The early symptoms of bladder cancer can vary, and sometimes there might be no symptoms at all in the initial stages. However, some common early signs and symptoms of bladder cancer may include:

1. Blood in Urine (Hematuria): This is the most common early symptom. Urine may appear pink, red, or cola-colored due to the presence of blood. However, blood in the urine doesn't always indicate bladder cancer and can be caused by other conditions as well.

2. Frequent Urination: Need to urinate more often than usual, especially if only a small amount of urine is passed each time.

3. Pain or Burning Sensation During Urination: Discomfort or pain while urinating, similar to the feeling of a urinary tract infection.

4. Pelvic Pain: Pain in the pelvic area, which may be a sign that the cancer has spread or grown into nearby tissue.

5. Back Pain: If the cancer has reached an advanced stage, it may cause pain in the lower back or sides.

6. Changes in Urinary Habits: Changes in urinary patterns or urgency, even without an infection, could be indicative of bladder cancer.

It's important to note that these symptoms can also be caused by conditions other than bladder cancer, such as urinary tract infections or kidney stones. However, if any of these symptoms persist or seem unusual, it's advisable to consult a healthcare professional for proper evaluation and diagnosis. Early detection and treatment can significantly improve outcomes for bladder cancer.
