Pelvic Pain
-
Dull ache in lower abdomen, pelvis, or lower back
-
Usually on one side
7. Recurrent UTIs
-
Frequent infections without obvious cause
-
Antibiotics may provide only temporary relief
8. Fatigue
-
Persistent tiredness without a clear reason
-
Often due to anemia from chronic blood loss
9. Swelling in Legs
-
Rare but possible if cancer affects nearby veins or lymph nodes
10. Unexplained Weight Loss
-
Significant weight loss without dieting
-
Can indicate more advanced disease
Important Notes
-
Early bladder cancer is often painless, making blood in the urine the most crucial early warning sign.
-
Many symptoms overlap with UTIs, kidney stones, or other urinary conditions, so don’t ignore recurring issues.
When to See a Doctor
-
Any blood in the urine, even if it appears only once
-
Persistent urinary changes (frequency, urgency, pain)
-
Recurrent urinary infections or unexplained fatigue
✅ Bottom line: Bladder cancer is a “silent killer” because it can develop without pain or obvious signs. Early evaluation of urinary changes can save lives.
