What are the Symptoms of Bladder Cancer in Humans?

Bladder cancer is a type of cancer that starts in the cells lining the bladder, which is the organ responsible for storing urine. The symptoms of bladder cancer can vary depending on the stage and type of the cancer, but common signs and symptoms may include:

  • Blood in the Urine (Hematuria): The most common and often the first noticeable symptom of bladder cancer is blood in the urine. This may make the urine appear pink, red, or brown. Hematuria can be painless or associated with discomfort while urinating.
  • Frequent Urination: People with bladder cancer may experience a need to urinate more frequently than usual.
  • Painful Urination: Some individuals with bladder cancer may experience pain or a burning sensation during urination.
  • Lower Abdominal Pain: Pain or discomfort in the lower abdomen is a symptom that can occur, particularly in more advanced cases.
  • Back Pain: In some cases, bladder cancer may cause back pain, especially if the cancer has invaded the nearby tissues or organs.
  • Pelvic Pain: Pain in the pelvis, including discomfort in the area between the anus and the genitals (perineum), can occur.
  • Changes in Urinary Habits: Changes in urinary habits, such as increased urgency or difficulty starting to urinate, may be experienced.
  • Unexplained Weight Loss: In advanced stages of bladder cancer, unexplained weight loss can occur.
  • Fatigue: Ongoing fatigue and weakness can be a symptom, especially in more advanced cases.
  • Swelling in the Lower Legs: Swelling in the legs, known as edema, may develop in cases where the cancer has blocked the flow of urine from the bladder.

It’s important to note that these symptoms can also be caused by other, non-cancerous conditions, such as urinary tract infections or benign prostate hyperplasia (in men). However, the presence of any of these symptoms, especially blood in the urine, should not be ignored. If you experience any concerning symptoms related to your urinary system, it is advisable to consult a healthcare professional for a thorough evaluation and appropriate diagnostic tests, such as a cystoscopy, imaging studies, or urine tests. Early detection and treatment of bladder cancer can significantly improve outcomes.
