Difficulty urinating can be associated with other non-cancerous conditions in men, such as an enlarged prostate, but if this symptom occurs in other men, such as blood in the urine or pelvic pain, bladder cancer should be investigated.

6. Unexplained weight loss and fatigue
   In the later stages of bladder cancer, general symptoms such as unexplained weight loss and fatigue are present. As the body fights cancer, appetite decreases and energy levels drop. Cancer interferes with the body’s metabolism and immune system, which can affect these symptoms.

Although weight loss and fatigue can be caused by a variety of health problems, if it is accompanied by urinary tract problems, it may be a sign of bladder cancer and should be evaluated by a professional.
